Immunization, Vaccines and Biologicals

Immunization highlights: 2011

Introduction

In 2011, there was important progress in a number of areas. About 180 countries across five WHO regions celebrated Immunization Week and the first official WHO-supported World Hepatitis Day was held to increase awareness and understanding of viral hepatitis and the diseases that it causes. The demand for new and underused vaccines is rising and more countries are introducing vaccines against meningococcal A epidemics, pneumococcal disease and rotavirus.

A selection of the most notable immunization achievements and events of 2011 is featured here, together with data based on the latest WHO/UNICEF global estimates for 2010.
