More than one year after the emergence of COVID-19 in the Chinese city of Wuhan, a fact continues to draw the attention of the scientific community engaged in the response to the virus: the lower susceptibility of children to SARS-CoV-2 infection and to the development of severe COVID-19. A number of non-mutually exclusive factors have been mentioned to explain the higher resistance of minors to the virus and its clinical consequences. The purpose of the study was to address an additional factor, so far not much dealt with in the medical bibliography about the topic: unspecific resistance to SARS-CoV-2 could be the result of the vaccines administered during childhood. This analysis is also aimed at contributing a better understanding of the relatively benevolent nature of the virus among children. It is concluded that a number of vaccines administered in childhood, most of them included in the immunization scheme for Cuban children, are associated to a lower incidence and severity of SARS-CoV-2 infection in pediatric ages.
