Aria,
I got the flu and COVID vaccines yesterday. I'm having the usual 24hr. aches and headaches. As a PH patient you should absolutely get the vaccines, including RSV if you haven't had one yet.
We're not on the same meds but it doesn't matter .

I'm also on tadalafil and had my flu shot this week. Doing good. I am tired, that's it.

I am on both medications. I had a flu shot a couple of weeks ago and no problems whatsoever.

Thank you for your replies. I made the flu vaccine and did not have any side effects.

My lung dictor gave me my flu shot and I ask about the rsv and he said that it wS up to me but did not see a big difference e with that shot
