The Pfizer/BioNTech vaccine, Oxford/AstraZeneca jab and now Moderna vaccine are being offered across the UK.
However, those aged 30 and under are now unlikely to receive the AstraZeneca jab, following concerns around blood clots.

In all, the Government said almost 40 million doses of the vaccine have been delivered since the rollout began in December, including 32 million first jabs and more than seven million second doses.
In a statement, Prime Minister Boris Johnson said they remained on course to offer a first jab to all adults in the UK by the end of July.
He said: “We have now passed another hugely significant milestone in our vaccine programme by offering jabs to everyone in the nine highest risk groups.
All you need to do is enter your age, whether you have any health concerns or are pregnant, and you will be given a likely date for receiving the jab.
For example, at the time of writing a 35-year-old with no existing health issues is expected to receive their first vaccine between May 14 and June 6.
Similarly, a 26-year-old with no health concerns is expected to receive their first dose between June 20 and August 1.
When it is your turn to be vaccinated, the NHS will get in touch via text, letter or phone call.
Vaccines minister Nadhim Zahawi said the newly available Modern vaccines will be deployed widely “around the third week of April” with “more volume” expected by May.
Mr Zahawi said on April 7 more Pfizer and Oxford/AstraZeneca doses will also arrive.
He added the Janssen vaccine is “coming through as well”.
He said: “So I am confident that we will be able to meet our target of mid-April offering the vaccine to all over-50s and then at the end of July offering the vaccine to all adults.”
