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.
