The CDC has confirmed two undergraduate students at Rutgers University - New Brunswick have tested positive for meningitis.

According to the school, in a statement, having two cases over a short time suggests there is an outbreak at the university.

The meningitis vaccination required for students does not protect against this particular strain.

The school suggests at-risk students get a second shot, which includes:

All current and incoming undergraduate students.

Graduate students who live in undergraduate dorms.

All members of Rutgers University with medical conditions.

Microbiologists routinely exposed to bacteria.
