UK Abruptly Changes Guidance on Oxford/AstraZeneca Vaccine Amid Blood Clot Concerns

Strategic Insights

— 2 min read

The UK government has altered its vaccine guidance, recommending that people aged 18-29 be offered alternative jabs due to concerns over rare blood clots linked to the AstraZeneca vaccine. This move comes after the European Medicines Agency (EMA) said that there was a plausible link between the vaccine and rare blood clots in the brain. The UK's Joint Committee on Vaccination and Immunisation has advised against using the AstraZeneca vaccine for those under 30, opting instead for the BioNTech/Pfizer or Moderna jab. The decision is a significant course correction to the UK's vaccination program.
