Earlier, UK Health Secretary Sajid Javid said his Government will “throw everything at” the Covid booster programme to tackle Omicron

Sadly, at least one patient has been confirmed to have died with Omicron,” Johnson, who on Sunday warned of a “tidal wave” of infection from the mutation, told reporters.

Speaking during a visit to a vaccination clinic near Paddington in west London, the British Prime Minister said: “Sadly, yes, Omicron is producing hospitalisations and sadly at least one patient has been confirmed to have died with Omicron.

“So I think the idea that this is somehow a milder version of the virus, I think that’s something we need to set on one side and just recognise the sheer pace at which it accelerates through the population. So the best thing we can do is all get our boosters.” 

It came after UK Health Secretary Sajid Javid said his Government will “throw everything at” the booster programme to tackle Omicron.
