ICMR study has good news for fully vaccinated peopleNew Delhi: A preliminary report on breakthrough infections based on a small sample size of 361, collected by “passive and voluntary” reporting from healthcare centres in Odisha, found 274 were Covid positive after being fully vaccinated. These 274 individuals had also completed the 14-day window post full vaccination by which time antibodies are expected to develop.

The samples were collected from healthcare centres in Odisha between March 1 to 10 June. Those who were not fully vaccinated had recieved one dose. While the samples were then sent for laboratory confirmation, there was a likelihood of these individu-als being Covid positive given the prevalence of the second wave at the point in time. Given the concerns over infections, it can be assumed that people visited healthcare facilities only if they felt the need to do so.

While a significant proportion of laboratory-confirmed Covid-19 cases were fully vaccinated, over 83% of them showed symptoms and only 9.9% of the symptomatic breakthrough infections required hospitalisation, the study conducted by the Indian Council of Medical Research shows, offering evidence that vaccines protect against severe illness.

Out of 361 samples, 76% were found to be positive after 14 days of receiving complete doses of the vaccines. The study is yet to be peer-reviewed. The number of hospitalisations was low and only one death was reported out of the 27 hospitalised individuals. The seropositivity in individuals receiving Covishield (96.7%) was higher than in Covaxin (77.1%).
