The science of immunology works both ways. First of all, there is the response provided by our own immune system. Unfortunately it sometimes fails and we will need help. Immunity can also be to our detriment when the immunity is owned by the drug-resistant species of bacteria when conventional antibiotics fail and pathogens have grown resistant.
A reminder about covalent bonded quantum sized atomic silver clusters in an aqueous electric suspension and an effective biocide and able to enhance the immune system prior to penetration of the body by foreign antigens.
