HERD IMMUNITY: A good analogy is protection of calves in a herd of wild buffalos from predation by leopards. A sizeable number of adult bulls and cows in the herd attack and repulse leopards. Once in a way, a leopard would succeed dragging a calf, but a large majority of calves survive to ensure the continuation of the species.

With the advent of coronavirus vaccines, the idea of herd immunity is gaining ground – but often misunderstood or considered something hard to fathom. Herd immunity means the resistance a community develops against an infectious disease, when a fraction of its residents above a threshold acquires immunity either by exposure to the pathogen or vaccination. Thus, achieving herd immunity could safeguard individuals who cannot be immunized for reasons of being too young, convalescent or because of inadvertent inaccessibility.

A good analogy is protection of calves in a herd of wild buffalos from predation by leopards. A sizeable number of adult bulls and cows in the herd attack and repulse leopards. Once in a way, a leopard would succeed dragging a calf, but a large majority of calves survive to ensure the continuation of the species. If leopards prey exclusively on buffalos, they might be starved into extinction. Buffalos and leopards live in the jungle because the latter also hunt other animals. Similarly, in absence of non-human reservoirs of the pathogen, herd immunity provides a way of controlling an infection causing an epidemic or a pandemic and the elimination of the causative agent.

 

History and theory of herd immunity

Epidemics originate when a pathogen invades a population devoid of immunity. Science fiction writer H.G. Wells in his novel, “The War of the Worlds”, says Martian invaders were not immune to earthly microbes and all died due to an infection. We are not so alien to viruses here and the ability to make antibody machinery to fight them are genetically imprinted in our bodies.

Even in olden days when precautionary measures remained completely unknown or misunderstood, maladies ended before everyone caught the infection. Those days, epidemics were considered divine punishments or expressions of anger of deities. The cause that receded them; attributed to prayers, rituals or offerings to the demons, has been in fact the natural herd immunity.

The Mahavamsa and the Elu Athanagalu Vamsa refer to a catastrophe during the reign of King Sri Sanga Bodhi (252-254 CE). According to the legend in the latter script; a demon named Ratharaksha came to Sri Lanka and cast a spell reddening the eyes of people who stared at it in fear. Many who looked at the eyes of those afflicted also developed red eyes and contracted the illness. Very high mortality thinned the population of the land and the distressed king, ritualistically confronted the demon driving it to exile. The version of the story in Mahavamsa is similar but implicate a female demon Ratarakshi. What is the infectious agent behind this outbreak? From the symptoms described and the extreme contagiousness implied, the illness that ravaged the kingdom seems to be measles. The herd immunity threshold of measles exceeds 95%. There was also a famine accompanying the epidemic. Presumably, malnutrition and absence of immunity greatly increased the measles death toll.

Ages ago people lived in isolated communities. Therefore, an infectious disease which decelerated and vanished after reaching herd immunity did not remerge until the immunized percentage was lowered by people born subsequently. Many epidemics, notably small pox and plague followed cyclic patterns for this reason. Later on, the establishment of vast human settlements and extensive migration, turned epidemics into pandemics and many diseases remained endemic. Historians have also argued that the consequent wider dispersion of diseases, boosted the immunity of the global human herd thereby escalating the population growth.

The idea of herd immunity was first introduced by the American veterinarian George Potter in 1917; he noted a cattle disease disappeared on its own when animals were not introduced to the herd from outside. He said disease resembled a fire which extinguished when all fuel has been consumed.

In 1919 bacteriologist W. Topley infected a few mice in a large colony with a germ. He observed the infection expanded, subdued and stopped after infecting only a certain percentage of mice. Further clarification of difference between individual immunity and herd immunity followed from the work of American statistician A.W. Hedrick. He studied the epidemiology of measles in United States 1900-1911 and concluded measles epidemics ceased when 68% of children under 15 years became immunised after contraction of the illness.

The idea of herd immunity was firmly established after invoking mathematics into epidemiology – mathematician turned physician Sir Ronald Ross pioneered the theme.

