heres something i nicked off TOF
It was a small but telling illustration of the gap between public expectations of the eagerly-anticipated new COVID-19 vaccines and the long, unpredictable road still ahead.
On Wednesday, federal acting Chief Medical Officer, Professor Paul Kelly, revealed that an “old friend” had emailed to see if his daughter, working in intensive care in Britain, might be allowed to return to Australia without quarantine because she’d received a first dose of the Pfizer-BioBTech vaccine – which British authorities had started rolling out only days before. An “interesting” proposition, Kelly said tactfully.
But let’s return to Kelly’s friend’s daughter. To gain the maximum protection from the Pfizer jab, she’d have to get a second jab three or four weeks after the first (as will also be the case for nearly all the vaccines now under development).
And while that might well protect her from developing the disease of COVID-19 if she caught the virus, it is far from clear whether she’d cease to be an infection risk to others.
Indeed, warns vaccine researcher Professor Peter Richmond from the University of Western Australia, that remains “one of the biggest unknowns – whether these vaccines will interrupt transmission”. And it remains an unknown for all the vaccines now under development, with a definitive answer many months away.
For those dreaming of an “immunity passport” – something that lets you swan through airline check-ins because you can produce proof of having had a shot – the uncertainty about whether you remain potentially infectious once vaccinated is a major impediment. “It’s the cart getting ahead of the horse,” says Richmond. “It’s just too early, we don’t have the data to support how it might work.”
Vaccine anyone?

Yes, the problem with a rushed vaccine is the full spectrum of how it works isn't known.La8rat wrote: ↑Sun Dec 20, 2020 7:36 pmIndeed, warns vaccine researcher Professor Peter Richmond from the University of Western Australia, that remains “one of the biggest unknowns – whether these vaccines will interrupt transmission”.

Regardless, many countries are likely to require vaccination for people coming into the country so that they do not become a burden upon the health system should they contract the disease.
