What is going on in the UK? I keep seeing that they've given people the first part of the vaccine, but there are problems with getting the second dose.
It’s deliberate. If I understand correctly, the first jab of the Pfizer vaccine is something like 90% efficacy , while the booster makes it up to 95% and provide longer immunity.
EDIT: Sorry, that number is BS. It’s much lower.
As we have the new much more transmissible variant running rampant in the country, they are delaying the booster to give as many people the initial shot as possible. Hopefully they don’t delay enough to undermine the vaccine in the long term.
The rest of the world really doesn’t want this variant. You should all stop anyone from the UK entering your countries for a few months.
