2022-2026

DrSunilBahlpresentedanupdateonthestatusofimmunizationandVPDelimination/controlintheSouth-EastAsiaRegionandtheSouth-EastAsiaRegionalVaccineImplementationPlan2022–2026.

Thekeypointsfromthepresentationwere:

Routineimmunizationcoverage(3dosesofdiphtheria-tetanus-pertussisvaccine/DTP3)intheSouth-EastAsiaRegionincreasedsteadilytoreach91%in2019,butdroppedfrom91%to85%in2020.

Thenumberofunvaccinatedorunder-vaccinatedchildrenincreasedfrom

3millionto4.9million.

Sixcountriesmaintainedimmunizationcoverage(DTP3)above90%in2020,althoughsubnationalvariabilitywasseenin2019and2020.

Despitedelays,newvaccineintroductionandsurveillancewereprogressingwellintheRegionwithanumberofcountriesintroducingnewvaccinesduring2020–2021.

However,surveillanceactivitiesencounteredmultiplechallengesduetotheCOVID-19pandemic.

ThemainachievementsoftheRegionincludemaintainingthepolio-freestatus(certifiedin2014),maintainingthematernalandneonataltetanuseliminationstatusoftheRegion(achievedin2016),makingprogresstowardstheReginalFlagshipProgrammeon–“measlesandrubellaeliminationby2023”,eliminationofmeaslesinfivecountries(achievedbetween2017and2019)andeliminationofrubellaintwocountries(achievedin2020).HepatitisBwascontrolledthroughimmunizationinfourcountries(achievedin2019).Theseachievementsareatariskbecauseofthereductionintheroutineimmunizationcoverage.
