Lets assume the number of counted active cases at the peak is 70% of the actual active cases at the peak.Assuming the asymptomatic knew to get a test done and thus be included in the positive case numbers.
The new hopsitalisation rate (unvaccinated) is 0.7 * 0.015 = 1.05%
Total hopsitalisations in 25 million = 262,500
Hopsitalisation rate (AZ) = 0.08%
80% vax rate hopsitalisations = 68,500
100% = 20,000
Hospitalisation rate (Pfizer) = 0.04%
80% vax rate hospitalisations = 60,500
100% = 10,000
