The current vaccine is Tdap (Boostrix®, Adacel®), which covers Tetanus, Diphtheria and Pertussis, people should get one every 10 years, specially if handling little children. I'm a Pharmacist, and at least in Puerto Rico, if the pharmacist is certified to give immunizations, we are authorized by the State to give a flu shot or a Tdap shot without a prescription.
