  • According to it, vaccination had 95 per cent efficacy against severe disease including the Delta variant and Alpha variant.
  • Vaccine is having the efficacy of 80 per cent in protecting against any infection from these variants.
  • However, vaccines are less effective against asymptomatic disease or against transmission as compared to severe disease.
  • It notes that, unvaccinated minority are still the major drivers of transmission.
  • However, currently available studies do not provide any credible evidence of substantially declining protection against severe covid-19 disease, which is main goal of vaccination.
