Professor Chandima Jeewandara of Sri Jayewardenepura University has said that the system of giving Sinovac vaccine to prevent covirus infection in Sri Lanka is wrong.

He noted that the second dose should be given 3 weeks after the first dose of Sinovac vaccine. However, he said that the biggest problem was the action taken by the Ministry of Health to give the second dose to the people of Sri Lanka after 4 weeks.

A second vaccination at 3 weeks enhances immunity to coccidiosis at 4 weeks. However a further one week delay may delay the increase in immunity.

He points out that this is an injustice done to the people. He noted that the Ministry of Health did not accept the loan, which was first announced in May, to provide a second vaccine within 3 weeks of the Sinovac vaccine being given.

He added that in the context of the rapid spread of the delta virus in the country, it is confusing that Sri Lanka is not getting the vaccine immediately despite the massive availability of it. At the same time, it is noteworthy that more and more people in Sri Lanka are being vaccinated against synopam.
