A scientist known for promoting pseudoscience falsely claims that COVID-19 vaccines are not actually vaccines because they require multiple doses and it’s still possible for vaccinated people to contract and spread COVID-19. Many vaccines require multiple doses and boosters, including polio, measles, HPV, and hepatitis B. No vaccine is 100 percent effective against infection. COVID-19 vaccines dramatically reduce the risk of serious illness and death and boosters provide additional immunity against infection.
