I’ve had my first dose last week ( Astra Zeneca ), very straightforward and no after effects of any substance. Second dose in April.
My consultant on scheduled review said to me they have no data yet on myeloma/ Covid and said they are testing for Covid antibodies on next blood tests for patients who have had the vaccine. I’m 18 months post transplant , on Lenalidomide maint (10mg). Good luck with yours
