Cleveland Clinic Study Did Not Show Vaccines Increase COVID-19 Risk

Numerous studies have found that additional COVID-19 shots are generally associated with extra protection against the coronavirus. Many people on social media, however, have shared a preliminary finding from a Cleveland Clinic study and misrepresented it as proving that getting more doses increases a person’s risk of infection.

FactChecking Chris Christie’s Presidential Announcement

Former New Jersey Gov. Chris Christie kicked off his campaign for the 2024 GOP presidential nomination with a June 6 town hall in Manchester, New Hampshire.

Ventilators Save Lives, Did Not Cause ‘Nearly All’ COVID-19 Deaths

Ventilators can be lifesaving for critically ill COVID-19 patients.

Ventilator-associated complications can contribute to deaths, but patients are typically put on ventilators when they would otherwise die.

Masking Has Minimal Effects on Respiratory System, Does Not Cause Long COVID

Long COVID is a collection of health problems caused by COVID-19 that remain or appear following the initial infection. It is implausible that face masks cause long COVID, contrary to claims made online. Mask use can temporarily cause discomfort, but physiological effects are not biologically meaningful.

No Evidence Excess Deaths Linked to Vaccines, Contrary to Claims Online

COVID-19 vaccines substantially reduce the risk of dying from COVID-19, and serious side effects are very rare. Excess deaths among working-age adults in 2021 and 2022 were due to COVID-19 and other factors, not vaccination. Faulty logic underlies claims that vaccines caused mass disability and economic harm.
