In this case, my quoted text was from the European Medical Agency so I don’t really understand your comment.
If someone lived on their own, and rarely went out then the chances of catching the current year’s flu would be quite slim.
Comparing that with the common side-effects of the vaccine of muscle or joint pain, headache, chills, swollen lymph nodes, nausea, vomiting, and fever lasting three days, especially if they weren’t in a high-risk group, they may well chose not to have the vaccine.
Mine was a reply to a different post. Regarding your last post. Yes, everyone should make their own decision based on their own circumstances. The advice from medical sources is generally fairly consistent. Vaccination is highly recommended for my age group. Last year I got separate vaccinations because the single one was not available here and my GP advised a time delay between the two, presumably to minimise side effects. I am not sure how it relates to people who lead a fairly isolated life. Any challenge to their immune system, from a vaccination or pathogen, may or may not evoke an unusual response.
For the past two years (or three maybe?), my mum in the UK has had the flu and Covid shot simultaneously but one in each arm. She’s never has had any side effects from either but she’s a tough old bird.
I‘ve had both on the same day, one in each arm. Did it last year and I’ll do it again when my gp has it available. I had a bit of a sore arm, but just for a day. I forget which one hurt.
