The use of modern-day vacines has resulted in the marked reduction and, in some cases, elimination of a number of infectious diseases. The success of these vaccination programs has identified immunization as the number one public health achievement of the 20th century and among the most effective interventions in medicine. This article will consider the recent changes in the recommendations for use of influenza and hepatitis A vaccines during childhood and review clinical-trial results for the new infant vaccine licensed in 2006 for the prevention of rotavirus infection.
