What vaccines should I consider before traveling to Thailand for a month?

Not dengue fever. You can’t get that one until you’ve had dengue once. Get a flu shot, a Covid shot, DPT and a Japanese encephalitis shot. Stay away from monkeys and dogs once you get here and you won’t need the rabies shots.

All of them

Dengue fever and tetanus.

All

Think there’s a list on the NHS website that covers this

If a street dog bit you in Thailand please go within one hour to the next doctor or hospital

Brain vaccine...

The best thing you can do is to keep mosquitos off of you while you're here. Dengue fever is pretty horrible. There is no vaccine for it either. My husband and I have both had it once. But we've lived here for 8 years now.

None . Just personal hygiene and you'll be good

Tetanus is about all i care about over there

None other than some stomach stuff

Hepatitis which you may have got the shot if you are younger

Dukoral to prevent travellers diarrhea

Just what you'd have at home. Like checking your tetanus is up to date.

For a month, you don't really need to worry about it. Most of the vaccines that might be recommended are generally only recommended if you'll be spending significant time in SE Asia or if you'll be doing some very specific activities.

If you are from a few select countries in Africa, there is a required Yellow Fever vaccine, but that likely doesn't apply to you.

So in my opinion you're fine. The only thing I might recommend is the flu vaccine if you haven't gotten it this year. I know 3 friends in Bangkok who had the flu last week, including one who went to the hospital. But I'd just follow your doctor's normal advice for flu vaccines and vaccines in general.
