More should be done to increase take up but employers are a bit hamstrung in the measure they can take because of big staff vacancies. Brexit might make this worse
Employers can make reasonable demands on employees these days for example in certain professions concerning things like smoking and drinking and the wearing of certain clothing , grooming etc even in an office or retail environment.
Just like all people with symptoms would be encouraged to come forward and have a test for covid all staff can be requested to come forward and be vaccinated at designated hubs and centres etc.
the most important people to vaccinate are those at highest risk and they should be given preference.
then you move through the population.
Even when as many as can be are vaccinated and may require boosters with the passage of time like influenza for example you will still have cases and spread but hopefully good anti viral treatment like some which are proving already to increase the immunity to fight off the disease in elderly people taken with zinc upon early onset along with good quarantine tracing and protective measures with prevention will ensure like can on as normal as before without the requirement for further lockdowns which do a lot more damage to mental health , prevention of diagnosis for many other diseases , the economy , lives , livelihoods and social norms and democracy and basic freedoms than the damage caused by covid.
