The average lay person has no idea what determines true efficacy. To label an experimental modality the way its being marketed borders on criminal behavior. Just because you can do something doesn't mean you should. If enough people end up being hurt or killed the blow back will be extreme.
The whole process will undermine the physician-patient relationship for years. Welcome to the low trust society.
The average lay person understands that if you visit Guinea you'll need the Ebola vaccine along with other shots. They understand why they don't need an Ebola shot otherwise. They can evaluate their own risks of getting and spreading COVID. They need more information, not less. I want to give them all the information. You want to withhold information like vaccine efficacy.
