Study Key Points: Vaccines give shield from severe illness against Covid variants

A study conducted by a Delhi-based Hospital reveals that Vaccines have been found to be effective in combating mutated variants and protect the vaccinated individual from severe illnesses, hospitalization, or death.

The study, conducted by Indraprastha Apollo Hospitals, that include 69 symptomatic healthcare workers working at the hospital, who were tested positive for Covid-19 after their vaccination with the Covishield vaccine during the first 100 days of the vaccination drive earlier this year.

The study was conducted amid several reported cases of infections after partial or complete vaccination, occurring in a small percentage of people. Concerns have been raised on the efficacy of vaccination against the mutated variants of Covid-19. The study analyzed nasopharyngeal samples for genome sequencing, in collaboration with the National Centre for Disease Control (NCDC). The study was conducted between January 16 and April 24.

"Genome Sequencing is the key test to identify the nature of the virus and the variants that may emerge. "Currently, this facility is available in only 10 select Government organizations, but such testing facilities are now being increased in the near future by the Government of India," the hospital said in a statement.

One of the key authors of this study, Raju Vaishya, Senior Consultant, Orthopedics, Indraprastha Apollo Hospitals said, "We noticed that the post-vaccination SARS-COV-2 infections were seen only in a small subset of our healthcare workers.
