Whilst the vaccines have been developed quickly, they have been extensively tested. The UK medicines regulator (MHRA) and the Joint Committee on Vaccinations and Immunisations (JCVI) have stated that the approved vaccines are safe and offer a high level of protection against becoming severely unwell with COVID-19.
The vaccine you receive will be determined by the available stocks in your area, and you will not get a choice about which vaccine you receive. However, if you suffer from severe allergies you should speak to a healthcare professional via contact details provided when you are given your appointment (or to your GP) as the MHRA has advised against giving the Pfizer vaccine to people with a significant history of allergic reactions to medicines, vaccines or food.
When you receive the vaccine, you may experience some side effects that are common to other vaccines, such as the one for flu. These are:
• A sore arm, particularly in the area you had your injection
• Tiredness
• Headache
• General aches or mild flu-like symptoms
• Swollen glands (this only affects a small number of people)
If you do experience any of these side effects, they shouldn’t last too long – they normally pass within a week. But if they don’t clear up or you start to feel worse, you should call NHS 111 Wales to describe your symptoms and let them know you’ve had the vaccine so they can advise you.
Any side effects you experience can also be reported to the Medicines and Healthcare products Regulatory Agency's (MHRA) Yellow Card Scheme.
