Vaccination News: Antibodies made from vaccine are reducing delta variant of corona, need to give third dose of vaccine

 

Highlights:

  • ICMR research has revealed that the delta variant is dominating the antibodies
  • It has been found in the study that infection with corona is acting like the first dose of vaccine.
  • Therefore, people who have never been infected may need a third dose of the vaccine.

Pune/New Delhi
of corona virus delta variant Antibodies made from vaccines are dominating. The Indian Council of Medical Research (ICMR) has found that the antibodies of some of those taking the Kovidshield vaccine are getting infected with the delta variant. In such a situation, experts are also suggesting to give the third dose of the vaccine.

Is the delta variant up to 4.5 times more dangerous than the old corona?

The ICMR found that the delta version reduced the antibodies produced by the first dose of Covishield by 4.5 times and the antibodies formed after the second dose by 3.2 times as compared to the older SARS-CoV-2 version with the D614G mutation. The D614G mutation was found in the country during the initial phase of the Kovid-19 epidemic last year. Dr. Samiran Panda, Head of Epidemic and Infectious Diseases Department at ICMR said, “Such information will help in deciding the strategy for the vaccination campaign. Perhaps the need for a third dose against Kovid-19 may also come to the fore.

What does ICMR research say?
ICMR collected serum samples from healthy people who had taken one or both doses of Covishield to ascertain the effect of the delta variant. Serum samples were also taken of those who had taken one or both doses of Kovishield after recovering from corona infection. Then after taking the vaccine, the serum samples of the infected people were collected. Dr Pragya Yadav of the National Institute of Virology, who was part of the research team, said that among those who recovered from the infection and those who got infected after taking the vaccine, were never infected but had more antibodies than those who had taken one or two doses of Kovishield. was found.

To whom should the third dose of the vaccine be given?
Dr. Panda said, ‘This indicates that in those who got Kovid, the corona virus acted as the first dose of the vaccine. In this way, after recovering from the epidemic, after taking both the doses, antibodies were made in them three times. Similarly, people who were not infected but got infected after taking one or both doses of Covishield also never got infected but were found to have more antibodies than those who took one or two doses of Covishield. In such a situation, it can be said that those who have never been infected with the corona virus before or after taking the vaccine dose, they also need to give the third dose of Kovishield only after getting infected in them and after being cured, those who take the vaccine or get the vaccine. Antibodies will be able to develop after taking it, equal to the people who get infected.


Dr. Yadav said that for those who have recently recovered from Kovid, only one dose of the vaccine is sufficient. He said that in those who have never been infected, those people have developed antibodies from Covishield, there are only a few people in whom antibodies are not made even after taking the vaccine.
