Zambia is a low‐income country on the African continent which is facing a high rate of health inequalities. Although the government has made efforts to reform the organization of healthcare to reduce inequalities, the practical implementation of disability policies remains challenging. Specifically, people with intellectual disabilities (ID) face barriers to accessing healthcare services in Zambia, due to geographic or socioeconomic factors, stigma, and limited specialized health professionals. This perspective paper provides an overview of the current policy and organization on the healthcare provision for people with ID. It presents the key challenges people with ID face in Zambia to access quality healthcare services. Additionally, we provide examples of good practices with a community approach. We discuss policy implementation of disability rights, including access to healthcare, the impact of raising knowledge and awareness about people with ID, and how gathering contextual information through research can help to reduce inequalities. Community and culturally sensitive approaches to improve access to healthcare for people with ID in Zambia are crucial. We call for close collaboration between the fields of research and practice to combine expertise and strengthen the impact and possibilities of scaling good practices within Zambia.

Primary COVID-19 vaccination for children, 5-17 years of age, was offered in the Netherlands at a time when a substantial part of this population had already experienced a SARS-CoV-2 infection. While vaccination has been shown effective, underlying immune responses have not been extensively studied. We studied immune responsiveness to one and/or two doses of primary BNT162b2 mRNA vaccination and compared the humoral and cellular immune response in children with and without a preceding infection. Antibodies targeting the original SARS-CoV-2 Spike or Omicron Spike were measured by multiplex immunoassay. B-cell and Tcell responses were investigated using enzyme-linked immunosorbent spot (ELISpot) assays. The activation of CD4+ and CD8+ T cells was studied by flowcytometry. Primary vaccination induced both a humoral and cellular adaptive response in naive children. These responses were stronger in those with a history of infection prior to vaccination. A second vaccine dose did not further boost antibody levels in those who previously experienced an infection. Infection-induced responsiveness prior to vaccination was mainly detected in CD8+ T cells, while vaccineinduced T-cell responses were mostly by CD4+ T cells. Thus, SARS-CoV-2 infection prior to vaccination enhances adaptive cellular and humoral immune responses to primary COVID-19 vaccination in children. As most children are now expected to contract infection before the age of five, the impact of infection-induced immunity in children is of high relevance. Therefore, considering natural infection as a priming immunogen that enhances subsequent vaccine-responsiveness may help decision-making on the number and timing of vaccine doses.
