it does not include cases of vaccine-associated paralytic polio (VAPP) and cases of non polio acute flaccid paralysis [AFP]).
** Neonatal Tetanus and Total Tetanus cases equality may be the result from a lack of non-Neonatal Tetanus surveillance system.
*** For 2019, if a country did not submit a joint reporting form, measles and rubella cases were sourced from data reported through the monthly surveillance data available from:
