What is the difference between the meningitis B vaccine (Bexsero) and the meningitis booster?

The required Meningococcal ACWY-135 vaccination is different than the recommended Meningococcal B vaccination. All students aged 21 years and younger need to have a Meningococcal ACWY-135 vaccine on or after their 16^th birthday. Meningococcal B vaccinations are highly recommended but are not required at this time.
