Pfizer Responds to the Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention’s Vote to Revise the Recommendation for Routine Use of Prevnar 13® for the Prevention of Pneumococcal Disease for Adults 65 Years or Older

June 26, 2019

NEW YORK, N.Y., June 26 - Pfizer Inc. (NYSE: PFE) today responds to the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention’s (CDC) vote to revise the pneumococcal vaccination guidelines and recommend Prevnar 13® (Pneumococcal 13-valent Conjugate Vaccine [Diphtheria CRM197 Protein]) for adults aged 65 and older based on the shared clinical decision making of the provider and patient. This vote means the decision to vaccinate should be made at the individual level between health care providers and their patients.

“This revised recommendation reinforces that Prevnar 13® is considered safe and effective by the FDA and ACIP and helps address remaining persistent vaccine type pneumococcal disease in the population of adults age 65 years or older, which causes thousands of pneumococcal pneumonia cases every year in the United States,” said Luis Jodar, Pfizer Vaccines, Chief Medical and Scientific Affairs Officer. “Direct vaccination remains the best available tool to help prevent against pneumococcal disease and the revised recommendation emphasizes the importance of the health care professional and patient relationship in shared decision making regarding vaccination.”

ACIP is a group of medical and public health experts that makes vaccine recommendations to help control disease in the United States. In 2014, the ACIP voted to recommend Prevnar 13® for adults 65 years or older. In 2012, Prevnar 13® was recommended by ACIP for adults 19 years of age and older with immunocompromising conditions (e.g., HIV, chronic renal failure, cancer), functional or anatomic asplenia (e.g., sickle cell disease), cerebral spinal fluid leak, and Cochlear implants.

“Pfizer remains committed to helping protect against the potentially devastating effects of pneumococcal disease and continuing to develop our pneumococcal vaccine pipeline,” added Jodar.


  • Severe allergic reaction (e.g., anaphylaxis) to any component of Prevnar 13®or any diphtheria toxoid-containing vaccine is a contraindication
  • Immunocompromised individuals or individuals with impaired immune responsiveness due to the use of immunosuppressive therapy may have reduced antibody response
  • In adults, the most common side effects were pain, redness, and swelling at the injection site, limitation of arm movement, fatigue, headache, muscle pain, joint pain, decreased appetite, vomiting, fever, chills, and rash
  • Apnea following intramuscular vaccination has been observed in some infants born prematurely. Vaccination of premature infants should be based on the infant's medical status, and the potential benefits and risks
  • In infants and toddlers, the most commonly reported serious adverse events were bronchiolitis (0.9%), gastroenteritis (0.9%), and pneumonia (0.9%)
  • In children 6 weeks through 17 years, the most commonly reported solicited adverse reactions were injection site tenderness, redness, or swelling, irritability, decreased appetite, decreased or increased sleep, and fever

Prevnar 13® is a vaccine indicated in children 6 weeks through 17 years (prior to the 18th birthday) for active immunization for the prevention of invasive disease caused by Streptococcus pneumoniae serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F, and for children 6 weeks through 5 years of age (prior to the 6th birthday) for the prevention of otitis media caused by 7 of the 13 serotypes only (4, 6B, 9V, 14, 18C, 19F, and 23F).

In adults 18 years of age and older, Prevnar 13® is indicated for active immunization for the prevention of pneumonia and invasive disease caused by S. pneumoniae serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F. 

Limitations of Use and Effectiveness
