The human papillomavirus (HPV) is responsible for most cervical and anogenital cancers. The HPV vaccine can effectively reduce invasive cervical cancer

however, HPV vaccine uptake is low in certain groups due to hesitancy and refusal, which undermines the success of the vaccine. In Sweden, HPV vaccine hesitancy has mainly been observed among parents and adolescents in socioeconomically disadvantaged communities with large immigrant populations.The purpose of this project is therefore to co-design and assess the feasibility and preliminary effects of digital health intervention tools to reduce HPV vaccine hesitancy and increase uptake of this vaccine in socioeconomically disadvantaged communities in Stockholm, Sweden. Several research questions shall assess whether a co-designed digital health intervention has the potential to improve HPV uptake, awareness and confidence.The project involves three sub-studies implemented by an interdisciplinary team.  Study 1 will involve a formative stage whereby adolescents, parents/guardians and school nurses situated in socially disadvantaged areas in Stockholm will be interviewed to understand their perspectives and concerns related to the HPV vaccine. Thereafter, study 2 will use knowledge gained from study 1 to inform the co-design phase where adolescent boys/girls and their parents/guardians are invited to develop and provide feedback on content and prototypes for digital health interventions. Finally, study 3 will involve pilot-testing of the intervention for feasibility, acceptability and preliminary effect, using a cluster-randomized design.This project is highly feasible as it builds on the study team’s previous research, which show that immigrant communities in Sweden experience poorer health outcomes as well as vaccine hesitancy. Because 1 in 5 Swedes have a migrant background this study is relevant to Swedish society. An appropriate and accessible digital health intervention has the potential to prevent cervical cancer, saving lives and reducing future burdens on an overstretched Swedish healthcare system. The results from this project will be generalizable to similar contexts in Sweden and possibily beyond.

Reports warn of serious pandemic harm on adolescent girls´ and young womens´ (AGYW, 13-24 yrs) lives including on their reproductive health in Africa. The specific aims of this project are to: 1) evaluate the impact of COVID-19 societal restrictions including school closures on unintended pregnancy and contraceptive use among AGYW, and estimate the long-term societal cost of these restrictions in Uganda (Study 1)

2) explore AGYWs’ and other key stakeholders’ understanding of risk factors and underlying reasons for unintended pregnancies and low contraceptive use in the wake of the pandemic and beyond (Study 2)

3) co-design a resilient intervention package aiming to reduce unintended pregnancies and improve contraceptive use among AGYW (Study 3)

and 4) implement and test the intervention package using a cluster-randomized design. Data will be drawn from a large population cohort (rural/urban, &lt

20,000 people) including intervention outcomes as well as additional quantitative and qualitative data collection. The project is expected to take 3 years and is a collaboration involving a very experienced and skilled team of Swedish and Ugandan researchers who earlier received a joint VR Links grant. The project is anticipated to yield high quality unique evidence about the impact of pandemic restrictions, including extensive school closures on AGYWs. The expected results will contribute to better resilience and pandemic preparedness in resource-poor health systems across Africa.

In sub-Saharan Africa, adolescent girls and young women (AGYW) aged 15-24 years are more likely than older women to acquire HIV, and once pregnant, to transmit HIV to their infants and drop out of care. This highlights an urgent need to revisit the current one-size-fits-all model of prevention of mother-to-child transmission (PMTCT) programs. The purpose of this project is to optimize PMTCT care for AGYWs, and later their infants, in Tanzania – a setting where HIV remains endemic. To do so, we will use data from a large registry-based cohort (N≈13,800 with 22% 15-24 years) to investigate PMTCT service uptake, retention and health outcomes for AGYWs, as well as subsequent pregnancies and contraceptive use (study 1). We will combine this with a nested prospective cohort to identify social-structural predictors of these outcomes (study 2). We will utilize findings to develop (together with young women, health providers and managers) and prototype a package of micro-interventions that can be implemented in routine care to optimize PMTCT services for AGYWs. Using a cluster-randomized design, we will pilot-test the intervention package for feasibility and preliminary effect, as well as cost-effectiveness.  This five-year project is highly feasible considering the multidisciplinary team with skills and experience in both implementation and experimental research, and will contribute much-needed evidence to advance PMTCT care for AGYWs in line with their unique needs.

Syftet med följeforskningen är att öka kunskapen om hur nationella och regionala strategier för stöd och implementering kan bidra vid nationella satsningar - samt att stödja lärandet under den pågående satsningen. Målet är att undersöka, beskriva och dra lärdomar av den implementeringsprocess och de stödstrategier för utveckling och lärande som används på nationell, regional och lokal nivå för att nå ut med satsningen, samt att förstå de valda strategiernas betydelse vid förändring, lärande och hållbarhet i insatser och förändringar efter satsningens slut
