Health Advisories

I will be travelling, for the first time, from the USA. The United State Center for Disease Control mentions a number of “possible” risks like Hepatitus A, Hep B, Japanese encephalitus, but nothing mandatory. Is anyone aware of anything different?

I’m going to Taiwan in 2 weeks and have opted to get the hep A and a tetanus injection on monday.
I opted out of hep B and jap E injections.
What did others do? I’m from the UK btw and going for 10 days.
