The history of infections to unrelated pathogens can modify the protective pathogen-specific memory stored in activated lymphocytes. In consecutive infections by Plasmodium and other viruses positive and negative effects against the immune memory established by natural infection or vaccines was reported. In subsequent infections by vaccinia virus, lymphocytic choriomeningitis and murine hepatitis an exhaustion of the Plasmodium berghei-specific memory was associated with the loss of CD8+ T lymphocytes. On the other hand, a previous infection or coinfection with Plasmodium supresses pathologies induced by the Chikungunya virus reducing joint inflammation and viremia produced. Malaria-endemic regions report a lower incidence and mortality by SARS-CoV-2. It is hypothesized that populations with a history of longstanding exposure to malaria would have natural immunity against COVID-19. The differentiation, activation, and expression of co-inhibitors of T lymphocytes has been compared between mono infections of SARS-CoV-2 and Plasmodium falciparum. Nonetheless, no information about SARS-CoV-2 and mono infections or consecutive infections by Plasmodium vivax, dominant species in Latin America, have yet to be published. In the local context, Loreto is affected by malaria and COVID-19 and in this region is where the highest incidence and prevalence of P. vivax infections is registered and lower than national averages of incidence, mortality and lethality by COVID-19 were registered. In this population the effect of P. vivax infections after an infection by or vaccination against SARS-CoV-2 and the reverse sequence on the presence of memory T lymphocyte subpopulations will be evaluated. This exploration of the heterologous immunity between P. vivax and 4 SARS-CoV-2 will create new knowledge about the interaction between parasitic and respiratory viral infections. Specifically, if it exists, the immunomodulation of the immune response against P. vivax in whom have suffered a previous infection by or have been vaccinated against SARS-CoV-2 and vice versa will be characterized.
