Differential pre-pandemic breast milk IgA reactivity against SARS-CoV-2 and circulating human coronaviruses in Ugandan and American mothers

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread worldwide causing> 177,100,000 coronavirus disease 2019 (COVID-19) cases by June 18, 2021(World Health Organization, 2021). Uganda, like other African countries, has registered fewer COVID-19 cases and deaths per capita than non-African countries (World Health Organization, 2021). The lower numbers of cases and deaths in Africa by comparison with those in Western countries might be partly due to cross-immunity induced by circulating common cold human corona viruses (HCoVs) (Doshi, 2020).
