Bruce Harold Lipton is an American writer and lecturer whose work has been dismissed by some peers as pseudoscience.

[7] In 2010, Katherine Ellison wrote in her opinion column in the journal Frontiers in Ecology and the Environment that Lipton "remains on the sidelines of conventional discussions of epigenetics".

[2] In Science-Based Medicine, David Gorski called Lipton a "well-known crank" and likened his idea to the law of attraction, also known as "The Secret": "wanting something badly enough makes it so".

The question of whether [a vaccine] is beneficial or not is now coming to the front because we are finding a very very epidemic increase in regard to allergic reactions or hypersensitivity.

Lipton's apparently anti-vaccine viewpoints contradict the overwhelming scientific consensus, which firmly establishes vaccines' safety and effectiveness in preventing various diseases.