Ronald Ross, born in India 1857, received his education in the United Kingdom and returned to his country of birth after qualifying as a doctor. He joined the Indian Medical Service 1880 and worked in Bangalore badly infested with mosquitoes. At the time malaria was suspected to be associated with mosquitoes. Curious, Ronald strived hard to understand how it was transmitted. Mosquitoes in the place he lived has been a nuisance; he closed all stagnant pools in the vicinity of his residence and found the mosquito number falling drastically, but realized complete elimination would be an impossibility. When Ronald Ross was transferred to a station free of malaria, he declined to work in a locality free of malaria!

In 1895, Ronald Ross identified the malarial parasite in stomach of anopheles mosquitoes proving its mode of transmission. He was awarded 1902 Nobel Prize in Physiology for this work done in India.

Having found the cause of malaria; Ronald Ross determined to find a way to eradicate it and resorted to mathematics in attempting to find an answer. His remarkably insightful mathematical analysis revealed malaria could be eradicated by reducing the mosquito population below a threshold dependent on human population density, and the impossible task of destroying every anopheles mosquito was unnecessary. Following work of Ronald Ross, another physician A.G. Kendrick and biochemist W.O. Karnack both well versed in mathematics generalized Ronald Ross’s hypothesis, concluding the progress of infectious disease in a community depends on the average number of infected persons reproduced by one single carrier of the pathogen. If this number referred to as basic reproduction number (R) exceeds unity, the infection could expand into an epidemic whereas when the number is less than one the disease subsides after infecting a few. From statistics pertaining to the growth of an infection, the basic reproduction number can be estimated.

It is easy to see how an infection evolves depending on whether R is greater or less than one. Suppose 10 persons contracted with an infection with R=2 enters a susceptible population. On average, they pass sickness to 20 individuals and this 20 in return reproduce 40 cases – an endless series of ascending numbers. If R is less than one you obtain a descending sequence – implying cases die down.

 

Herd immunity threshold

Suppose a population of N persons includes a number M of individuals immune to a disease. The fraction of immunes in the population is M/N (M divided by N). From simple school arithmetic, it follows that the fraction of persons not immune (susceptible) is (1- M/N). In the presence of immunes, the basic reproduction number scale down proportionately to the fraction of the susceptible population so that the effective reproduction number is (1 –M/N) times R, written as (1-M/N) R. The threshold happens when the effective reproduction number is exactly equal to unity, implying (1 –M/N) R = 1 or equivalently M/N = 1 – 1/R. The fraction M/N given by the above formula, referred to as herd immunity threshold is normally expressed as a percentage. For example, measles being highly contagious, the basic reproduction number can take values close to 20. Setting R = 20 in the formula, we obtain M/N = 0.95. Expressed as a percentage, the herd immunity threshold for measles is 95. To protect a community against measles, over 95 percent of the population needs to be vaccinated.

Vaccinating a community to exceed the herd immunity threshold would not abruptly halt an epidemic. Although the incidence of the disease gradually decreases, vaccinations and containment measures have to be continued until positive cases disappear completely – smallpox was eradicated this way.

 

Can we achieve herd immunity to COVID-19?

Coronavirus vaccines have arrived sooner than expected – many countries including Sri Lanka expeditiously commissioning inoculation campaigns.

Vaccinations and continuous adherence to precautionary measures will undoubtedly tame the virus. However, it is premature to assume global herd immunity would follow and the pandemic will soon end.

According to some estimates an upper bound to basic reproduction number for COVID -19 is around 2.5. Formula M/N = 1- 1/R explained previously, imply that the herd immunity threshold corresponding to R = 2.5 is 60 percent. Vaccines may not be 100 percent efficacious. For an 80 percent effective vaccine, the above thresholds increase to 75 percent. The other question is how long the vaccine induced immunity would last. At the moment sufficient information is not available to decide how the duration of immunity will interfere with the herd immunity threshold and how often vaccinations need to be repeated.

