Global Advisory Committee on Vaccine Safety review of pentavalent vaccine safety concerns in four Asian countries
ثبت نشده
چکیده
Since 2008, Haemophilus influenza type b (Hib) vaccine has increasingly been introduced into Asian countries immunisation programmes. Hib vaccine has mainly been introduced as a combination pentavalent vaccine, which has replaced the traditional DTwP or DTPwP-HepB vaccines. As expected with the introduction of a new vaccine, there has been increased attention to serious adverse events following immunization (AEFI) and this presented challenges in several countries from the WHO Southeast Asian (SEAR) and Western Pacific (WPR) regions. At the 12-13 June 2013 meeting of the Global Advisory Committee on Vaccine Safety (GACVS), four countries that introduced pentavalent vaccines from 3 different manufacturers presented their experience.

Vaccines have contributed enormously in reducing the impact of many infectious diseases, and the expanded use of new and existing vaccines provides unprecedented potential for further reducing the global burden of infectious diseases. Yet, as with the deployment of other technologies, their use may also sometimes be associated with undesirable effects that need to be identified rapidly, underst...

The World Health Organisation (WHO) has recently revised how adverse events after immunization (AEFI) are classified. Only reactions that have previously been acknowledged in epidemiological studies to be caused by the vaccine, are classified as a vaccine-product–related-reaction. Deaths observed during post-marketing surveillance are not considered as “consistent with causal association with v...

BACKGROUND Prefilled syringes are the standard in developed countries but logistic and financial barriers prevent their widespread use in developing countries. The current study evaluated use of a compact, prefilled, autodisable device (CPAD) to deliver pentavalent vaccine by field actors in Senegal and Vietnam. METHODS We conducted a logistic, programmatic, and anthropological study that inc...

Background In 2013, the World Health Organization's (WHO's) Strategic Advisory Group of Experts (SAGE) recommended that all 126 countries using only oral polio vaccine (OPV) introduce at least 1 dose of inactivated polio vaccine (IPV) into their routine immunization schedules by the end of 2015. In many countries, the addition of IPV would necessitate delivery of multiple injectable vaccines (h...
