Immunity extends to the manufacture, distribution, administration, or use of medical countermeasures of anti-COVID-19 drugs, vaccines, technology, and devices. This immunity preempts state law. If a person dies from an anit-viral drug or vaccine, no lawsuit can be filed. Everyone from the manufacturer down to the prescribing doctor is exempt from liability. Some of the medications with serious adverse side effects are Chloroquine, Remdesivir, Ribavirin, favipiravir, lopinavir; ritonavir, hydroxychloroquine, Sofosbuvir, corticosteroids, oseltamivir and zanamivir. -GEG
