You can find a prediction on Google. I entered my details similar to your DH - age 74 and on immunosuppressants - and was given possible date at end of January. Things might even have improved since release of the Oxford vaccine. I hope he gets his soon.
so glad the vaccine is up and running but am just wondering as to how long my husband will have to wait for his, he is 75 but has quite a few underlining health issues, classed as vulnerable, anyone any ideas, has anyone had theirs yet ?
