Following the alarms about blood clots after vaccination with Astra Zeneca's vaccine, there have been requests among anxious elderly people to opt out of the vaccine - to choose another one instead.

Not possible, says Anders Tegnell.

- It is impossible.

There may not be all vaccines in all places all the time.

Then you probably have to wait.

I have a hard time believing that we can have that kind of offer until later this autumn.

If you wait, you take a clear risk that you will be infected instead, says Anders Tegnell in tonight's Aktuelt.
