AstraZeneca’s and Pfizer’s vaccines are safe to be used as booster shots – MHRA Update

UK medicines regulator has declared that booster jabs can be used with the Pfizer/BioNTech or AstraZeneca vaccines.

The Pfizer jab is being tested in a clinical trial alongside AstraZeneca Moderna, Novavax and Janssen from Johnson & Johnson. It costs PS19.3million.

The study will examine whether people who received two doses AstraZeneca might get more from the third dose of Pfizer.

According to the new MHRA guidelines, boosters from Pfizer can now be administered to any person regardless of previous doses.

AstraZeneca boosters can only be administered to people who have had AstraZeneca.


Dr June Raine, MHRA chief executive, said: “We are committed to getting safe and effective vaccines to the UK public.

“This means ensuring that existing COVID-19 can continue to be used in the most effective way possible.

We know from experience that immunity can decline after the first vaccination.

I am happy to confirm that both AstraZeneca and Pfizer have COVID-19 vaccines which can be used safely and effectively as booster doses.

According to the Centers for Disease Control and Prevention, the booster shots are designed to protect against severe illnesses, hospitalisations, and even death from the Delta virus.

Public health professionals are beginning to notice a decrease in protection from mild and moderate diseases with the Delta version.

To help protect against the effects of the flu, booster shots have been developed to give protection for those who were vaccinated.

Dr Raine said, “This regulatory change is important because it provides additional options for the vaccine programme, which has already saved thousands of lives.”

The JVCI will advise whether booster jabs are given, and, if so which vaccines to use.

We have a safety surveillance plan to monitor the safety of all UK approved Covid-19 vaccines. This surveillance will also include booster jabs.

A spokeswoman for the Department of Health and Social Care stated that they are continuing to plan an autumn booster program to protect those most at risk from Covid-19.

The final recommendation of the independent JCVI will determine the content and format of any booster program, which may include recommendations for vaccines.
