Q and A


Which vaccines against COVID-19 are being used in the UK?


The first vaccine that was approved in the UK is called BNT162b2 (tozinameran). The trade name is Comirnaty.

BNT162b2 is made by Pfizer/BioNTech. It was approved in the UK on 2 December, in the US on 12 December and in the EU on 21 December 2020.

On 8 January 2021, a second similar vaccine, developed by Moderna/NIH was approved in the UK. However, this is unlikely to be widely available until March/April 2021. The Moderna was approved in the US on 18 December 2020. The code name for this vaccine is mRNA-1273. It was approved in Europe on 6 January.

On 30 December 2020, the UK approved the vaccine from Oxford University and AstraZeneca. This is called ChAdOx1 (from Chimp Adenovirus Oxford). It also has the code name AZD1222.

Other vaccines are being used in UK studies (see later below). These include a vaccine from Janssen that might only need one dose (JNJ-78436725), and a self-amplifying ribonucleic acid (saRNA) vaccine at UCL. As new vaccines are approved we will add them to this page.

The PROVENT and STORM CHASER studies are looking at using a monoclonal antibody (AZD7442) for people who might not benefit from vaccines. GSK is also studying a monoclonal antibody (VIR-7831) in early infection.

This is one of more than 45 questions about COVID vaccines. It was produced by and for people living with HIV.
