Some cases of dol variete were reported in India during the second wave and cases are being found in some states now.


The report cites other studies indicating a reduction in neutralization titers between Covashield and Covaxin doses after infection with the delta variant. Jerome Thangaraj, a scientist at the National Institute of Epidemiology involved in the study, said that since the sample size was small, he did not include reinfection. Because their numbers were very small and it was not further classified whether people were infected after vaccination. However, the proportion of patients with increased mortality due to severe disease was lower in the vaccinated groups.
