   <narrative xml:lang="SV">I malariaendemiska omr&#xe5;den leder upprepade infektioner med malariaparasiter till att en naturlig immunitet som skyddar mot sv&#xe5;r sjukdom utvecklas. Vad vi inte k&#xe4;nner till &#xe4;r hur l&#xe4;nge och hur bra denna immunitet kvarst&#xe5;r n&#xe4;r exponeringen mot malaria minskar efter framg&#xe5;ngsrika kontroll&#xe5;tg&#xe4;rder. Om malaria &#xe5;terintroduceras, och det immunologiska minnet har f&#xf6;rsvunnit hos befolkningen, &#xf6;kar risken f&#xf6;r utbrott och allvarlig sjukdom markant.I s&#xf6;dra Stillahavsregionen &#xe4;r malaria endemiskt i Papa Nya Guinea, Solomon &#xf6;arna och Vanuatu. Sedan 2015 har malariaelimineringen avstannat i Vanuatu och viss &#xf6;kning av malaria har setts p&#xe5; Papa Nya Guinea och Salomon &#xf6;arna. I &#xf6;riket Vanuatu har olika kontroll&#xe5;tg&#xe4;rder framg&#xe5;ngsrikt h&#xe5;llit malaria borta fr&#xe5;n vissa &#xf6;ar under flera &#xe5;rs tid, men p&#xe5; andra &#xf6;ar finns fortfarande m&#xe5;nga platser med p&#xe5;g&#xe5;ende smittspridning. N&#xe4;r m&#xe4;nniskors r&#xf6;rlighet mellan &#xf6;arna &#xf6;kar, &#xf6;kar risken f&#xf6;r att &#xe5;terintroducera malaria p&#xe5; &#xf6;ar som idag anses malariafria. F&#xf6;r att unders&#xf6;ka risken f&#xf6;r att malaria ska komma tillbaka, &#xe4;mnar vi bygga upp ett samarbete med Divine Word University och Vanuatus h&#xe4;lsoministerium d&#xe4;r vi ska unders&#xf6;ka hur immunologiskt minne uppr&#xe4;tth&#xe5;lls och bevaras beroende p&#xe5; olika grader av malariaincidens. I detta samarbete kommer vi att etablera ett Center f&#xf6;r malariaeliminering, samordna forskningsaktiviteter vilket inkluderar ett engagemang i samh&#xe4;llena, provtagning och analyser. Genom att f&#xf6;rst&#xe5; om immunitet uppr&#xe4;tth&#xe5;lls eller inte genererar vi kunskap som &#xe4;r viktigt i planering av den beredskap som beh&#xf6;vs f&#xf6;r att hantera malaria vid en &#xe5;terintroduktion. Studierna &#xe4;r ocks&#xe5; av betydelse f&#xf6;r utvecklingen av b&#xe4;ttre vaccin mot malaria.</narrative>
   <narrative xml:lang="EN">Naturally acquired immunity to malaria is maintained through repeated infections. The longevity of anti-malarial immunity in populations experiencing malaria control and successful elimination is largely unexplored. In Vanuatu, scaled-up interventions have resulted in sustained elimination on some islands for varying periods and focal transmission of different intensities on other islands. This gradient in malaria risk and exposure provides a model to study the maintenance of immune memory in a natural setting. In collaboration with Divine Word University and the Ministry of Health in Vanuatu, we will establish the Center for Malaria Elimination to conduct research that helps to assess the risk of malaria resurgence on islands where populations may have waning immunity. Through this partnership we will conduct community outreach, develop field protocols for sample collection and transport, and perform initial sample analyses. We anticipate the collaboration to expand future research to address pressing issues such as low-density infections and Plasmodium vivax hypnozoite reservoir that are relevant to not only Vanuatu, but also neighboring Solomon Islands and Papua New Guinea.</narrative>