If faster spreading variants of the virus take over, the basic reproduction number and therefore the herd immunity threshold will also increase. The variants may turn out to be more resistant to vaccines. Remodeling of vaccines to make them effective towards variants is technically feasible but would delay the immunisation protocols. The answer to the problem of variants and temporary immunity is speedy vaccination – obviously constrained by real world practicalities.

 

Decreasing trends of COVID -19 incidence

Many regions of the world have begun to see a decline in the number of COVID-19 cases and deaths – plausibly a combined outcome of preventive safeguards and immunity derived from exposure to the virus or vaccination.

Israel has given more coronavirus vaccinations per capita than any other country – around 50 percent given one dose and 35 percent both doses. Covid-19 cases are declining and the world is awaiting see the outcome of the Israel experiment.

The United Kingdom has vaccinated more than 30 percent of over 80s and noticed a dramatic reduction in COVID-19 related deaths in this group.

Prompt inoculation of a sizeable fraction of a community is not an easy task. We need to await patiently to see the effectuality of the vaccines.

Dependence of herd immunity threshold on preventive measures

The preventive strategies or so-called non-pharmacological interventions significantly reduce viral transmission thereby lowering basic reproduction number and therefore the herd immunity threshold. Wearing masks, social distancing, hand-sanitizing and ventilation are proven safeguards. There is some evidence and theoretical arguments to the effect that preventive measures not only reduce the risk of contracting the disease but those who catch the disease under such circumstances develop milder symptoms or recover soon, adding to the pool of immunes. Argument rest on inoculum theory of viral transmission, according which the intensity of the infection a patient develops depends on the number of virus particles to which he or she was exposed. Emphasizing this point authors of a recent article published in the prestigious medical journal Lancet appeal to the world to continue strict adherence to preventive measures. This is most prudent method to safeguard against new strains until vaccines are remodeled.

Vaccination priorities

Vaccine production, procurement and organization of immunization campaigns decide the rate at which a community could be vaccinated. These limitations necessitate imposition of priorities. The World Health Organization and individual nations have laid down priority categories. Everyone agree the first priority should be frontline health care workers. The second category the older persons (generally above 65) more vulnerable and at the risk of death after contracting the sickness. Those living under conditions of extreme congestion and poverty are also a priority group identified by WHO. The younger working class, although they are less susceptible to danger of COVID-19, needs to be vaccinated. The policy of neglecting the older group in favour of younger working class is not only unethical but also epidemiologically flawed. In modern societies the percentage older persons (above 65) and socially active are significant. They, being most vulnerable to contracting the sickness because of impaired immunity, if infected, could also be the super spreaders. Recent studies have confirmed the presence of super spreaders, who are mostly elderly patients carrying larger viral loads.

Social reaction to vaccination

Societies react to vaccinations within confines of two extremes: vaccine hesitancy and vaccine overconfidence. The former has prevented eradication measles in localities where the herd immunity threshold stands inordinately high. In some parts of the world, vaccine hesitancy confuses mass COVID-19 inoculation. The latter misconception equally undermines the control effort. Not wearing a mask or not adhering to social distancing because you got the jab is not right. Vaccines are not 100 percent effective and immunity sometimes slacken. People not wearing masks, believing assurance of safety after the jab creates social stigma for those not vaccinated to abandon the precautions.

Vaccines and non-pharmacological interventions will certainly suppress the virus. Rapid decline in reported cases in some parts of the world may be a sign of a distant herd immunity in that region – but what we want is a global effect. As WHO Director Tedros said, “Until we end the pandemic everywhere, we will not end it anywhere “

The heart-friendly health minister

Published

on

Dr. Ramesh Pathirana

by Dr Gotabhya Ranasinghe
Senior Consultant Cardiologist
National Hospital Sri Lanka

When we sought a meeting with Hon Dr. Ramesh Pathirana, Minister of Health, he graciously cleared his busy schedule to accommodate us. Renowned for his attentive listening and deep understanding, Minister Pathirana is dedicated to advancing the health sector. His openness and transparency exemplify the qualities of an exemplary politician and minister.

