Britain had the Common Cold Research Unit for decades trying to find a vaccine and/or cure. Human coronaviruses responsible for some Colds were first identified here. Volunteers were infected with Cold viruses and various things tried on them. In 1989 the Unit shut down as it had been impossible to develop vaccines or cure for these coronavirus and other Cold viruses.
Influenza vaccines have been around for 80 years with overall poor results. We still have Winter ‘flu epidemics every year of varying severity, millions get it, thousands, sometimes tens of thousands die every year. These viruses just mutate too quickly.
I think this knowledge tilted the pharma companies to gene therapy ‘vaccines’ as they knew normal vaccines made from the virus stood little chance of any substantial effectiveness. And what a great opportunity to experiment on the World population without the expense and hindrance of ethical clearance, years of animal testing, regulatory work-up and careful Human phase testing.
The truth is the gene therapy, doesn’t work either for the same reasons normal respiratory virus vaccines don’t. The viruses are too fleet of foot; mutations too numerous, too fast evolving.
Having been involved in the medical arena for 30 years, an insider’s knowledge, I never had ‘flu vax nor have had or will have the SARS CoV 2 pseudo-vaccines on the grounds that I am exposing myself to an unnecessary risk - don’t care how slight - (extent as yet unknown with the gene therapy) and on the grounds of being at little risk from the actual disease contractable from multiple different viruses and mutations (so immunising against one virus won’t stop me getting the disease from another), and the unlikelihood the vaccine would offer me any greater protection than my immune system on its own after a lifetime of exposure to coronavirus, influenza and other respiratory virus.
