Paediatric dose of vaccine for 11 year old

[AquabeadsEverywhere]

Someone asked this on another thread but there were no answers. Googling doesn't appear to answer my Q either.

I'm going to get DS age 11.5 vaccinated. He's not 12 until late august. He was only a little poorly with covid but I feel it's the sensible thing to do.

Given he's reasonably tall, maybe 5' 4", should I wait until he is eligible for the adult dose? Or can I ask at the vaccination centre and they apply common sense? If they're allowed obviously.

I'm not sure what the best course of action is so if anyone can help it would be appreciated.

When did he have covid last?

I doubt they'll be able to give him the adult dose until his 12 as it's not licensed

If he was only a little bit poorly then what's the point? Hardly any children actually get very.ill and adults who wanted it are all vaccinated!

They won't give an adult dose to a tall 11 year old.
I have a small 12 y o and I would have preferred him to have the kids 1/3 dose, but it's not an option.

The “adult” Pfizer is out licensed for 12+ year olds, so they won’t give it to him, no matter his height/weight. So your choices are either to get him vaccinated now with the paediatric version, or after he’s 12 with the adult version.

• is NOT licensed

What does he weigh?

Any medics please correct me if I'm wrong, but I believe peadiatric vaccine doses are not reduced because children have a lower body mass. They don't have the same mechanism of action as drugs (like paracetmol or propofol, of which dose is calculated by weight).

It's to do with how an immature immune system responds to foreign antigens, and therefore a child being big for their age shouldn't really make a difference in this instance.

Vet here- a 2kg chihuahua and a 100kg mastiff get the same dose. All to do with age/ immune system development, nothing to do with body weight.

The reason I'm getting him vaccinated is I understood it reduced transmission rates to others so I would be doing it as a society good measure rather than I think he should have it to prevent serious illness.

I have no idea how much he weighs.

He had covid in October 2021 alongside most of his class.

So perhaps a paediatric dose would be sensible to not overload his system then? The 12 year olds who have had it have mostly been fine as far as I know.
