Leading hospital chain, Fortis Healthcare on Thursday said 92 percent of the fully vaccinated healthcare workers developed only mild COVID-19 infections. A multi-centre study on a cohort of over 31,000 vaccinated healthcare workers of a leading private healthcare firm, spanning across the country, has found that Covid vaccine provided protection against infection in "95 percent" of the beneficiaries, hospital authorities claimed on Wednesday. ''The evidence-based study highlights that 92 percent of the fully vaccinated healthcare workers amongst those who acquired infection post-vaccination developed only mild COVID-19 infection, largely recovering under home care, despite a surge in serious infections during the second wave of the pandemic,'' Fortis said. "About 99 percent of HCWs who received both first and second doses of the (Covid) vaccine did not face severe outcomes, as in ICU care or mortality. Also, after receiving both the doses, only 6 percent of the staff got infected," the Fortis group claimed in the statement. The study further found that, amongst those who turned COVID-19 positive post-vaccination, just one percent of fully vaccinated healthcare workers developed severe illness requiring ICU care/ventilator support. According to a statement issued by Fortis, the study assessed around 16,000 healthcare workers who had been administered both first and second doses of vaccine between January 2021 and May 2021. ''The overall findings of the study emphasize that the vaccines available in India for COVID-19 are effective and do offer protection against SARS-CoV-2 virus,'' the statement read.
