28 pages in and people still aren't getting the point of this initial wave of vaccinations.
It's not about saving specific lives etc. It's about preventing the NHS from being overwhelmed so that everyone who needs a bed can get one.
From a statistical point of view, the elderly are the most likely to be hospitalised, over those younger people with heath conditions. So they are vaccinated first to prevent them overwhelming the system.
Care homes need to be able to take residents from hospitals. Their residents are vaccinated because if care homes have outbreaks they cannot take more residents from hospitals, and then hospitals get overwhelmed with bed blocking on a mass scale.
Health staff are vaccinated because if they can't treat anyone, the system gets (drumroll)... overwhelmed and can't treat anyone.
These groups have been selected because it's the most efficient way to ensure that if you happen to be a clinically vulnerable person, or a teacher, or a child, then there will be a bed available for you because the system won't have been overwhelmed by those groups who are statistically more likely to have needed beds.
Once the initial programme is set up, I expect we will see new programmes with more people able to access one, in the same way we have with the flu vaccines. But in the meantime, steps have to be taken to ensure our health system continues to function, and this is the best way.
