Vaccines effective in combating mutated Covid variants, protecting beneficiaries from severe illness ANI | Updated: May 26, 2021 14:45 IST New Delhi [India], May 26 (ANI): With several cases of Covid-19 infections being reported after partial or full vaccinations, concerns have been raised on the efficacy of vaccination against the mutated variants of the novel coronavirus. Allaying these concerns, a new study emphasises that vaccines have been found effective against mutations of the Covid-19 virus and protects against severe illness. "Infections occurring two weeks after the full vaccination have been referred to as 'Break Through Infections' or BTI. Vaccines were found to be effective in combating mutated variants and protect the vaccinated from severe illness, hospitalization, or death", said findings of the research by Indraprastha Apollo Hospitals.
