Infections after the Covid-19 vaccination.

About:

  • The Indian Council of Medical Research (ICMR) has reported that around two to four of 10,000 people given two doses of the COVID-19 vaccine have tested positive for the disease
  • Such cases are referred to as “breakthrough” infections, indicating that the virus has been able to break through the defences created by the vaccine.
  • Experts said it is possible that mutated variants of coronavirus infection may be finding ways of escaping the vaccine.
  • Phase 3 clinical trials conducted before vaccines were approved showed a fairly constant proportion of infections among those vaccinated.
     
  • In the AstraZeneca trial, for instance, 30 out of 5,807 vaccinated — about 0.5% — were symptomatic and tested positive 14 days after the second shot.
