Iron Deficiency AnemiaVaccine Preventable Disease2 more

Vaccines often underperform in Africa compared to high-income countries. Why vaccines do not work as well in Africa remains uncertain. Malnutrition likely plays a role. Our study objective is to assess whether iron deficiency anaemia in young women impairs their immune response to viral vaccines, and whether iron treatment improves their response.

DiphtheriaTetanus7 more

This is a randomized cross-sectional study of the Swedish population. Blood samples will be collected from a subpopulation in order to estimate the age specific sero-prevalence of the Swedish population for diseases included in the National Immunization Program (NIP), and to affirm the population's protection against polio. To be able to recommend complementary immunizations to immigrated children, a sub study focusing on foreign born teenagers will also be done and compared to children of the same age born in Sweden.
