A study conducted by the Apollo Hospital Group suggests that the Coronavirus vaccination provides protection up to 97 per cent. The study was carried out to find out the occurrence of the SARS-CoV-2 infection among the symptomatic-vaccinated healthcare workers (HCWs) with the objective to the seriousness of their disease.
About 3,235 HCW were included in the study, in which 2480 have received both doses while 755 got a single shot.
The study displayed that Covid symptoms were primarily less severe after the vaccination.
The symptomatic post-vaccination infections analysed in these HCWs shows that around 85% of 3235 which counts up to 2.63 per cent of vaccinated Health care workers, had contracted the infection after being inoculated during the study period.

The study stated, "Of these, 65 (76.5 per cent) were fully vaccinated (FV), and 20 (23.5 per cent) were partially vaccinated (PV) and the protection rate of vaccination was 97.4 per cent."
It also observed the odds ratio of obtaining infection among females that was 1.84 times huge, which it explains as "mainly because of their greater involvement in the patient care as for nursing personnel."
The chances of acquiring the virus were greater in medical and nursing staff as compared to the paramedical, administrative and supporting faculty.
Among those HCWs who were part of the study only 2 needed hospitalization accounting for 0.06 per cent, none required ICU admission and there were no deaths reported.
