Doomsday,
Re Placebo’s again: When a NEW vaccine is debuted it is tested with a Placebo not another vaccine.
The only time Placebos (as in totally fake vaccines filled with saline for example) aren’t used is when there is an existing vaccine that has been proven effective and they are testing an IMPROVED vaccine for the same illness. In that situation due to the ethical issues involved with leaving someone unprotected when a safe vaccine already exists they will often use the old safe (but possibly not as effective) vaccine as a placebo.
Vaccines literally DO undergo the same testing as other medicine. You need to stop making up facts and ignoring those facts that don’t fit with your anti science/anti medicine ideology.
