In general, in 2011, countries in the Asian and Pacific region had a DPT3 coverage of 80 per cent or above, with the exception of the Lao People’s Democratic Republic (78 per cent), Timor-Leste (67 per cent) and Papua New Guinea (61 per cent). In some countries, DPT3 coverage was lower in 2011 than it was in 1990; examples include India (100 per cent to 85 per cent), Indonesia (88 per cent to 83 per cent) and the Philippines (88 per cent to 80 per cent). Immunization for this disease is also used as a proxy indicator of a fully immunized child because it is usually given at the age of 9 months, by which time all other antigens have been provided.
