AstraZeneca vaccine: How do you weigh up the risks and benefits? By Robert Cuffe Head of statistics


Based on the figures announced today by the UK medicines regulator, if 10 million imaginary people were given the AZ vaccine you might expect to see 40 of these clots - with about 10 clots having fatal consequences.


Ten deaths out of 10 million people vaccinated is a one-in-a-million chance.


That's roughly the same risk as being murdered in the next month or - if you get in a car and drive for 250 miles - the risk of you dying in a road accident on that journey.

Roughly 40 men and 100 women in our imaginary group of 10 million might expect to have one of these clots in any given year without vaccination, with more seen in younger people.

These clots happen more often to pregnant women or people taking female hormones.

In general, if you're on the pill the risk is about six times higher than if you're not.

So the risks of a clot for those taking a contraceptive pill seem, at first glance, to be in a similar ballpark to the risks potentially linked to the AZ vaccine, but we can't know for sure with the data we have.

While there's no simple number for everyone, for most people with a high risk of catching Covid or dying from Covid, the current data suggests very strongly "your chances of remaining alive and well will go up if you take the vaccine and will go down if you don't" as JCVI member Adam Finn explains.

But it does change for younger people.

England's Chief Medical Officer Prof Chris Whitty says: "The closer you get to someone who's right down at 20, and otherwise blameless in their health, the more you have to think through these really very rare side effects - the risk/benefits might get closer to parity."

比較は難しいようであるが、一千万の人がワクチンをうけたとして40人に血栓ができ、そのうち10人は死ぬが、ワクチンを射たなくても年間1000万人に男40人、女100人は血栓になっている、と。コロナにかかって死亡する率を考慮すると大抵の人にとっては、ワクチンをうったほうが死亡率が低いが、コロナにかかっても重症化率、死亡率が低い若者については話は別である、と。

アストラは欧州の動向を注視、スプートニクは性能いいわけだから、本当は日本も交渉していてよかった。
