Vaccination is the administration of antigens to stimulate an individual's immune system to develop adaptive immunity to a pathogen. Vaccines can prevent or reduce the severity of infections. On the occasion of the World Immunization Week, which starts Friday, the World Health Organization reported that one-fifth of the world's children are still not receiving routine life-saving vaccinations and efforts to ensure global immunization coverage remain far off track. WHO said, "Global immunization coverage varies greatly between different kinds of vaccines, with 84% global coverage for DTP3, polio and measles, but only 14% for rotaviruses, the most common cause of severe diarrhea. Millions of children remain at risk of illness, disability or death because they are not getting the immunization they need."
WHO said, "Nearly 22 million infants, many living in the world's poorest countries, have been missed out in 2013 on the routine vaccine against diphtheria, whooping cough and tetanus (DTP3). And nearly half of them are in three countries- India, Pakistan and Nigeria."
Vaccination for Children
Vaccines are biological products that impart immunity to the recipient. Vaccines may be live attenuated, killed or toxoids.
Jean-Marie Okwo-Bele, head of WHO's vaccine unit, said, "This is of grave concern. There are still 1.5 million premature deaths due to vaccine preventable diseases each year. Today WHO is calling for the global community to close the immunization gap and the unnecessary disability and deaths caused by the failure to vaccinate. The world has made great strides in recent decades in raising immunization rates, from as low as 5% in some countries in the mid-1970s to a global average of 84% in 2013. And 129 countries boast immunization levels above 90%, with vaccines estimated to save as many as three million lives each year. But the progress had been plateauing in recent years, despite a commitment in 2012 by all WHO members to a plan to ensure all children are immunized. There are a number of reasons for the lack of progress, including the cost of vaccines, weak health systems and lack of access in poorer countries. Armed conflicts and insecurity also limit access, as do emergencies like the west African Ebola outbreak, with recent, unverified numbers indicating that immunization levels in Guinea, Liberia and Sierra Leone dropped as much as 30 percent at the height of that crisis."
Philippe Duclos, WHO senior health advisor, "A number of parents also refuse to vaccinate their children against measles, mumps and rubella, claiming it is responsible for increasing cases of autism, a theory repeatedly disproven by a range of studies."
