Vaccines for COVID-19

Updated 30 December 2021

Vaccines in use in the United Kingdom

The first vaccine to help protect us from COVID-19 was approved on 02 December 2020. Some people with PSC have been prioritised to receive the vaccine early.


Pharmaceutical companies have been running clinical trials to evaluate the safety and efficacy (effectiveness) of COVID-19 vaccine across the world. They have been able to gather the necessary data in record time by adopting special trial designs.

Next, the body that regulates medicines, the MHRA, reviews information from these trials to decide if they are safe and effective enough to be used. The MHRA evaluates the data rigorously for quality, safety and effectiveness to reach an independent, scientifically robust opinion. The data must include results from lab and clinical trials in humans; manufacturing and quality controls, product sampling, and testing of the final product.

The MHRA is globally recognised for requiring the highest standards of safety, quality and effectiveness for any vaccine.
