Why is this always a thing? Just casually reading the Astra-Zenica Product Information leaflet and when talking about a study it says the control group were given Meningococcal vaccine or Saline. Why not give them all saline? Vaccine studies do this so often I can't remember one that didn't use another vaccine or all the worst bits of the vaccines bar the virus as the "placebo". It's just so stupid I can't believe they get away with it.

Placebo should be sugar, salt or water. No vitamins and no toxins.
