U.S. regulators have approved a new pneumonia vaccine from Merck, more than a month after OK’ing an improved version of rival Pfizer’s shot.

Both new shots offer better protection against bacteria that can cause pneumonia, meningitis and blood infections, as well as garden-variety ear and sinus infections.

Merck said the Food and Drug Administration approved its shot, called Vaxneuvance, for people ages 18 and up. It protects against 15 of the roughly 100 pneumococcal strains, including those most responsible for severe disease.

Merck hasn’t disclosed its shot’s price or when it will be launched.
