Immunization, Vaccines and Biologicals

Immunization highlights 2015

There is arguably no single preventive health intervention more cost-effective than immunization in saving lives and protecting people’s health.

A selection of the most notable immunization achievements and events in 2015 as a result of WHO’s involvement is featured here.

Vaccines: A global health success story

It’s no secret that vaccines are considered 1 of the greatest global health achievements. Every year they avert an estimated 2 to 3 million deaths.

During the last 2 centuries, vaccines have eradicated smallpox, reduced global child mortality rates and prevented countless birth defects and lifelong disabilities. But, the success story of vaccination is not yet finished.

Global switch in oral polio vaccines

Between 17 April and 1 May 2016, 155 countries and territories will stop using the trivalent oral polio vaccine (tOPV), which targets all three strains of wild poliovirus, and replace it with bivalent OPV (bOPV), which targets the remaining two wild polio strains, types 1 and 3.

Immunization game-changers should be the norm worldwide

During World Immunization Week, WHO highlights recent gains in vaccines and immunization and outlines further steps needed to close the immunization gap. “Last year immunization led to some notable wins in the fight against polio, rubella and maternal and neonatal tetanus,” says Dr Margaret Chan, WHO Director-General.
“But they were isolated wins. Polio was eliminated in 1 country, tetanus in 3, and rubella in 1 geographical region. The challenge now is to make gains like this the norm.”
