The coivd vaccines have all passed phase 3 trial and like all vaccinations and new medications information is always gathered I would be astounded if it wasn't.
In Australia we have very high vaccinations rates and increasing number of cases from when we started to open up so everyone know the cases would go up but the hospitalization rates are by a big majority the un vaccinated.if we stayed shut down the cases would drop and keep dropping.
Countries like Japan a few months ago at the time of the Olympics had high cases but they are now falling,covid comes in waves and cases number depend on how high the last wave was and the measures each country has in place like NSW they dropped some measures that have now backfired on them. The covid vaccines have saved many from dying from covid and many from being admitted to hospital that would be a disaster for our health system.you are in the minority.
