I am in treatment for Cancer related issues. My oncologist wants to know every thing I ingest. I have an approved list of stuff for nausea , tremors, sleep and constipation. Any otc drug of any kind ,she requests approval. I casually asked her about the vaccine and she rolled her eyes and said, we are working with expensive, precisely tested and known drugs in your body, I am not going to introduce a wild card into the mix........ So no vaccine for me until at least April of 2022...... if then!
