I certainly am not a scientist or in the medical field but my daughter was. It Sounds like the Seattle vaccine tests could be Brilacidin, "to her". The in vivo and in vitro tests would have to have been completed, (in my Daughters opinion) They were, no serious side effects. The fact that Brilacidin has been tested in Humans is heads and shoulders above anything proposed for the market that I'm aware of to date. (OTHER THAN MY HOPES AND OPINION I DON'T KNOW A DAMN THING.)
"Academic Literature Supporting Brilacidin’s Vaccine Potential Against COVID-1 Vaccines containing defensins as adjuvants have been shown, both in vivo and in vitro, to activate the primary innate antiviral immune response and mediate other immunomodulatory activities against a number of viruses, including coronaviruses, such as MERS-CoV.
