these were never intended to be vaccines. none of the inactivated virus vaccines are approved in the US, not even on EUA.

these are absolutely gene therapy testing at mass scale. they made an injection that alters your body to produce viral proteins, then your body is supposed to produce an antibody reaction to those proteins that is supposed to inhibit the virus providing immunity to a common cold.

the gene therapy took place, bodies producing the viral proteins, but the antibody reaction didn't work out as they claimed, and inhibition/immunity never happened.
