EU governments agreed to share compensation costs only if unexpected side-effects were discovered after the AstraZeneca vaccine was approved, with the company paying legal costs only up to a certain amount. The deal with AstraZeneca was negotiated before late-stage trials of its vaccine were put on hold this month after a British volunteer developed neurological symptoms. Trials have started again in the UK but not in the US. Side-effects after a drug has been given regulatory approval do not usually occur. How is Boris Johnson handling the coronavirus crisis?
