Dr. Campbell used to be pro the covid vaccine, having taken the vaccine himself. He has since realized that all of us, including himself, were all lied to. He has since been on a crusade to pursue the truth.
In the above video, Dr. Campbell brings up video clips of the heads of Pfizer and Moderna being asked by governments (US and Australia) about the link between the covid vaccine and heart problems. However, the videos clearly show how the leaders from both Pfizer & Moderna continue to lie to governments and to the public.
