Medical Experts Skeptical of Doctor’s Claim to Have ‘Home Brew’ COVID-19 Vaccine

Experts are warning people not to take homemade COVID-19 vaccines, especially given their lack of testing in large clinical settings. But biologist Preston Estep says he has developed a COVID-19 vaccine nasal spray, and that he has administered it on himself, his son and other volunteers. Estep says he concocted the vaccine in a borrowed lab, and took several weeks, using various ingredients commonly available to scientists who work on vaccines.
