According to the World Health Organization (WHO), pneumococcal disease is the number one vaccine-preventable cause of death in children younger than five years of age. Due to the significant burden of pneumococcal disease and demonstrated vaccine efficacy, WHO recommends the priority inclusion of PCV7 in national childhood immunization programs worldwide. WHO notes that if other pneumococcal vaccines that offer expanded protection become available, countries should assess whether it would be helpful to switch to these vaccines.
Indication
Prevnar is indicated for active immunization of infants and toddlers against invasive disease caused by Streptococcus pneumoniae, including bacteremia (bloodstream infection) and meningitis (infection of the membranes surrounding the brain and spinal cord) caused by the seven serotypes in the vaccine. The seven serotypes (strains) of S. pneumoniae included in the vaccine (4, 6B, 9V, 14, 18C, 19F, and 23F) are the strains that most commonly cause these serious diseases in children. The routine schedule is 2, 4, 6, and 12 to 15 months of age.
Prevnar is also indicated for immunization of infants and toddlers against otitis media (ear infections) caused by the seven serotypes included in the vaccine. Protection against ear infections is expected to be less than that for invasive disease.
As with any vaccine, Prevnar may not protect all individuals receiving the vaccine from serious invasive disease cause by S. pneumoniae. This vaccine should not be used for treatment of active infection.
Important Safety Information for Prevnar
In clinical trials, the most frequently reported adverse events included injection site reactions, fever (greater than or equal to 38 degrees C/100.4 degrees F), irritability, drowsiness, restless sleep, decreased appetite, vomiting, diarrhea, and rash.
Risks are associated with all vaccines, including Prevnar. Hypersensitivity to any vaccine component, including diphtheria toxoid, is a contraindication to its use. Prevnar does not protect 100% of children vaccinated. Immunization with Prevnar does not substitute routine diphtheria immunization.

In particular, clinical trial data are subject to differing interpretations, and the views of regulatory agencies, medical and scientific experts and others may differ from ours. As noted above, the clinical trial data presented at the meeting reflect only four of 13 core Phase 3 studies of PCV13 in the pediatric population and, accordingly, do not represent the totality of data and other information that may affect regulatory review and commercialization of PCV13. There can be no assurance that PCV13 will ever receive regulatory approval or be successfully developed and commercialized. Other risks and uncertainties that could cause actual results to differ materially from those expressed or implied by forward-looking statements include, without limitation, the inherent uncertainty of the timing and success of, and expense associated with, research, development, regulatory approval and commercialization of our products and pipeline products; government cost-containment initiatives; restrictions on third-party payments for our products; substantial competition in our industry, including from branded and generic products; emerging data on our products and pipeline products; the importance of strong performance from our principal products and our anticipated new product introductions; the highly regulated nature of our business; product liability, intellectual property and other litigation risks and environmental liabilities; uncertainty regarding our intellectual property rights and those of others; difficulties associated with, and regulatory compliance with respect to, manufacturing of our products; risks associated with our strategic relationships; economic conditions including interest and currency exchange rate fluctuations; changes in generally accepted accounting principles; trade buying patterns; the impact of legislation and regulatory compliance; risks and uncertainties associated with global operations and sales; and other risks and uncertainties, including those detailed from time to time in our periodic reports filed with the Securities and Exchange Commission, including our current reports on Form 8-K, quarterly reports on Form 10-Q and annual report on Form 10-K, particularly the discussion under the caption "Item 1A, RISK FACTORS" in our Annual Report on Form 10-K for the year ended December 31, 2007, which was filed with the Securities and Exchange Commission on February 29, 2008.
