“ Many more people who got the placebo had symptoms”
Minor cold symptoms - so who cares? Look at the trials reports on severe symptoms. The number of instances are more for placebo, but both arms are minuscule. Scale matters.
"... no cases of severe COVID‑19 were reported in the Moderna COVID‑19 Vaccine group compared with 30 cases reported in the placebo group."
0 is miniscule, 30 isn't.
