A record 123 million infants were immunized globally in 2017 with at least one dose of the diphtheria-tetanus-pertussis vaccine , according to data released today by the World Health Organization and UNICEF.
The data shows that:
Despite these successes, almost 20 million infants did not receive the benefits of full immunization in 2017, as they were not vaccinated with three doses of the diphtheria-tetanus-pertussis vaccine. Of these, almost 8 million (40 per cent) live in fragile or humanitarian settings, including countries affected by conflict. In addition, a growing share are from middle-income countries, where inequity and marginalization, particularly among the urban poor, prevent many from getting immunized.
As populations grow, more countries need to increase their investments in immunization programmes. To reach all children with much-needed vaccines, the world will need to vaccinate an estimated 20 million additional children every year with three doses of the diphtheria-tetanus-pertussis vaccine (DTP3); 45 million with a second dose of measles vaccine; and 76 million children with 3 doses of pneumococcal conjugate vaccine.
