The Covid-19 vaccines have not only been tested on healthy people as claimed – Full Fact


28 May 2021

What was claimed

People who were undergoing chemotherapy have been told that they should not receive vaccines, and should stay away from people who had received vaccines, and now because of Covid-19 this has all changed.

Our verdict

People who are immunosuppressed are advised not to have live vaccinations and not to be in close contact with people who have received certain live vaccinations, but the Covid-19 vaccines in use in the UK are not live vaccines and people undergoing chemotherapy have been prioritised to receive them.

What was claimed

The Covid-19 vaccine was only tested on completely healthy people.

Our verdict

Incorrect. The trials of the Covid-19 vaccines did include groups of people with certain medical conditions. We are also finding out more about this through post authorisation monitoring.

What was claimed

The Covid-19 vaccines have been authorised on an emergency licence, because they are still in clinical trials.

Our verdict

Two of the vaccines have received temporary authorisation, and the Moderna vaccine has been issued conditional marketing authorisation.

These classifications are regulatory tools to allow approval at the earliest time possible during an emergency situation, as soon as there is robust data to show that the benefits outweigh the risks.
