Shots and Malaria Medicine

I got my shots today for Hepatitis A and B. I had tried to get the last week but the medical office at school was closed last week and I figured I could procrastinate before that. Then at last weeks orientation for my trip to Central America I found out that I needed to start taking my a week before we left. So I took the first Malaria pill yesterday and need to avoid all contact with mosquitoes for the first 2 days. Though what maybe equally if not more challenging will be avoiding eating fecal matter for the first week. Because my Hepatitis A shot doesn't start working for two weeks.
