Seasonal booster doses

Seasonal boosters are recommended for some people at higher risk of COVID-19 illness. The Spring COVID-19 booster programme has now ended. We will update this page with more information on seasonal COVID-19 booster recommendations when they are available.

Booster doses while pregnant

You can get a COVID-19 booster once during pregnancy. The best time to get your booster dose is between 20 and 34 weeks. But you can get it at any stage of pregnancy. Wait 6 months since your last COVID-19 vaccine or COVID-19 infection before getting a booster.

If it has been more than 12 months since you had a COVID-19 vaccine or COVID-19 infection, you may be offered a booster dose earlier in your pregnancy.

If you have a weak immune system

You usually only need one booster dose in pregnancy. But if you have a weak immune system, you can get a second booster 6 months after your last COVID-19 vaccine or infection.

If you have not had any COVID-19 vaccines yet

If you have not had any COVID-19 vaccines, you can get your first round of COVID-19 vaccination at any stage of your pregnancy. This is a single dose, unless you have a weak immune system.

Booster dose safety

Many countries have given multiple doses of COVID-19 vaccines. There have not been any unexpected safety concerns so far. The safety of the vaccines continues to be monitored by the European Medicines Agency (EMA). The side effects of the adapted Pfizer/BioNTech vaccines are similar to the original vaccines. The most regularly reported side effects are headache, fever, and tiredness.

Myocarditis and pericarditis are inflammatory heart conditions and are very rare risks of mRNA vaccines. These rare side effects are more common in men under the age of 30 years after their second primary vaccine dose. The risk of these side effects appears to be lower after the first booster.