Dr. Palitha Mahipala, the current Health Secretary, demonstrates both commendable enthusiasm and unwavering support. This combination of attributes makes him a highly compatible colleague for the esteemed Minister of Health.

Our discussion centered on a project that has been in the works for the past 30 years, one that no other minister had managed to advance.

Minister Pathirana, however, recognized the project’s significance and its potential to revolutionize care for heart patients.

The project involves the construction of a state-of-the-art facility at the premises of the National Hospital Colombo. The project’s location within the premises of the National Hospital underscores its importance and relevance to the healthcare infrastructure of the nation.

This facility will include a cardiology building and a tertiary care center, equipped with the latest technology to handle and treat all types of heart-related conditions and surgeries.

Securing funding was a major milestone for this initiative. Minister Pathirana successfully obtained approval for a $40 billion loan from the Asian Development Bank. With the funding in place, the foundation stone is scheduled to be laid in September this year, and construction will begin in January 2025.

This project guarantees a consistent and uninterrupted supply of stents and related medications for heart patients. As a result, patients will have timely access to essential medical supplies during their treatment and recovery. By securing these critical resources, the project aims to enhance patient outcomes, minimize treatment delays, and maintain the highest standards of cardiac care.

Upon its fruition, this monumental building will serve as a beacon of hope and healing, symbolizing the unwavering dedication to improving patient outcomes and fostering a healthier society.We anticipate a future marked by significant progress and positive outcomes in Sri Lanka’s cardiovascular treatment landscape within the foreseeable timeframe.

A LOVING TRIBUTE TO JESUIT FR. ALOYSIUS PIERIS ON HIS 90th BIRTHDAY

Published

on

Fr. Aloysius Pieris, SJ was awarded the prestigious honorary Doctorate of Literature (D.Litt) by the Chancellor of the University of Kelaniya, the Most Venerable Welamitiyawe Dharmakirthi Sri Kusala Dhamma Thera on Nov. 23, 2019.

by Fr. Emmanuel Fernando, OMI

Jesuit Fr. Aloysius Pieris (affectionately called Fr. Aloy) celebrated his 90th birthday on April 9, 2024 and I, as the editor of our Oblate Journal, THE MISSIONARY OBLATE had gone to press by that time. Immediately I decided to publish an article, appreciating the untiring selfless services he continues to offer for inter-Faith dialogue, the renewal of the Catholic Church, his concern for the poor and the suffering Sri Lankan masses and to me, the present writer.

It was in 1988, when I was appointed Director of the Oblate Scholastics at Ampitiya by the then Oblate Provincial Fr. Anselm Silva, that I came to know Fr. Aloy more closely. Knowing well his expertise in matters spiritual, theological, Indological and pastoral, and with the collaborative spirit of my companion-formators, our Oblate Scholastics were sent to Tulana, the Research and Encounter Centre, Kelaniya, of which he is the Founder-Director, for ‘exposure-programmes’ on matters spiritual, biblical, theological and pastoral. Some of these dimensions according to my view and that of my companion-formators, were not available at the National Seminary, Ampitiya.

Ever since that time, our Oblate formators/ accompaniers at the Oblate Scholasticate, Ampitiya , have continued to send our Oblate Scholastics to Tulana Centre for deepening their insights and convictions regarding matters needed to serve the people in today’s context. Fr. Aloy also had tried very enthusiastically with the Oblate team headed by Frs. Oswald Firth and Clement Waidyasekara to begin a Theologate, directed by the Religious Congregations in Sri Lanka, for the contextual formation/ accompaniment of their members. It should very well be a desired goal of the Leaders / Provincials of the Religious Congregations.

