I had that last year and will have the same next week. My only problem was persuading the nurse to do both in the same arm so that I could sleep on the other side. She said they normally do one in each arm.
I have always had them together. I usually get a mild reaction to the Covid jab. A recent US study found that it was positive if people had a reaction because it meant our antibodies were building a robust immune response and offered us extra protection.
My partner and I did, he had no side effects at all, but I did. My partner will have the same again. I will not. I think everyone is different, you can try it but if you find you get side effects you know not to fo the same next time.
On impulse, I’ve just booked a flu and covid jab to be done at same time. Now I’m thinking about it I’m wondering what if any side effects might happen. Has anyone had these together and how did you feel after. Thank you for advice.
