Dear Dr xxx -
In response to <hospital>'s demand that all organ transplant recipients receive covid-19 vaccinations, I am removing myself from the organ donor program and urging friends to do the same.
I hope you care that the hospital's decision is already causing harm to patients by decreasing the number of registered organ donors.
Please do your part in rescinding this harmful, short-sighted demand, and hopefully my organs won't go to waste.
Love, Me
You should remove yourself from the organ donation list regardless. The hospitals care more about harvesting your organs than they do keeping you alive.
