That was a genuinely worrying press conference, particularly the doubts on the efficacy of the jab.
But he says there is "more concern" about the susceptibility of the South African and Brazilian variants to vaccinations.
There are concerns about this, he says, adding that it is being studied at laboratories around the world.
The Daily Telegraph's Gordon Raynor raises a video he says has been posted by Health Secretary Matt Hancock aimed at travel agents, suggesting the South African variant is 50% less susceptible to vaccines than the original strain of the virus.
He asks whether this is correct and, if so, whether it will affect the government's approach to whether to tighten UK border controls.
The PM runs through the measures that the UK has in place, including the ban on direct flights from South Africa and "rigorous" obligations for people entering the UK in terms of quarantine and tests.
But he suggests "we may need to go further to protect our borders", saying the massive progress the UK is making in terms of vaccinations cannot be undermined.
If that is true about the new strains, I think the vaccines being the light at the end of the tunnel, might just be a false dawn.
A more deadly strain of the vaccine but the Tory Death Cutl say the lockdown we have is ok.
Is the penny beginning to drop yet?

I thought viruses become less dangerous when they mutate?
maybe i'm being thick but i really didn't get Vallance. The new variant doesn't cause any more deaths if you go into hospital with COVID, but is more fatal.
I really didn't understand that at all
I don't understand that once all the elderly and vulnerable have been vaccinated we won't be able to go back to something like more normal life.
Because it's public relations (PR) bull on the vaccine number roll. This PR bullsh*te is just the one jab that is not what the Vaccine manufactures suggest in best practice, terrible. It's like we are in the afterlife with Trump in his tower...
I gave up watching those handmaidens in November when they stood gormless and allowed Johnson promise 5 day Christmas... Principled by science they are not.You clearly didnt watch the briefing.
Or if you did, you made a cuppa when that was explained. By a scientist.

Up to employers to start following the guidance which - word for word - is the same as it was in March, too?
Not gonna argue the toss on Johnson.
But Whitty explained quite clearly that the single dose to max out the numbers to get SOME protection is far better at suppressing a spread than 2 doses into half the number.
