Hey I just wanted to say good on you. I know some people are really quite scared of the vaccine and given how much misinformation and even just conflicting information there is, i totally understand it. However you were an adult about it, you informed yourself and then changed your mind based on an informed decision so on behalf of everyone else I wanted to say thank you.
FWIW my first Pfizer shot was scary too, but i got jabbed and aside from a sore arm for a couple days I was completely fine.
Second one is next week so i'll see how it goes - but I reckon even if i cop the 24 hours of fever/headache from it - it's still millions of times better than getting covid :)
Good luck for your jabs!
