2 key factors:If your survival rate for COVID is 99.7%, what's the logic behind vaccinating all age groups for that, especially since the vast majority of the deaths are in older people with 1 or more comorbidities?
How much does your survival rate improve to if you take Pfizer's 94% efficacy for example?
1) Death statistics include benefit of 2/3 of the population now vaccinated in the averages, for which death/hospitalization rates are minuscule compared to unvaxxed. So I’d triple the rate to ~1% chance of death by being unvaxxed
2) For every death, ~4 get serious enough symptoms to be hospitalized - many of whom have long term symptoms.
So to avoid a 5% chance of hospitalization or death, get a free and risk-free shot. And help keep our hospital workers sane, and reduce the chance of becoming a carrier that kills off a friend or family member.
Also, while deaths are indeed concentrated in the elderly, severe COVID leading to hospitalization is more evenly spread.
Alternatively, if I accepted a hypothesis of only 0.3% death rate for a specific person, I’d still include a minimum of additional 1-2% chance of a severe COVID leading to hospitalization and possible long term health effects (on average a factor of 4 higher, but as implied above, this ratio is much higher for younger folks). Both of which can be reduced by a factor of 10 or so via vaccination.
