Coronavirus: Is it necessary for people who have been vaccinated to get a booster shot or not? Read the answer of the Chief Scientist of WHO
World Health Organization's chief scientist Soumya Swaminathan has recently said that there is no need to confirm or reject the need for a booster shot after the Kovid-19 vaccination. Not enough information. The United Kingdom has launched a nationwide study to find out whether a third shot of the same vaccine would provide more coverage to people who have already been fully vaccinated. Chances of re-infection are low but such infected patients are definitely found all over the world.
The Russian Direct Investment Fund, which markets Sputnik V, said it would offer a booster shot to other vaccine makers. This shot has a high potential to work against the delta variant of the coronavirus found for the first time in India. The RDIF said this is because Sputnik V is more effective against the delta variant than other vaccine manufacturers.
Many needy did not get full vaccination
All current vaccines consist of two doses. It is not clearly known how long the effect of vaccination lasts and many countries are considering the annual shot. Soumya Swaminathan said it was too early to consider this as many high-risk people in most parts of the world have not yet received full vaccination. He said data from countries starting additional precautionary immunizations later this year - especially for vulnerable people whose immunity to SARS-CoV-2 may rapidly decline - would inform WHO's guidance.
Delta variant of Corona first surfaced in India
The delta variant of Kovid-19 is becoming more prevalent in the world than other forms of this virus because it is transmitted much faster. Soumya Swaminath claimed this on Friday. The delta form of Kovid-19 first appeared in India. According to the Kovid-19 weekly epidemiological update released by the WHO on June 15, the delta form is now being found in about 80 countries. B.1.617.2 The delta form was first detected in India in October 2020.
