uk Almost half of UK COVID infections are in people who are at least partly vaccinated Almost half of COVID-19 cases in the UK are among people who are partly or fully vaccinated people, according to data from a large study. The finding came from the ZOE COVID Study run by King's College London. It uses information logged daily by over a million people to predict COVID-19 trends As of July 15, an estimated 17,581 new daily UK cases of COVID-19 were in unvaccinated people, the study authors said in a press release on Thursday. That compares to an estimated 15,537 new COVID-19 cases in people who had at least one dose of the vaccine, which is about 47% of all cases.
