Expanded programme on immunization

Immunization safety

The landscape of vaccine use is rapidly changing in the region. In the Western Pacific Region, vaccines are being offered routinely and during large-scale campaigns within the context of disease control goals and targets set by Member States. In addition, several new vaccines have been recently introduced or are planned for introduction. Although modern vaccines are safe, the increased number of doses and opportunities for vaccination may lead to vaccine safety concerns. The quality of immunization safety surveillance widely varies across the Region.

Vaccine regulation

Vaccination is documented as the most effective primary intervention to reduce the burden of disease and enhance health. Assured quality vaccines are essential to effective immunization programmes. Given the current emphasis including introduction of new vaccines, independent, competent, and effective regulatory systems are necessary to oversee the supply of assured quality vaccines.
