I was lucky to get Pfizer, was the only choice allowed when I booked before these current outbreaks - which I did expect to happen sooner or later. I'm in and out of hospital at times (twice in past year, first time just before we had a snap lockdown) so I went ahead and got it, although I'm not happy about others not having the same choice.
Can tell you though that second dose of this mRNA is kicking my butt one week later and I'm just starting to get it sorted out. This is like no other vaccine I have ever taken and sure does have potential side effects that linger even if not TTS. I'm glad I took it and think it's a rare reaction but I doubt I will take it again in future. If I need a booster I hope Novavax is available.
