PASADENA, Calif. — A new vaccine against pneumococcal disease appears as safe as an older one, according to a new study.
The study, conducted by Kaiser Permanente and published Wednesday in the journal Vaccine, compared the new 13-valent vaccine with the seven-valent one used before 2010. The Food and Drug Administration approved the newer vaccine, called PCV13, in 2010 after a series of trials. The valent number refers to the number of varieties of pneumococcal disease the vaccine prevents.
