Scientists test the risks and rewards of mixing Covid shots

Oxford scientists are expanding efforts to test whether two different Covid-19 vaccines can be combined, after some European countries worried by rare side effects with the Oxford/AstraZeneca jab started offering other vaccines as second shots.

The group of over-50s will either receive a second dose of the same vaccine or get a dose of the Moderna or Novavax shots.
