The Food and Drug Administration (FDA) approved a vaccine that provides expanded protection against meningitis. Meningitis is a dangerous infection caused by meningococcal bacteria. Although the United States records just a few hundred cases per year, the infection is extremely deadly. About 1 in 5 of meningitis survivors experience a long-term disability. The new vaccine, developed by Pfizer, targets five types of meningococcal bacteria. Currently people must receive two separate vaccine to receive protection against all five types. The new vaccine, called Penbraya, offers the same protection in two doses, rather than four. The FDA approved Penbraya for individuals ages 10-25 years old.
