Advisory Committee on Immunization Practices Recommends Pfizer’s PREVNAR 20® for Adults Previously Vaccinated with PREVNAR 13®

NEW YORK, October 20, 2022 - Pfizer Inc. (NYSE:PFE) today announced that that the Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) voted to recommend a single dose of PREVNAR 20® (Pneumococcal 20-valent Conjugate Vaccine) to help protect adults previously vaccinated with PREVNAR 13® (Pneumococcal 13-valent Conjugate Vaccine [Diphtheria CRM197 Protein]) or both PREVNAR 13® and PPSV23 against invasive disease and pneumonia caused by the 20 Streptococcus pneumoniae (pneumococcus) serotypes in PREVNAR 20®. 

Specifically, the ACIP voted to recommend the following: 

•    Adults who have received PCV13 only are recommended to receive a dose of PCV20 at least 1 year after the PCV13 dose or PPSV23 as previously recommended to complete their pneumococcal vaccine series.
•    Adults with an immunocompromising condition, cochlear implant, or cerebrospinal fluid leak who have received both PCV13 and PPSV23 with incomplete vaccination status are recommended to complete their pneumococcal vaccine series by receiving either a dose of PCV20 at least 5 years after the last pneumococcal vaccine dose or PPSV23 as previously recommended.
•    Shared clinical decision-making is recommended regarding administration of PCV20 for adults aged > 65 years who completed their vaccine series with both PCV13 and PPSV23. If a decision to administer PCV20 is made, a dose of PCV20 is recommended at least 5 years after the last pneumococcal vaccine dose.

“Today’s vote underscores the importance of PREVNAR 20® and it’s seven additional serotypes helping prevent invasive pneumococcal disease and pneumonia among adults,” said Luis Jodar, Infectious Disease and Evidence Generation, Chief Medical Affairs Officer, Pfizer. “We commend the ACIP and CDC for recognizing the public health benefit and further clarifying the adult pneumococcal pneumonia recommendations. We are confident this will help improve vaccination rates and ultimately reduce disease burden in this population.”

Details of ACIP’s recommendations will be available from the CDC. Provisional recommendations will be forwarded to the director of the CDC and the U.S. Department of Health and Human Services for review and approval, with final recommendations published in the CDC’s Morbidity and Mortality Weekly Report (MMWR).

“With more than 26 million adults over the age of 19 who have been previously vaccinated with PREVNAR 13®, today’s ACIP vote recognizes the importance of helping to protect them against the seven additional serotypes contained in PREVNAR 20®,” said Angela Hwang, President, Global Biopharma Business, Pfizer. “With these recommendations, coupled with the previous recommendation for pneumococcal conjugate vaccine naive adults, providers now may help protect all of their eligible adult patients with a single dose of PREVNAR 20® – regardless of pneumococcal vaccination history.”

In October 2021, ACIP recommended for routine use one dose of Pfizer’s PREVNAR 20® in adults 65 years of age or older who have not previously received a pneumococcal conjugate vaccine or whose previous vaccination history is unknown, and adults aged 19 years of age or older with certain underlying medical conditions, such as asthma or diabetes, or other risk factors who have not previously received a pneumococcal conjugate vaccine or whose previous vaccination history is unknown.

About PREVNAR 20®
PREVNAR 20® is Pfizer’s next-generation pneumococcal conjugate vaccine that includes capsular polysaccharide conjugates for the 13 serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F) already included in Prevnar 13® (Pneumococcal 13-valent Conjugate Vaccine [Diphtheria CRM197 Protein]). The vaccine also contains capsular polysaccharide conjugates for seven additional serotypes (8, 10A, 11A, 12F, 15B, 22F and 33F) that cause invasive pneumococcal disease (IPD),4,5,6,7,8 and have been associated with high case-fatality rates,9,10,11,12 antibiotic resistance,13,14,15 and/or meningitis.16,17 PREVNAR 20™ contains the broadest serotype coverage of any available conjugate vaccine and helps protect against the 20 Streptococcus pneumoniae serotypes in the vaccine.

On June 8, 2021, Pfizer announced the U.S. Food and Drug Administration (FDA) approved PREVNAR 20® for the prevention of invasive disease and pneumonia in adults age 18 years or older. On September 30, 2022, the FDA approved the addition of information in the PREVNAR 20® prescribing information regarding coadministration with an influenza vaccine, adjuvanted (Fluad Quadrivalent) in adults aged 65 years or older.

On February 15, 2022, Pfizer announced the European Medicines Agency (EMA) approved the company’s 20-valent pneumococcal conjugate vaccine, which is marketed in the European Union (EU) under the brand name APEXXNAR.
