Four in five children (83 percent) worldwide received the recommended three doses of diphtheriatetanuspertussis (DTP) vaccine during infancy in 2011, according to new data released in the Morbidity and Mortality Weekly Report and in the WHO Weekly Epidemiological Record (WER).
The new data show sustained progress from the previous two years, and a significant achievement from when WHOs Expanded Programme on Immunization (EPI) was established nearly 40 years ago. At that time, fewer than 5 percentÂ of the worlds children were being vaccinated against these three deadly diseases.
Achieving DTP vaccination of infants before they reach 12 months is one of the most important indicators of how effective vaccination programmes are in reaching children with life-saving vaccines.
While substantial progress has been made, the new data show more than 22 million children, mostly living in less-developed countries, missed out on the three basic vaccinations during their first year of life in 2011.
About half of all incompletely vaccinated children live in three countries: India, Indonesia and Nigeria. These countries have large child populations and their immunization programs are hampered by occasional problems with vaccine supply and inaccessibility of vulnerable populations.
At this years World Health Assembly, Ministers of Health endorsed a landmark Global Vaccine Action Plan - a roadmap to prevent millions of deaths by 2020 through more equitable access to existing vaccines for people in all communities. The Plan involves four goals:
- strengthening routine immunization to meet vaccination coverage targets
- accelerating control of vaccine-preventable diseases
- introducing new and improved vaccines
- spurring research and development for the next generation of vaccines and technologies
An accessible and well-functioning immunization programme should be a key component of public health services in every country, says Dr. Jean-Marie Okwo-Bele, director of WHOs Department of Immunization, Vaccines and Biologicals. By supporting countries to strengthen their health systems through the implementation of the new Global Vaccine Action Plan, we can increase global access to vaccines and make an impact on the lives of millions of people.
An estimated 130 million infants are born each year. Vaccinating these children to protect them from diphtheria, tetanus, whooping cough (pertussis) as well as measles, polio, and other preventable diseases is vital to keeping them alive and healthy. WHO estimates that immunizations save betweenÂ 2 millionÂ andÂ 3 million lives per year.
Strengthening routine immunization services is crucial to achieve the Millennium Development Goal 4 of reducing deaths among children underÂ 5 by two-thirds by 2015 compared to 1990.
