If they're capable of ignoring benadryl, they're capable of creating fraudulent studies about ivermectin too.
The first fraudulent studies right off the bat were the HCQ study and the ACE inhibitor study from Surgisphere, with completely fabricated data.

You need to be asking yourself: why weren't antihistamines part of the standard of care for COVID, when they were part of the standard of care for all forms of viral pneumonia back in 2016? (Sorry, that's the most recent time period when I had what my doctor at the time thought was viral pneumonia.) Why the Year Zero stuff?
