^Vaccinating older people, who can shield themselves at home, will be less effective at halting transmission.^
You state that, Ellianne, as if it was fact. Given that we don't yet know whether the vaccine reduces transmission or reduces the symptoms and effects of the virus, its not something you can say. Especially if you are not trained in epidemiology.
Exactly! We don't even know yet how long any immunity will last because it's far too early to say.
After people have been vaccinated, they will still need to stay safe. The scientific and statistics bods will then monitor the people who have been vaccinated to see whether they develop symptoms.
It will be many months before anybody knows if the immunity is long-term or permanent.
I would imagine that's the rationale behind giving it to the most vulnerable - at least it should help with saving lives. If younger, more socially active people were vaccinated, they might think that it's safe to go back to life as normal.
