COVID 19 jab

I've always been provax but I must admit to hesitancy with this one.  I don't feel particularly at risk at the moment (but we know that may change at any time).  I've had enough health issues to last me a lifetime and supposedly at over 50 with a weaker immune system I am vulnerable but I'm being expected to have a vaccine with lower efficacy that has been questioned by health experts in other countries.  Not particularly convinced but will discuss it with my oncologist next week, and more than likely join @arpie on the fence for awhile.
