This is true, though anything that gets transmission down will reduce the impact of such absences.If teaching is anything like my workplace then most covid related absences are caused by someone being told to self isolate as a result of being a close contact rather than testing positive themselves. Vaccination won't currently solve this issue.
Some countries are focussing on key workers (and in the case of a country like Australia they are focusing on prioritising staff who may contact with people who have arrived from abroad, which makes total sense) on the basis that the vaccines will primarily be used to reduce transmission, initially. I think that may be the best approach for countries with very low levels of the virus.
I think the UK could have done a hybrid of key workers + by health condition + by age but it would have been very complex and given how endemic the virus already was at the start of the programme, I think the best decision has been taken for us, while other countries adopting a very different approach may well be doing what is best for them.
Yes you couldn't make this stuff up if you tried! It's insane.In the papers today...80% (Eighty percent) of the AZ vaccine in Mainland Europe is unused ! seems they do not trust the AZ vaccine, yet all that fuss they made about the UK not letting them have their fair share !
Macron and others are to blame for this.
