March 17 (UPI) -- Two people have died out of 15 cases of bacterial meningitis at the University of Kent in England, and students are being offered a vaccine for prevention.

The vaccine has been given to children in the United Kingdom since 2015, but most people over age 10 haven't had it as part of their childhood vaccine schedule.

The two who died from the outbreak had bacterial strain B of meningococcal disease, the U.K. Health Security Agency said. The other 11 cases are under investigation.

One of those who died from the disease is a year 13 student (around age 17 or 18) from Faversham, England, named Juliette. Her last name is withheld for her privacy, The Guardian reported. Another who died is an unnamed student at University of Kent.
