LONDON, April 7 (Reuters) - Blood clot side effects from the
AstraZeneca COVID-19 vaccine are serious but vanishingly rare,
England's deputy Chief Medical Officer Jonathan Van-Tam said on
Wednesday.
"My final cautionary point for you is that this is a
vanishingly rare, but sadly, quite serious adverse event, but it
is vanishingly rare, and you can't pick these kinds of things up
until you have literally deployed tens of millions of doses of
vaccine," he told a news conference.
