Key points
- 1
The MenACWY vaccine protects against four strains of meningococcal bacteria (A, C, W, and Y), which can cause serious infections including meningitis and septicaemia. It's offered as part of the routine childhood and teenage immunisation schedule, since certain age groups, including teenagers, have a higher carriage rate of these bacteria.

01 · Know
What is Meningococcal ACWY (MenACWY) Vaccine?
The MenACWY vaccine protects against four strains of meningococcal bacteria (A, C, W, and Y), which can cause serious infections including meningitis and septicaemia. It's offered as part of the routine childhood and teenage immunisation schedule, since certain age groups, including teenagers, have a higher carriage rate of these bacteria.
The vaccine is safe and effective, with the routine schedule designed to provide protection during the ages when risk of these infections is relatively higher, including before starting college or new social environments where close contact with others increases exposure.
02 · Understand
Clinical context
Teenagers and new college students are a particular target group
The MenACWY vaccine is specifically offered around the teenage years and before starting college partly because these are periods of increased social mixing and closer contact with others, which raises the risk of meningococcal transmission.

How to Access the Vaccine
- 1The vaccine is offered as part of the routine immunisation schedule at the appropriate age
- 2Contact your GP or public health nurse if your child has missed a scheduled dose
- 3Students starting college for the first time are often specifically encouraged to check their vaccination status
- 4Ask your GP if you have questions about catch-up vaccination for any missed doses

Practical steps
Don't Delay Catch-Up Vaccination If a Dose Was Missed
If your child or teenager missed their scheduled MenACWY vaccine, arranging catch-up vaccination promptly, rather than waiting, helps ensure protection during a period of relatively higher risk.
- 1Ensure vaccination at the recommended age.This is offered as part of the routine immunisation schedule.
- 2Check vaccination status before starting college.This is a particularly relevant time to confirm protection, given closer social contact in new environments.
- 3Arrange catch-up vaccination if a dose was missed.Contact your GP or public health nurse to arrange this promptly.
- 4Know the signs of meningitis and septicaemia.Even with vaccination, being aware of the symptoms remains valuable, since the vaccine doesn't cover every possible cause.

The MenACWY vaccine offers important protection against several strains of meningococcal bacteria during a period of relatively higher risk.
Checking vaccination status before starting college is a particularly important time to confirm protection.
