About Prevnar 13
Prevnar 13, which is based on the scientific foundation of Prevnar® (Pneumococcal 7-valent Conjugate Vaccine [Diphtheria CRM197 Protein]), was first introduced in December 2009 in Europe and is now approved for use in infants and young children in more than 100 countries worldwide. Prevnar 13, like Prevnar, uses company-pioneered conjugation technology that has been shown to confer a high antibody response in infants and toddlers. This has not yet been established in adults.
Pneumococcal Disease
Pneumococcal disease (PD) is a group of illnesses caused by the bacterium Streptococcus pneumoniae (S. pneumoniae), also known as pneumococcus. The most common manifestations of PD in adults 50 years and older include invasive infections, such as bacteremia and meningitis, as well as non-invasive infections, such as non-invasive/non-bacteremic pneumonia. As adults age, they become more susceptible to infectious diseases due to their aging immune systems. PD is associated with significant morbidity and mortality and claims the lives of an estimated 1.6 million people per year, mostly in infants and older adults.

Indication for Prevnar 13
In the United States, Prevnar 13 is a vaccine approved for use in children 6 weeks through 5 years of age (prior to the 6th birthday). Prevnar 13 is indicated for active immunization for the prevention of invasive disease caused by 13 strains of Streptococcus pneumoniae (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F). Prevnar 13 is also indicated for the prevention of otitis media (ear infection) caused by 7 strains of Streptococcus pneumoniae (4, 6B, 9V, 14, 18C, 19F, and 23F). No efficacy data for ear infections are available for strains 1, 3, 5, 6A, 7F, and 19A.
Important Safety Information for Prevnar 13
- Prevnar 13 should not be given to anyone with a severe allergic reaction to any component of Prevnar 13, Prevnar, or any diphtheria toxoid–containing vaccine.
- Prevnar 13 may not protect all individuals receiving the vaccine.
- Protection against ear infections is expected to be less than that for invasive disease.
- Children with weakened immune systems may have a reduced immune response to Prevnar 13.
- A temporary pause of breathing following vaccination has been observed in some infants born prematurely.
- The most commonly reported serious adverse events include bronchiolitis (an infection of the lungs) (0.9%, 1.1%), gastroenteritis (inflammation of the stomach and small intestine) (0.9%, 0.9%), and pneumonia (0.9%, 0.5%) for Prevnar 13 and Prevnar, respectively.
- The most common side effects are redness, swelling and tenderness at the injection site, fever, decreased appetite, irritability, increased sleep, and decreased sleep. Any side effects associated with the vaccination should be reported to your child's health care provider.
- Ask your child's health care provider about the risks and benefits of Prevnar 13. Only a health care provider can decide if Prevnar 13 is right for your child.
