Single dose of Covid-19 vaccine sufficient for already infected people: Study | India News
Hyderabad: A Single dose of covid-19 Vaccination enough for one infected person Because there was a greater antibody response compared to those with no prior infection, according to a Study AIG Hospital disclosed on Monday.
City-based AIG Hospital recently published a study conducted on 260 healthcare workers, who were vaccinated between January 16 and February 5, in the International Journal of Infectious Diseases (a peer-reviewed journal).
The study was designed to evaluate the immunological memory response in those patients.
All patients were given Covishield Vaccination
The study also reported that the memory T-cell response elicited by a single dose of the vaccine was significantly greater in the previously infected group than in those with no prior infection.
Commenting on the impact this study may have on overall vaccine administration strategy, Dr D Nageshwar ReddyChairman, AIG Hospitals, and a co-author of the study, said the results show that people who have been infected with Covid-19 do not need to receive two doses of the vaccine because one dose can produce a stronger antibody and memory cell response than two doses for those who have not been infected.
This will help significantly at a time when there is a shortage of vaccines in the country and more people can be covered using the saved doses, Dr Reddy said.
Once a sufficient number of people have been vaccinated to achieve herd immunity, these patients who have been infected and received only one dose can receive a second dose of the vaccine, he added.
At this point, all our strategies should be directed towards mass distribution of available vaccines and to cover maximum number of people with at least one dose, added Dr. Reddy.
