The WHO Vaccine Safety Summit – from someone who was actually there

Helen Petousis Harris Jan 14, 2020

The conspiracy I saw a new conspiracy theory flying around the other day. According to the conspiracy (that seems to originate from Del Bigtree), the World Health Organization have been ‘caught on camera’ questioning the safety of vaccines.

We have had vaccines for about 80 years but this disease is defiant in the face of human immunity. I wanted to address some misconceptions about pertussis vaccines. Seven key points in … Read More

Why are vaccinated people getting measles?

There are four reasons for this – … Read More

Authentic resistance or authentic distortion?

Helen Petousis Harris Aug 05, 2019

Authentic resistance appears to be a two woman army advocating that the body’s natural immune system is all that is required to keep healthy. They assert that parents must make an informed decision about vaccines based on information from the medical literature. On the latter point we agree. The Resistance is holding seminars around the country on “Informed consent and … Read More
