Regular booster vaccines are the future in battle with COVID, expert says

Sharon Peacock, who heads COVID-19 Genomics UK (COG-UK) which has sequenced half of all the novel coronavirus genomes so far mapped globally, said international cooperation was needed in the “cat and mouse” battle with the virus

“We have to appreciate that we were always going to have to have booster doses; immunity to coronavirus doesn’t last forever,” Peacock told Reuters at the non-profit Wellcome Sanger Institute’s 55-acre campus outside Cambridge.

“We already are tweaking the vaccines to deal with what the virus is doing in terms of evolution – so there are variants arising that have a combination of increased transmissibility and an ability to partially evade our immune response,” she said.
