So they’re more than 0% “effective”?
“The ongoing late-stage trial on mRNA-1083 examined the combination shot in 8,000 patients.
The study compared the combination shot with an enhanced flu vaccine called Fluzone HD and Moderna’s currently licensed Covid shot, Spikevax, in one group of patients ages 65 and above. The trial also compared Moderna’s combination jab with a standard flu shot called Fluarix and Spikevax in another group of participants between the ages of 50 and 64.
In both age groups, a single dose of Moderna’s combination vaccine produced “statistically significantly higher” immune responses against three strains of influenza and the Covid omicron variant XBB.1.5.”
This reads as better immune response against 3 flu strains and Omicron XBB.1.5.
This was a Phase 3 test. Harm would be measured in Phase I and apparently they had none that would have prevented moving on to Phase II. I think FDA is the arbiter of Phases in clinical tests. Not sure.