Besides being a formator/accompanier at the Oblate Scholasticate, I was entrusted also with the task of editing and publishing our Oblate journal, ‘The Missionary Oblate’. To maintain the quality of the journal I continue to depend on Fr. Aloy for his thought-provoking and stimulating articles on Biblical Spirituality, Biblical Theology and Ecclesiology. I am very grateful to him for his generous assistance. Of late, his writings on renewal of the Church, initiated by Pope St. John XX111 and continued by Pope Francis through the Synodal path, published in our Oblate journal, enable our readers to focus their attention also on the needed renewal in the Catholic Church in Sri Lanka. Fr. Aloy appreciated very much the Synodal path adopted by the Jesuit Pope Francis for the renewal of the Church, rooted very much on prayerful discernment. In my Religious and presbyteral life, Fr.Aloy continues to be my spiritual animator / guide and ongoing formator / acccompanier.

Fr. Aloysius Pieris, BA Hons (Lond), LPh (SHC, India), STL (PFT, Naples), PhD (SLU/VC), ThD (Tilburg), D.Ltt (KU), has been one of the eminent Asian theologians well recognized internationally and one who has lectured and held visiting chairs in many universities both in the West and in the East. Many members of Religious Congregations from Asian countries have benefited from his lectures and guidance in the East Asian Pastoral Institute (EAPI) in Manila, Philippines. He had been a Theologian consulted by the Federation of Asian Bishops’ Conferences for many years. During his professorship at the Gregorian University in Rome, he was called to be a member of a special group of advisers on other religions consulted by Pope Paul VI.

Fr. Aloy is the author of more than 30 books and well over 500 Research Papers. Some of his books and articles have been translated and published in several countries. Among those books, one can find the following: 1) The Genesis of an Asian Theology of Liberation (An Autobiographical Excursus on the Art of Theologising in Asia, 2) An Asian Theology of Liberation, 3) Providential Timeliness of Vatican 11 (a long-overdue halt to a scandalous millennium, 4) Give Vatican 11 a chance, 5) Leadership in the Church, 6) Relishing our faith in working for justice (Themes for study and discussion), 7) A Message meant mainly, not exclusively for Jesuits (Background information necessary for helping Francis renew the Church), 8) Lent in Lanka (Reflections and Resolutions, 9) Love meets wisdom (A Christian Experience of Buddhism, 10) Fire and Water 11) God’s Reign for God’s poor, 12) Our Unhiddden Agenda (How we Jesuits work, pray and form our men). He is also the Editor of two journals, Vagdevi, Journal of Religious Reflection and Dialogue, New Series.

Fr. Aloy has a BA in Pali and Sanskrit from the University of London and a Ph.D in Buddhist Philosophy from the University of Sri Lankan, Vidyodaya Campus. On Nov. 23, 2019, he was awarded the prestigious honorary Doctorate of Literature (D.Litt) by the Chancellor of the University of Kelaniya, the Most Venerable Welamitiyawe Dharmakirthi Sri Kusala Dhamma Thera.

Fr. Aloy continues to be a promoter of Gospel values and virtues. Justice as a constitutive dimension of love and social concern for the downtrodden masses are very much noted in his life and work. He had very much appreciated the commitment of the late Fr. Joseph (Joe) Fernando, the National Director of the Social and Economic Centre (SEDEC) for the poor.

In Sri Lanka, a few religious Congregations – the Good Shepherd Sisters, the Christian Brothers, the Marist Brothers and the Oblates – have invited him to animate their members especially during their Provincial Congresses, Chapters and International Conferences. The mainline Christian Churches also have sought his advice and followed his seminars. I, for one, regret very much, that the Sri Lankan authorities of the Catholic Church –today’s Hierarchy—- have not sought Fr.

Aloy’s expertise for the renewal of the Catholic Church in Sri Lanka and thus have not benefited from the immense store of wisdom and insight that he can offer to our local Church while the Sri Lankan bishops who governed the Catholic church in the immediate aftermath of the Second Vatican Council (Edmund Fernando OMI, Anthony de Saram, Leo Nanayakkara OSB, Frank Marcus Fernando, Paul Perera,) visited him and consulted him on many matters. Among the Tamil Bishops, Bishop Rayappu Joseph was keeping close contact with him and Bishop J. Deogupillai hosted him and his team visiting him after the horrible Black July massacre of Tamils.

