Zika virus outbreaks prompt warnings to pregnant women

The rapid spread of Zika virus in the Americas, where there is little population immunity, is a major concern, especially given the possible link between infection during pregnancy and the congenital abnormality microcephaly, the World Health Organization has warned.

Is the timing of recommended childhood vaccines evidence based?

Vaccines undergo extensive testing and review before licensing to evaluate their immunogenicity, safety, and effectiveness in preventing disease.1 For example, prelicensing trials of pneumococcal conjugate and rotavirus vaccines are among the largest randomised controlled trials ever conducted, enrolling tens of thousands of infants.2 3 4 In addition to randomised controlled trials, which produce the highest level of evidence and provide the basis for vaccine licensure, vaccine policy also benefits from the additional supportive evidence obtained from thousands of other types of vaccine studies. Such studies generate critical data regarding age specific immunogenicity, dose and dosing intervals, interaction with other vaccines, duration of immunity, and overall vaccine safety to inform schedules.

Acquired Immunity

Acquired (adaptive or specific) immunity is not present at birth. It is learned. As a person’s immune system encounters foreign substances (antigens), the components of acquired immunity learn the best way to attack each antigen and begin to develop a memory for that antigen. Acquired immunity is also called specific immunity because it tailors its attack to a specific antigen previously encountered. Its hallmarks are its ability to learn, adapt, and remember.
