Which one would be more efficient in curbing the SARS-COV-2 virus: developing vaccine for the SARS-COV-2 virus, or restoring the innate nonspecific immunity by curing a person’s latent or symbolic metabolic syndromes? Children have a weak immune system, yet they are more healthy without any co-morbidity, so their innate nonspecific immunity is sufficient in coping with the SARS-COV-2 virus.
