Had a Heptatiis B vaccination for a Feb 2013 mission trip to Honduras where I would be up in the mountains helping to pour cement for floors, etc. NOW I have scheduled a pleasure trip with a tour group to visit Lima, Cuzco, Macchu Piccu, Puna and will include a home dinner with a selcted family. Do I need to get another hepatitis B shot? How long is the shot protection good for???
Hi, thanks for using Chat Doctor If you received the full course of the vaccine then you do not need to be re vaccinated because you would be fully protected. The full course is 3 vaccines. If you only received one dose of the vaccine then you should consider repeating the course because it is not complete, and you would not be immune. I hope this helps
