Why should my student get this vaccine?

  1. Effective: The vaccine works very well when given just before or early in the teenage years.
  2. Age appropriate: The teenage years are times when young people are more likely to try activities that increase the risk of infection. This is why it is important that youth get the vaccine before this stage.
  3. Schools: The law says that students in grades 7-12 are required to have this vaccine to go to school. Many colleges and universities need proof of having this vaccine as well.
  4. Travel: This vaccine is recommended for travel to some countries.

Note: This vaccine is different from the meningococcal-C vaccine given at one year of age.
