No, not wary based on what have read and heard. Though contacts I know a bit about the process and how this has managed to be speeded up due to combined efforts and increased funding, and the fact that they weren't starting from scratch.
I've also had Covid and over six weeks later I've had my first day back at work, after being rather poorly, including a hospital stay and now have long term complications and will most likely need to take medication for life as a result.
I'm clinically vulnerable and already have an annual flu jab. My work place is fairly high risk - school where there is no social distancing, no masks, etc and it's where I almost certainly caught Covid. No one can guarantee I have immunity from it, if I do for how long and if I could catch it again.
I can't do this again. To be honest, with my (newly acquired due to Covid) blood pressure and heart rate complications, I'm not sure my body would react to it all over again and starting in an even worse position.
I'll take any vaccine they're offering me as soon as it possible. If it was possible to pay for it to have it sooner I would do so.
Dh and 18y Dd are both happy to have it. Neither are vulnerable but neither want it, not want to risk passing it on to others who are more vulnerable.
