I'm a retired RN of 37 years but I don't have an answer for you. In my experience, at least here in the states, a Tetanus is a single injection not combined with any other vaccines. I would only be assuming that would be the same in Jamaica. The best answer would be to see if you can get any info from the doc in Negril. Good luck! You might be able to check with another physician in Negril and see what the standard protocol is in Jamaica.
