Yes @rechu there seems to be quite a bit of controversy over the Oxford/AstraZeneca. I feel that it may be also to do with the tussle of Britain leaving the EU too, EU are saying they will limit supplies of Pfizer to Britain. It really is awful timing.

I have heard Pfizer works better in older age groups, but much of the trouble is that the trials were limited within older age groups.

I understand about your concerns re volunteering for vaccine trials. I was on the registry to volunteer myself but by the time I got called up (for the Jansen vaccine trial) others were already being given emergency use here. I didn't like the thought of getting a placebo and forgoing my own vaccine chance. I feel guilty saying that but at the end of the day we have to look after ourselves.

My friend is slowly recovering from covid, but she has been very sick. This virus isn't something to underestimate.
