In addition to the continuing COVID-19 pandemic and the omicron wave, the flu season is also upon us. As we have already learned, the RNA/DNA vaccines have severe limitations in preventing coronavirus infections, emerging viral mutants and their spread, and seasonal anti-flu vaccines cannot keep up with the viral mutations. It is difficult to protect ourselves from every single infectious agent unless our own immunity is strong. Most of the antivirals weaken the immune system and cause other side effects. It is critical to address the fundamental mechanisms of infection and increase the immunity of the human population.
