As you may know, second bivalent boosters are currently only approved for people 65+ or whom are immune compromised. As you also may know, the vast majority of the booster's effect only lasts about three months.
I scheduled it online- I just ticked yes for the first box for "are you taking any meds that may compromise your immune system." The same question is repeated a second time on another page but answering yes here requires you to enter information about the medication, so I entered no and it let me schedule it anyway.
If I was asked in person I was just going to say I use a steroid nasal spray (i don't) but the dude didn't say anything. Seemed happy to have someone getting a vax if anything.
When I took virology many years before Covid19 hit and all that extra anti-vax noise, the teaching assistant would describe vaccines as 'customs for your immune system', it amused me so much it stuck with me this long. I'm getting due myself next month or so.
