PUNE: Leading virologists have stressed on the need for strict adherence to the two-dose regimen of the Covid-19 vaccination, saying that while the first dose acts as a launchpad and primes the immune response, the second amplifies and makes the immune response against the virus stronger.
Against the looming concern that some of the beneficiaries in the priority groups might not turn up for the second dose of the vaccine after taking the first shot, virologists urged them not to deviate from the norm as the second dose adds to the durability of protection.
The first dose initiates an immunological response against the antigen introduced in the body through the vaccine. The body develops IgG and neutralising antibodies (protection) within three to four weeks of taking the first shot.
By yesterday evening, Covid doses had reached the 17 vaccination centres across the PMR. The Aundh district hospital is the centre which would offer Covaxin.
The first lot of vaccines reached Navi Mumbai as well on Wednesday
PUNE: The time taken to collate data of frontline workers largely policemen and staff of departments involved in Covid-19 management will be key to completion of Phase 2 of the vaccination drive. It will also determine when the third phase, meant for senior citizens and those with co-morbidities, can be rolled out.
As the country gears up for the rollout of the vaccine this Saturday, senior state health department officials said it could take 6-7 months to a year for the three phases to be completed and the vaccine be available for the general public.
