Factors protecting children

1.Immune system-age related differences in immune systems.

2.Recurrent and concurrent infections-viral and mycoplasma infections.

3.Cross reactive coronavirus antibodies and T cells-exposure to commonly circulating coronaviruses.

4.Microbiota(nasopharyngeal,oropharyngeal,lung and/or GIT)-colonising microbial flora.

5.Melatonin-anti inlammatory and anti oxidative properties.

6.Off target effects of live vaccines-trained immunity from BCG,MCV,OPV.

7.Exposure-intensity of viral exposure.

Simalti Ak

Most symptoms of covid are related to immune dysregulation. reason for this is incomplete clearance of virus and it's the virus debries which acts as target for immune system stimulation. Luckily children tend to clear virus faster and as there's not much debries left after a week, mmune stimulation does not happen hence mild symptoms. Children do suffer from multi systemic inflammatory syndrome (MISC)
