So the aim of vaccinating front line NHS staff is to reduce sickness absence and maintain service continuity. In our example of an acute trust that kind of works since we've established that every single member of staff is front line but that's not by design, it's by default since they all work in the same building in which it is possible they will come into contact with patients. I don't think that staff falling into the front line category by default is really acceptable though when you're planning a strategic vaccination program.
What we haven't done is define as front line the staff who, regardless of patient contact, are essential to the running of the service. If the aim of vaccination is service continuity then these people also need to be defined as front line since without them the entire service grinds to a halt. And that's a lot of people in a lot of professions. We are way, way past just doctors and nurses as suggested upthread.
If we take a military analogy, which 'front line' lends itself to, then the other essential staff are still support staff, however essential, so we need a more nuanced approach to strategy.
Part of that, in my opinion (and a bit off topic) is giving practical workers more direction as to admin and its priorities.
Bringing it back to planning a strategic vaccination programme, public enthusiasm for vaccination has to be tempered by developments and informed by good research. The research for first wave vaccination was rushed but thorough enough and well debated. Then we sat back and assumed it was done and dusted, despite virus mutation always having been inevitable.
It seems from widespread observation and research that covid vaccination does not prevent infection, it moderates symptoms, and as things stand its effectiveness against the new Omicron is at best 'not proven'. So a thinking person, and I hope I am one, can reasonably decide that though vaccination last spring and summer was highly desirable with caution to study patients' allergic and other negative reactions, the situation has now changed with regard to booster shots of the original vaccines. Fortunately, consistent with informed predictions, the mutation we face now seems to be less virulent.
In this view makes me 'anti-vax' in the popular view so be it, but I hope not, because it's not a simple yes/no issue.
