Does paracetamol reduce vaccination efficiency?

[Rufus27]

DP had his vaccination yesterday and has since felt rough - chills, aches, headache etc. A neighbour, who’s a nurse practitioner, has told him to try not to take paracetamol as it will reduce the effectiveness of the vaccine. Does anyone know if this is true? Surely, if it were true, it would be far more widely known? His view is that, as she’s a nurse, it must be right. I’m not convinced. Does anyone know for sure?

Prophylactic paracetamol is not generally advised, so she's quite right.
It can be given for side effects afterwards if necessary and must always be given to babies for Men B as part of their primary immunisations.
Practice nurse.

I hope not ,I have to take paracetamol and codeine to allow me to walk into town, so I had to take it before my first jab.
