The thing is though @bumbleymummy, what exactly is low risk? I've felt low risk all along from coronavirus but I feel my chances of dying or becoming seriously unwell from coronavirus are much higher than the AZ vaccine. That's how I feel with regards to the vaccines.
When it comes to the prioritisation, the most vulnerable now have a really good level of protection from one dose. How many 'low risk' people would die of coronavirus, particularly as society begins to reopen (which it absolutely has to, for everyone's mental, the economy- particularly the jobs of the low risk people)? It may be a small number of deaths but for one I think it would be a lot more than the deaths caused by any vaccine and in addition, it's the impact of these deaths that should be considered. People in their 20s, 30s and 40s who have children, where the impact would be hideous if something happened to their parents.
I think it's a good thing to get the first dose into as many as possible- the rollout of first doses has slowed to take into account the second doses required which is obviously right but I think the way the UK rolled the vaccine out has saved more lives than if we'd just stuck to getting two doses to the earliest recipients of the vaccine. It is what it is now anyway I guess. I'm just concerned as to what will happen to me getting my second dose of AZ if they change the recommendations to only offering AZ to over 40s but presume if you've had your first dose they'll give you the second? Hope so anyway.
