Take that second jab without fail to fortify your body against Delta variant

Both doses of a COVID-19 vaccine were needed to protect a person against its highly contagious Delta variant, Dr. Chandima Jeewandara of the Allergy, Immunology and Cell Biology Unit, Department of Immunology Molecular and Molecular Medicine of the University of Sri Jayewardenepura said yesterday.

Dr. Jeewandara said that some people were raising questions about the efficacy of the vaccine they had taken due to the delay in receiving the second dose of the AstraZeneca vaccine  

“The effect of the first dose decreases after four months but that’s all the more reason to get the second dose, since the opportunity has now arrived,” he said. (RK)
