Coronavirus infection in children vaccinated against respiratory infections
The article presents the differences in the course of coronavirus infection in children depending on vaccination against respiratory infections (influenza and pneumococcus). It was found that in the absence of vaccination against respiratory infections, severe and moderate course of COVID-19 infection is observed more often. Vaccination against respiratory infections prevents the development of a severe course of the new coronavirus infection. It was noted that the pneumococcal vaccine does not create protection against COVID-19, but it prevents superinfection and the development of severe forms of bacterial pneumonia. The flu vaccine forms early cross-immunity between influenza and coronavirus infection, thus preventing the development of a severe course of the disease.
