Vaccination and Immunization

Latest News



The Centers for Disease Control and Prevention (CDC) announced that approximately 81% of the nation's toddlers are receiving all the vaccinations in the recommended series."These results are terrific news," said Dr. Julie Gerberding, director of the CDC. "They illustrate the tremendous progress we've made in preventing what were once common childhood diseases. Most importantly, these results show that parents have high levels of confidence in our vaccination recommendations. It's encouraging to see that parents recognize the importance of protecting their children against diseases that while relatively uncommon, can cause serious harm."

In the Photoclinic item titled "Vaccine-Induced Herpes Zoster," by Julie L. Cantatore-Francis, MD, and Yelva Lynfield, MD (Consultant For Pediatricians, June 2005, pages 290 and 291), the dosage of acyclovir was incorrectly printed as 80 mg/d divided into 4 doses. The correct dosage is 80 mg/kg/d divided into 4 doses. We apologize for the error.

With the significant decline in disease caused by Haemophilus influenzae type b and Streptococcus pneumoniae achieved through vaccination, Neisseria meningitidis has moved to the forefront. Its emergence as the most important cause of bacterial meningitis challenges the pediatrician to prevent and control this terrible disease. Meningococcal disease can be easily misdiagnosed. It may present with different clinical manifestations, and its signs and symptoms may mimic those of common viral illnesses, such as influenza. The onset and progression of meningococcal disease are rapid. Although the rate of disease is highest in infants, morbidity and mortality rates for this disease are highest in adolescents and young adults, despite the existence of effective therapies.1

It has been difficult to determine the impact of influenza infection on infants and young children, because annual outbreaks of respiratory syncytial virus infection often overlap influenza outbreaks. But careful epidemiologic tests, combined with accurate, simple-to-perform viral diagnostic studies, have now clearly demonstrated that young children--particularly those younger than 2 years--are hospitalized because of influenza at a rate that equals or exceeds the influenza hospitalization rate for the elderly.

Many families feel that pediatricians just don't listen when they try to voice concerns about vaccines. Our recommendation: Identify each family's specific issues, target your response accordingly, and use a nonconfrontational approach. Time-consuming lectures on big subjects like immunology generally aren't needed.
