you may think they are poison but I bet you're glad WE had smallpox vaccines to eradicate it, so you never needed one. No need to thank me. Oh and we had the polio vaccine so you didn't need one. . But now people like you keep trying to scare folk, and the polio risk is back. Not for me, I'm vaccinated against dying or being paralysed from it 😉.
They are quite cheap to get in Thailand. But in UK some are free. It all depends on what you've had previously, if they need updating and if you want any added protection. Only you and your Dr can decide that. I'm having my HepA because it's out of date. But that's because someone's recently returned to UK infected and extremely sick. I've decided to get mine updated.
those are cheap prices. I've just gone through my vaccination record to see what has lapsed and need boosters. HepA required an argument with my GP clinic to get him to agree to me getting it.
