What's the general feeling on here regarding the vaccination program impact on infection rates, hospitalisation numbers and death rates in, say, the next month or so?
In the next month the death rates are, sadly, more or less 'baked in'. However on a 2 month view I reckon the reduction in death rates due to vaccination (of at least one dose by today (13 Jan) will be significant. I think one of John Campbell's videos estimated 6,000 less deaths by 1 April, with an optimistic roll-out and delivery of the programme. Since this reduction would be spread roughly and increasing over Feb and March, this might be -50 on 1 Feb rising to -200 by 1 Apr.
On hospitalisation numbers, I think the vaccination programme will have a progressively beneficial effect (I bloody well hope so). These very recent PHE graphs:
The hospitalisations graph shows there's about an equal number of over 85s and under 85s admitted. By 1 Feb it'd reasonable to assume that every over 85 has had (or at least been offered, don't know what the take up is) the first dose and had 12 days to develop 80% resistance to infection and 80% will therefore not get infected and those that do (no vaccine gives complete assurance of immunity) will experience less severe symptoms, hopefully keeping many of that remaining 20% not needing treatment in hospital. So might we assume that (due to vaccination) admissions to hospital (due to COVID-19) of over 85s will be cut by 90+%?
On infection rates, only a small percentage of those testing positive for COVID-19 are over 80, so the effect
of the vaccination programme (NB first dose + 12 days) will be very limited in the next month and be dwarfed by the effect of improved (enforced) reduction in risk of infection behavior by the population.
