According to a new study conducted by the Indian Council of Medical Research (ICMR), patients who suffered breakthrough Covid-19 infection after two doses of a vaccination had fewer hospitalizations (9.8 percent) and deaths (0.4%). According to the findings, the Delta variation was implicated in the majority of clinical instances of breakthrough infection.
“During March to June 2021, India has experienced a deadly second wave of Covid-19 with an increased number of post-vaccination breakthrough infections reported across the country. To understand the possible reason of these breakthroughs, we collected 677 clinical samples (throat swab/ nasal swabs) of individuals who had received two doses (n=592) and one dose (n=85) of vaccines (Covishield and Covaxin,) and tested positive for Covid-19, from 17 states/Union Territories of country,” says the preprint study.
A breakthrough case is when a fully vaccinated person later (more than 14 days after) gets the disease that the inoculation was for.
