I suspect that there will not be a real need for compulsory vaccination of care workers. It would be needed mostly if infection prevalence were to again soar. Current infection prevalence is well under a tenth of its peak in January, it’s still falling, we’re still under restrictions and a majority of workers will get vaccinated voluntarily, many already are.
I know what went on in the care home where a friend of mine works. Staff were complaining of covid symptoms but management were insisting they continue to come in to work. Lateral flow tests were coming up negative until too late; the management may even have deliberately sourced tests with a bad false negative rate just to keep staff working.
The government are making a show of “doing something” when it was the government’s own delay in implementing restrictions, its own failure to control employers, its own failure to hold the press to account that created the problem. So now they’re acting all tough; it’s clear they never learned that effective discipline can only ever start with oneself.
