Hepatitis A is another common requirement. The rule is usually if you plan to stay within a resort you should be OK, but go off the beaten track and you should get jabbed up. That said, I�ve never know mosquitoes to be aware of perimeter fences.
My doctor does required jabs for free and recommended ones at a charge, which seems reasonable to me.
Your GP surgery will tell you what you need as they get updated info from the DOH. Some jabs needs to be a couple of weeks ahead of your travel date, so allow this time.
This site will help you, although T&C not mentioned directly.
