1 in 10 people who have the COVID vaccine get a sore arm for a few days. Now if you’re one of those people and you’ve got a sore arm right now then you’ve found the right video because we’re going to discuss what you can do to help get rid of that sore aching arm, and I feel you because I had the same thing and loads of people I know did too!

I do have a ton of other useful videos about the COVID 19 vaccines as well as the seasonal flu vaccines available on my channel; feel free to check those out too. Before I cover how to get rid of a sore arm after a vaccine, let’s touch on why we get one in the first place.


The introduction of the vaccine into the body through a needle causes a minute injury to your arm muscle. This injury triggers inflammation at the injection site, and your body then goes about mounting an immune response which involves your white blood cells.

Your arm (i.e. where you’ve been injected) is where those white blood cells which have been activated as part of your immune response; end up. Put very simply, this inflammation is your body’s way of defending itself against things that it thinks are harmful. It’s exactly the same as what happens when you get hurt, and is a clever way of your body trying to protect and heal itself.

We know that inflammation is happening at the site of injection when we experience pain, sometimes redness, heat and swelling. So actually, a sore arm makes perfect sense and is nothing to be too concerned about at all, so please do not panic! Believe it or not, it’s great news as it means the vaccine is doing exactly what it’s supposed to do. There will of course be some people who don’t feel any pain at all - and I’m afraid that they are just the lucky ones.

If however you do get a sore arm, it’s not likely to last more than a few days at most because that’s how long it takes to recover from the needle injury, and that’s when your body is busy mounting it’s immune response. So, now that you have an understanding of why we get a sore arm after we’ve had a vaccine, let’s delve into what we can do about it.


The vast majority of people won’t experience any concerning side effects, however, you should seek medical advice: A) you notice a rash at any point, B) you’re finding that the soreness seems to be getting worse, not better within 24 hours of the jab, C) your arm is so painful that you can’t even touch it or move it. D) If the soreness doesn’t seem to be going away after a week.


The main symptoms of coronavirus (COVID-19) are:

a high temperature – this means you feel hot to touch on your chest or back (you do not need to measure your temperature)

a new, continuous cough – this means coughing a lot for more than an hour, or 3 or more coughing episodes in 24 hours (if you usually have a cough, it may be worse than usual)

a loss or change to your sense of smell or taste – this means you've noticed you cannot smell or taste anything, or things smell or taste different to normal

If you have any of the main symptoms of COVID-19, even if they're mild:

Get a PCR test (test that is sent to a lab) to check if you have COVID-19 as soon as possible.

Stay at home and do not have visitors (self-isolate) until you get your test result – only leave your home to have a test. Check if people you live with need to self-isolate.
