Here, at LloydsPharmacy, we answer all your common questions on the side effects of the flu jab, plus watch our video to find out more about flu.
Can you have an allergic reaction from the flu jab (vaccine)?
It is rare, but allergic reactions can occur. Signs to look out for are hives, swelling, heart racing and difficulty breathing. If you’ve previously had an allergic reaction to a vaccine or you're allergic to egg, you might not be able to get the vaccine. Speak to our pharmacists to find out more.
Can I catch flu from the flu jab?
You can't catch the flu from the flu vaccination because it contains inactive particles of the flu virus. If you do get the flu after receiving your jab, it’s likely to be because the vaccination hasn’t become fully effective or you have picked up a different strain of the virus.
Can I still get flu if I've been vaccinated?
The flu jab is the best protection against this year’s flu virus. It won’t stop all strains of it. So, there’s still a small chance of catching the flu.
Does the flu vaccination protect me from coronavirus?
Getting the flu vaccination won’t protect you from the coronavirus as it is a different virus, and a vaccine for it is currently being made available. However, The World Health Organization (WHO) recommends we all get the flu vaccine each year to help prevent the flu and keep you and your family healthy all winter long.
Does the flu jab make you ill?
It is a common misconception that the flu jab gives you the flu, but minor reactions of flu-like symptoms including mild fever and tiredness are reported by some patients.
Does the flu jab make your arm sore?
A sore arm after any vaccination is common, and the pain comes from the muscle where the injection was given. A sore arm is a good sign as your body is responding to the vaccine.
Can the flu vaccine make you tired?
Most people feel fine after a flu jab, but some people do report feeling tired a day or two after receiving the vaccination.
Is fatigue one of the side effects of the flu jab?
When you get vaccinated the antibodies in your system are fighting the bacteria in the vaccine to make you immune, and feeling mild fatigue and tiredness is completely normal.

Will the flu jab give me a cold?

Can I get the flu jab if I am sick?

How long does it take before I am protected with the flu vaccine?
