COVID-19 vaccination program commences in the UK to combat the virus.

The UK initiated its COVID-19 vaccination program, starting with a 90-year-old woman becoming the first recipient outside of clinical trials. The first approved vaccine was developed by Pfizer and BioNTech. The UK was the first Western country to begin a mass vaccination campaign against the virus. The government prioritized vulnerable groups and healthcare workers in the initial phase. The vaccine required two doses, administered a few weeks apart, to achieve maximum effectiveness. The start of the vaccination program marked a significant milestone in the fight against the global pandemic. #UK #COVID19 #VaccinationProgram #PfizerBioNTech #HealthcareWorkers.
