A multi-centre study has found that Covid vaccine provided protection against infection in "95 percent" of the beneficiaries, hospital authorities claimed. The study by Apollo Hospitals took place over four and a half months, from January 16 to May 30 and covered 31,621 healthcare workers who had received either both doses or the first dose of Covishield or Covaxin, a hospital spokesperson said.

Dr. Anupam Sibal, Group Medical Director and senior pediatric gastroenterologist, Apollo Hospitals Group said, "The results showed that Covid vaccines provided protection in more than 95 per cent of the recipients and that post-vaccination infection (PVI) occurred in only 4.28% (1355 out of 31,621) of the vaccinated healthcare workers".

"The finding also showed that only 90 cases or 0.28 per cent of them required hospitalisation, with only three cases or 0.009 per cent requiring ICU admission," he claimed. The most important finding of the study was that there were "no deaths in case of COVID infection after vaccination", he was quoted as saying in a statement issued by the hospital.

Among the cohorts, Covishield was administered to 28,918 healthcare workers (or 91.45 pc of them), while 2703 (8.55 per cent) received Covaxin. Also, 25,907 or 81.9 per cent of the healthcare workers were fully vaccinated, having received both doses of the vaccine, while 5,714 or 18.1 per cent had received only the first dose, the doctor said.

The incidence of PVI in those who had been administered Covishield was 4.32 per cent and in those who had received Covaxin was 3.85 per cent, according to Dr. Raju Vaishya, one of the authors of the study. The findings of the study are under consideration for publication in a peer-reviewed medical journal, the statement said.

"The main conclusions from the study are that post-vaccination infections are usually minor and vaccination helps to prevent severe infection, ICU admissions, and death," he added. Sharing more details on the study, a senior official of the hospital said, "The majority of infections occurred after two weeks of the last vaccination dose, at an average of six weeks. 43.6 per cent of infections occurred in HCWs below the age of 30, and 35.42 percent in those in the 31-40 year age group."
