I have to admit the current corona situation feeling much less pressing hasn't made me get my booster yet

I keep planning on going "this Saturday" but then I figure "I'll do it next week." I don't have any plans requiring a booster shot, I'm still working from home, masks are still required in stores, I don't feel any urgency to get it.
Pfizer is still being rationed here - it's only available for people under 30, people who are pregnant or for people getting the 2nd shot who had Pfizer as their first shot. I know there's not much difference between Pfizer and Moderna but with emetophobia the tiny bit higher incidence of nauseau with Moderna is an extra hurdle to take to get the Moderna shot (and yes, I am perfectly aware I'm being irrational but that's the thing with phobias

)
I don't really get why they're still rationing it when there's fewer and fewer people getting a vaccination - surely they should have enough doses to give people a choice?
