Honest question, not intended to be a leading question....
Influenza is caused by a virus. We have grown the virus for many years and killed it to be included in flu vaccines. Why can we not do the same for the China variant of the corona virus? Is there a structural or chemical or other reason why we are unable to replicate our previous "successes" and must look for a new approach? Not looking here for the routine answers - big pharma profits, Bill Gates conspiracy, NWO control, etc. Looking for a legitimate bio/med explanation.
One doctor I believe explains the vaccine issue extremely well is Dr. Suzanne Humphries. Please listen to her videos, you won't have any questions after believe me. She also goes into the lie about the polio vaccine as well which is the main thing most pro-vaccine people go on about. She will give you a "bio/med" answer.
