Britain Makes Final Preparations for First Round of COVID-19 Vaccinations VOA News Britain is on the eve of launching a COVID-19 vaccination campaign. Staffers with the nation's National Health Service, nursing home residents and their caregivers on Tuesday will begin to receive the first of two doses of a vaccine jointly developed by U.S.-based pharmaceutical giant Pfizer and Germany's BioNTech. The initiative will start nearly a week after the government's medical regulatory agency granted emergency approval for the vaccine, making Britain the first western nation ready to begin mass inoculations. The approval came weeks after Pfizer announced the vaccine had been shown to be over 90% effective after its final, widespread clinical trial. .
