All of a sudden (yesterday apparently) there blossomed on the major news outlets an admonition not to take either Tylenol or Advil prior to and or immediately after Covid-19 vaccination.
The logic articulated is that their reduction of a fever or inflammation attenuates the intended immune response.
This is surprising on several levels. I have received several vaccinations in my adult life - flu, both shingles, both pneumonia - and never has this reservation been mentioned. Actually the opposite.
Separately, as a rank amateur, I wonder which way the logic works. I would think in that fever and inflammation are part of the body's defence mechanism, so that limiting them would allow vaccine antigens more "running room," thereby giving a better immune response.
So my questions are:
Is there a validity in the notion of not taking either or both of the medications coincident with a vaccination in general?
Is there a distinction in this context between acetaminophen and ibuprofen?
Is there something specific to Covid-19 vaccinations that gives the admonition bearing?
What if someone has already been vaccinated before this purported warning became publicized, are they in limbo?
