  • Meningococcal ACWY
  • Booster Doses

What do you do if an adult patient is in a high-risk situation for meningococcal disease (for example travel to sub-Saharan Africa) and doesn’t know whether they received MenACWY or quadrivalent meningococcal polysaccharide vaccine (MPSV4) in the past? Should we vaccinate them?

If the person cannot provide written documentation of the previous vaccination you should assume they are unvaccinated and vaccinate accordingly.
