A study by a leading private chain of hospitals found that 92 per cent fully vaccinated healthcare workers (HCW) developed only a mild Covid-19 infection. The study involved 16,000 healthcare workers who received the vaccine between January and May. Vaccinated HCWs did not need severe outcomes like ICU care.

The study showed that only six per cent HCWs got infected after taking both doses, while seven per cent who got infected post-vaccination developed moderate illness requiring oxygen support, only one per cent got severe illness requiring ICU care.
