To

join the global drive against po­lio, Bhutan has in­tro­duced an in­jectable in­ac­ti­vated po­lio vac­cine (IPV) in its im­mu­ni­sa­tion pro­gram along with its ex­ist­ing oral po­lio vac­cine (OPV). The in­tro­duc­tion of the IPV, also known as ‘Salk vac­cine’, will help in less­en­ing the risks re­lated to re­moval of the type 2 com­po­nents of OPV, such as the rein­tro­duc­tion of wild type 2 po­liovirus or the emer­gence of vac­cine-de­rived po­liovirus. Pro­tect­ing chil­dren against type 2 po­lio virus, the new in­jectable vac­cine would be an es­sen­tial part of the WHO "Po­lio Erad­i­ca­tion and End Game Strate­gic Plan," which aims to erad­i­cate the dis­ease caused by both wild po­lio virus and OPV. Ow­ing to the risks as­so­ci­ated with the use of OPV, a grad­ual with­drawal of oral vac­cine is also un­der con­sid­er­a­tion world­wide.
