Invasive Pneumococcal Disease in Young Children Before Licensure of 13-Valent Pneumococcal Conjugate Vaccine — United States, 2007
In February 2010, the Advisory Committee on Immunization Practices (ACIP) issued recommendations for use of a newly licensed 13-valent pneumococcal conjugate vaccine (PCV13). To characterize the potential effect of the new vaccine on invasive pneumococcal disease among children aged <5 years in the United States, CDC and investigators analyzed data from Active Bacterial Core surveillance. This report summarizes the results of that analysis.

Japanese Encephalitis Vaccines — Recommendations of the Advisory Committee on Immunization Practices (ACIP)
Japanese encephalitis virus (JEV), a mosquito-borne flavivirus, is the most common vaccine-preventable cause of encephalitis in Asia. Japanese encephalitis (JE) occurs throughout most of Asia and parts of the western Pacific. This report updates the 1993 recommendations by CDC’s Advisory Committee on Immunization Practices (ACIP) regarding the prevention of JE among travelers. This report summarizes the epidemiology of JE, describes the two JE vaccines that are licensed in the United States, and provides recommendations for their use among travelers and laboratory workers.