A fairy tale, success or debacle

Sri Lanka-Singapore Free Trade Agreement

By Gomi Senadhira
senadhiragomi@gmail.com

“You might tell fairy tales, but the progress of a country cannot be achieved through such narratives. A country cannot be developed by making false promises. The country moved backward because of the electoral promises made by political parties throughout time. We have witnessed that the ultimate result of this is the country becoming bankrupt. Unfortunately, many segments of the population have not come to realize this yet.” – President Ranil Wickremesinghe, 2024 Budget speech

Any Sri Lankan would agree with the above words of President Wickremesinghe on the false promises our politicians and officials make and the fairy tales they narrate which bankrupted this country. So, to understand this, let’s look at one such fairy tale with lots of false promises; Ranil Wickremesinghe’s greatest achievement in the area of international trade and investment promotion during the Yahapalana period, Sri Lanka-Singapore Free Trade Agreement (SLSFTA).

It is appropriate and timely to do it now as Finance Minister Wickremesinghe has just presented to parliament a bill on the National Policy on Economic Transformation which includes the establishment of an Office for International Trade and the Sri Lanka Institute of Economics and International Trade.

Was SLSFTA a “Cleverly negotiated Free Trade Agreement” as stated by the (former) Minister of Development Strategies and International Trade Malik Samarawickrama during the Parliamentary Debate on the SLSFTA in July 2018, or a colossal blunder covered up with lies, false promises, and fairy tales? After SLSFTA was signed there were a number of fairy tales published on this agreement by the Ministry of Development Strategies and International, Institute of Policy Studies, and others.

However, for this article, I would like to limit my comments to the speech by Minister Samarawickrama during the Parliamentary Debate, and the two most important areas in the agreement which were covered up with lies, fairy tales, and false promises, namely: revenue loss for Sri Lanka and Investment from Singapore. On the other important area, “Waste products dumping” I do not want to comment here as I have written extensively on the issue.

1. The revenue loss

During the Parliamentary Debate in July 2018, Minister Samarawickrama stated “…. let me reiterate that this FTA with Singapore has been very cleverly negotiated by us…. The liberalisation programme under this FTA has been carefully designed to have the least impact on domestic industry and revenue collection. We have included all revenue sensitive items in the negative list of items which will not be subject to removal of tariff. Therefore, 97.8% revenue from Customs duty is protected. Our tariff liberalisation will take place over a period of 12-15 years! In fact, the revenue earned through tariffs on goods imported from Singapore last year was Rs. 35 billion.

The revenue loss for over the next 15 years due to the FTA is only Rs. 733 million– which when annualised, on average, is just Rs. 51 million. That is just 0.14% per year! So anyone who claims the Singapore FTA causes revenue loss to the Government cannot do basic arithmetic! Mr. Speaker, in conclusion, I call on my fellow members of this House – don’t mislead the public with baseless criticism that is not grounded in facts. Don’t look at petty politics and use these issues for your own political survival.”

I was surprised to read the minister’s speech because an article published in January 2018 in “The Straits Times“, based on information released by the Singaporean Negotiators stated, “…. With the FTA, tariff savings for Singapore exports are estimated to hit $10 million annually“.

As the annual tariff savings (that is the revenue loss for Sri Lanka) calculated by the Singaporean Negotiators, Singaporean $ 10 million (Sri Lankan rupees 1,200 million in 2018) was way above the rupees’ 733 million revenue loss for 15 years estimated by the Sri Lankan negotiators, it was clear to any observer that one of the parties to the agreement had not done the basic arithmetic!

Six years later, according to a report published by “The Morning” newspaper, speaking at the Committee on Public Finance (COPF) on 7th May 2024, Mr Samarawickrama’s chief trade negotiator K.J. Weerasinghehad had admitted “…. that forecasted revenue loss for the Government of Sri Lanka through the Singapore FTA is Rs. 450 million in 2023 and Rs. 1.3 billion in 2024.”

