Speaking of herd immunity.............
"The International Council of Nurses (ICN) has revealed that a total of 1,500 nurses across 44 countries are believed to have lost their lives to Coronavirus."
OK, that is 1500 / 44 = 34 nurses per country.
The UK has half a million nurses, so 34/0.5m = 0.0068% have died of Coronavirus, while 0.068% of the total population have died of Coronavirus, so nurses have 1/10th the death rate of the average person...
Of course any death is bad, but if nurses are dying at similar rates as people in other professions then the headline is very misleading, and there is no reason to compare it with the WW1 figure which included deaths from Spanish Flu and accidents among the 1500 global deaths!
come to think of it haven't seen any mention of herd immunity among frontline health workers, only how dangerous it is for them

might be busy with a patient right now, will have to wait
Earlier in the year, IIRC there was a UK study that found that doctors and nurses had roughly the same rate of infection as others, didn't get reported much because it wasn't the result the press wanted for their headlines and wasn't what they had been reporting in previous months where every death of a healthcare worker was counted and published as shocking statistics.
Since then a lot of our healthcare workers have been vaccinated as part of the trials so I guess they now have a lower infection rate than average. I would also expect healthcare workers in covid wards to be selected from those known to have some level of immunity.
No patient in the covid ward has immunity or they wouldn't be there, thus herd immunity does not work there, although no patient in the covid ward is capable of catching covid since they already have it, so the infection rate among patients should be very low! By now the immunity of the healthcare workers for covid wards should be very high, hopefully due to immunisation and selection, so again the covid ward should have low danger as long as it is kept isolated from outsiders.
In the rest of the hospital the normal herd immunity for the whole community applies with the exception that many of the healthcare workers have far more daily contacts than the average person, so they have a much higher chance of being infected if they haven't been immunised, however most of those contacts are short, giving them more chance of a minor or asymptomatic infection.
The
big problem in hospitals is spread of covid among non-covid patients and the apparent inability of the hospitals to keep patients isolated, 25% of covid cases in hospital being a result of hospital caught infections is shocking:

Liverpool University Hospitals NHS Foundation Trust has also exhibited a growing problem with probable HCAIs. While the trust continues to show persistently high total numbers of new patients in hospital with COVID-19 – a 7-day average of around 40 per day – admissions from the community have slowly fallen from a peak of around 31 per day on the 7th October. This general slow fall in community admissions has been masked in the aggregate, however, by an increase in probable HCAIs that began in early October, and peaked at around 13 per day in the most recent week of reporting. In the last week of reporting, probable Hospital Caught Infections made up 27% of all new patients in hospital with COVID-19.
