[One] affect of the widespread use of Prevnar has been the emergence of antibiotic resistant bacterial strains. In the 1970s, virtually all strains were exquisitely sensitive to penicillin; since the introduction of Prevnar, many strains have become highly resistant. In a study published in 2003, more than one third of pnumococcal isolates tested were ... resistant to other common antibiotics, including ceftriaxone (Rocephin) (fourteen percent), erythromycin (twenty-two percent), and trimethoprim/sulfa (ie Bactrim) (thirty-one percent). A full twenty percent of S pneumoniae isolates in the study were resistant to all four antibiotics.(3)

There may be other drugs that can affect Prevnar. Tell your doctor about all the prescription and over-the-counter medications your child has received. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your child's doctor.

The medical community as well as the regulatory bodies were eagerly awaiting the arrival of Prevnar. It was the first vaccine to be designated by the FDA for ‘priority review’, meaning that it clearly met an urgent need, and was approved by the FDA less than one year later.
