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?
