Pune: With the SARS-COV-2 variant which tends to determine the next phase of the Covid-19 pandemic, scientists at the National Institute of Virology (NIV) here have said that the Covaxin booster dose can provide solutions to threats posed by threats.
A growing virus and offers “long-term protection.” The dose of booster against Covid is being explored in several countries with other vaccines.
Similar research was also considered in India, said Director of ICMR-Niga Priya Abraham.
A booster shot will come after the first two doses of any vaccine and may have to be given regularly (maybe after one or two years, or later) to maintain the immune system prepared against the SARS-COV-2 variant.
Someone who receives a booster does not have to repeat the schedule of two doses.
“Covaxin can be more effective in dealing with variants that arise.
It can play a useful role as a booster vaccine because the antibodies and cells of the immune system (installed by covaxin) are able to recognize and neutralize more protein from viruses, regardless of protein spike,” said Abraham.
Booster Shots with all the non-active virus vaccines have been proven to work well after two vaccine doses.
“Inactive vaccines can trigger strong immune reactions, although it may not be the same as the immune response to the attenuated vaccine.
So, someone might need a booster shot” added Abraham.
