Sir Patrick Vallance said scientists are looking at whether it will be possible to combine different Covid-19 vaccines to boost the results.
“It’s a pretty standard way of boosting the immune system, so-called heterologous prime-boost, ” said the Government’s chief scientific adviser.
“What it means is that you give one vaccine to get the immune system triggered up and another one to then boost it further with a different vaccine – that’s an established way of getting the immune system geed up.
“But that needs to be looked at – you can’t assume that it will work. It needs to be tested properly, and that’s one of the things about all of these vaccines and all of the clinical trials of medicines is you need to do the trials properly, you need to make sure you test these things.”

Tributes have been paid to an emergency department nurse who died after testing positive for Covid-19.

Emergency department matron Anna Bell said that Mr Healey’s colleagues referred to him as a “true gentleman” who “always had a smile”.
“Rob was overwhelmingly lovely, a magnificent man. He was everything a nurse should be,” she said.
