Spain's Ministry of Health, Social Services and Equality provides vaccination coverage estimates based on data supplied to the ministry by the country's autonomous communities (administrative 1 divisions). The estimates, presented on the ministry's website and updated at certain intervals, are based on doses of vaccines administered through official vaccination services, and they cover primary and booster vaccinations for polio, DTPa, Hib, and meningoccocal disease C, as well as MMR, hepatitis B, HPV, and influenza vaccinations. National estimates are expressed only in percentages; estimates at the autonomous community level include numbers of doses administered.