If these numbers are correct, as tariff liberalisation under the SLSFTA has just started, we will pass Rs 2 billion very soon. Then, the question is how Sri Lanka’s trade negotiators made such a colossal blunder. Didn’t they do their basic arithmetic? If they didn’t know how to do basic arithmetic they should have at least done their basic readings. For example, the headline of the article published in The Straits Times in January 2018 was “Singapore, Sri Lanka sign FTA, annual savings of $10m expected”.

Anyway, as Sri Lanka’s chief negotiator reiterated at the COPF meeting that “…. since 99% of the tariffs in Singapore have zero rates of duty, Sri Lanka has agreed on 80% tariff liberalisation over a period of 15 years while expecting Singapore investments to address the imbalance in trade,” let’s turn towards investment.

Investment from Singapore

In July 2018, speaking during the Parliamentary Debate on the FTA this is what Minister Malik Samarawickrama stated on investment from Singapore, “Already, thanks to this FTA, in just the past two-and-a-half months since the agreement came into effect we have received a proposal from Singapore for investment amounting to $ 14.8 billion in an oil refinery for export of petroleum products. In addition, we have proposals for a steel manufacturing plant for exports ($ 1 billion investment), flour milling plant ($ 50 million), sugar refinery ($ 200 million). This adds up to more than $ 16.05 billion in the pipeline on these projects alone.

And all of these projects will create thousands of more jobs for our people. In principle approval has already been granted by the BOI and the investors are awaiting the release of land the environmental approvals to commence the project.

I request the Opposition and those with vested interests to change their narrow-minded thinking and join us to develop our country. We must always look at what is best for the whole community, not just the few who may oppose. We owe it to our people to courageously take decisions that will change their lives for the better.”

According to the media report I quoted earlier, speaking at the Committee on Public Finance (COPF) Chief Negotiator Weerasinghe has admitted that Sri Lanka was not happy with overall Singapore investments that have come in the past few years in return for the trade liberalisation under the Singapore-Sri Lanka Free Trade Agreement. He has added that between 2021 and 2023 the total investment from Singapore had been around $162 million!

What happened to those projects worth $16 billion negotiated, thanks to the SLSFTA, in just the two-and-a-half months after the agreement came into effect and approved by the BOI? I do not know about the steel manufacturing plant for exports ($ 1 billion investment), flour milling plant ($ 50 million) and sugar refinery ($ 200 million).

However, story of the multibillion-dollar investment in the Petroleum Refinery unfolded in a manner that would qualify it as the best fairy tale with false promises presented by our politicians and the officials, prior to 2019 elections.

Though many Sri Lankans got to know, through the media which repeatedly highlighted a plethora of issues surrounding the project and the questionable credentials of the Singaporean investor, the construction work on the Mirrijiwela Oil Refinery along with the cement factory began on the24th of March 2019 with a bang and Minister Ranil Wickremesinghe and his ministers along with the foreign and local dignitaries laid the foundation stones.

That was few months before the 2019 Presidential elections. Inaugurating the construction work Prime Minister Ranil Wickremesinghe said the projects will create thousands of job opportunities in the area and surrounding districts.

The oil refinery, which was to be built over 200 acres of land, with the capacity to refine 200,000 barrels of crude oil per day, was to generate US$7 billion of exports and create 1,500 direct and 3,000 indirect jobs. The construction of the refinery was to be completed in 44 months. Four years later, in August 2023 the Cabinet of Ministers approved the proposal presented by President Ranil Wickremesinghe to cancel the agreement with the investors of the refinery as the project has not been implemented! Can they explain to the country how much money was wasted to produce that fairy tale?

It is obvious that the President, ministers, and officials had made huge blunders and had deliberately misled the public and the parliament on the revenue loss and potential investment from SLSFTA with fairy tales and false promises.

As the president himself said, a country cannot be developed by making false promises or with fairy tales and these false promises and fairy tales had bankrupted the country. “Unfortunately, many segments of the population have not come to realize this yet”.
