Gates Tries to Justify Side Effects of Fast-Tracked Vaccine Story at-a-glance Bill Gates warns you will probably need multiple doses of any given COVID-19 vaccine for it to be effective The Moderna COVID-19 vaccine (currently known only as mRNA-1273), caused systemic side effects in 80% of Phase 1 participants receiving the 100 microgram (mcg) dose Side effects ranged from fatigue (80%), chills (80%), headache (60%) and myalgia or muscle pain (53%). After the second dose, 100% of participants in the 100-mcg group experienced side effects In the 250-mcg dose group, 100% of participants suffered side effects after both the first and second doses. Three of the 14 participants (21%) in the 250-mcg group suffered “one or more severe events” According to Gates, the side effects are largely due to the high dosages Moderna had to use to achieve the desired antibody levels. But if high dosages are required to create a robust-enough immune response, and higher dosages also cause systemic side effects in most or all people, the safety of the global vaccination campaign may be questionable "Studies have suggested that coronavirus vaccines carry the risk of what is known as vaccine enhancement, where instead of protecting against infection, the vaccine can actually make the disease worse when a vaccinated person is infected with the virus."
