Key Excerpts

From p. 18 (Table 5. Attendance to emergency care and deaths of confirmed and provisional Delta cases in England by vaccination status):

Total number of unvaccinated cases: 151,054
Total number of unvaccinated fatalities: 253 (205 + 48)
Total number of double-vaccinated cases (i.e., people having received 2 CV shots): 47,008
Total number of double-vaccinated fatalities: 402

Note: Based on these figures, the Case Fatality Rates for this sample population would appear to be as follows (please do your own math):

CFR for unvaccinated cases: 0.167% ([253/151,054] * 100), or 1 in 599

CFR for double-vaccinated cases: 0.855% ([402/47,008] * 100), or 1 in 117
