Our Covid booster shot clinic at work is officially set for Friday morning. The infection control RN came to my office and discussed it with me and my coworker this afternoon [she's vaccinated, but, she wants to see her Mother & Stepfather this weekend, so, she's not getting the booster (it's not mandatory), because she doesn't want to feel sick from it...her life, her choice]. He had some interesting things to say that I didn't know:
1. The Pfizer vaccine has to he kept way below zero (like -80 CELSIUS I think he said), while the Moderna and Johnson & Johnson ones can be stored with normal refrigeration. Because of this, he believes Pfizer will be phased out in favor of the other two, over time, because it's more troublesome/costly to store.
2. While you can get a different booster brand than your original vaccination, results tend to be better if you stick with the same brand for your booster (i.e., you're less likely to feel ill). He got Pfizer (he didn't work at my facility yet when we did our Moderna vaccinations in January/February), so, he's not getting our Moderna booster on Friday and getting Pfizer elsewhere instead for that reason.
