Covid-19 vaccines are estimated to have prevented nearly 1.98 crore deaths worldwide — out of a potential 3.14 crore deaths — in the first year of the vaccine programme, a new modelling study has found.

According to a June 21 report of Indian SARS-CoV-2 Consortium on Genomics (INSACOG), 44 samples from Bengaluru sent for genome sequencing between June 2 and June 9 were found to be infected with BA.3, BA.4 and BA.5 sub-lineages of Covid variant Omicron. This development comes after a recent sewage surveillance report had also shown the presence of BA.4 and BA.5 sub-lineages of Omicron in the city. On the advice of the Covid technical advisory committee (TAC), the health department on June 7 set up a sewage surveillance appraisal committee headed by the committee’s chairman M K Sudarshan.
