Wear a mask appropriately, wash your hands, and be safe! And mRNA based vaccines are heavily researched already (and freaking cool to me), but sorry you have go through a website TOS to get a vaccine... that does sound kinda dumb for accessibility. I can just walk into a pharmacy and ask for one the same day. Though I'm pretty sure I'm still signing a TOS on paper regardless, cause that's just kinda how risk/benefit works. Wish you all the best though and good luck!
