Recently both Pfizer and Moderna announced they were developing a combination injection utilizing mRNA coding for the BA4/BA5 Omicron subvariant and new mRNA coding for antigens contained in the influenza virus.[i] Because the COVID-19 component is under Emergency Use Authorization, has failed in animal studies and no human trials have been reported, that component should be off the table from the start. A recent paper from Chemaitelly and colleagues demonstrated in the Omicron era, COVID-19 boosters had unacceptably low protection against acquiring the infection and no valid study has ever demonstrated reductions in hospitalizations and deaths.
Combining the genetic code for both the SARS-CoV-2 Spike protein and conserved proteins of influenza A and B would mean installation of the long-lasting genetic code for multiple foreign proteins in the human body. Production of these proteins will induce an ongoing multi-pronged immune response which is likely to create amplified side effects, above and beyond each component alone, rendering even greater incapacitation than we have seen with the COVID-19 vaccine alone.link
