Health care workers are the first beneficiaries in the priority group have received Jab since January this year and is fully immunized in March.
Will antibodies decrease after this period? Will there be a need for a booster dose? There are countries like China and Russia that have started a booster dose.
“To understand this, we collect samples and have started a study,” said Prof.
Sunil Setyhi, Immunology in PGI.
Explain the production of antibodies, he said, “sometimes the level of antibodies decreases as antibodies to form cells developing and contracting.
During this contraction phase, most antibodies form dead cells and some are left as memory cells t and B.
These cells are resistant Old and protect against infection.
Vaccines produce memory cells and produce antibodies and if needed during infection, “he said, adding,” but in some booster dose infections needed.
“There are ongoing international studies that have seen initial indications show that the level of antibodies Triggered by most Covid-19 vaccines fell.
But it is uncertain whether there is a decrease in protection against the virus.
“Low antibodies do not indicate that immunity has decreased because there are memory cells that produce these antibodies from time to time,” said Prof.
Sunil.
What scientists do not know is whether this drop reflects a decrease in protection against viruses.

There are other places that also do this,” said Prof.
Sunil.
