The United Kingdom on Wednesday gave emergency approval to Pfizer and BioNTech's COVID-19 vaccine, becoming the first Western country to allow mass immunization against the viral disease. The vaccine, which has been shown to have 95% efficacy in late-stage clinical trials, will be made available across the country for at-risk groups starting next week. The UK has pre-ordered 40 million doses of the vaccine.
