Nasal flu vaccination at GP surgery for 2 to 3 yr olds

[tigger001]

So I wasn't aware this was a thing. My GPs surgery have just contacted me informing me of the Nasal flu vaccine my son will have, she has made an appointment for him on Saturday.

Has anyone had this ?

I can't find any damaging info on it, but just wanted to see others experiences or opinions ?

Yes, my youngest has it every year. It's just a very tiny puff of vapour up the nose. Doesn't even make them cough.
Mine hasn't had any side effects either.

Children have had it for years. My nearly 7 year old has had it since she was 2. I would get it for my younger one but he isn't 2 til February. Nothing damaging about it. That's what clinical trials are for. But the flu is awful.
