WHO reports on global diphtheria-tetanus-pertussis vaccination efforts

"Four in five children (83 percent) worldwide received the recommended three doses of diphtheria-tetanus-pertussis (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)," a WHO media note reports. According to the media note, "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" (11/1).
