New CDC Study: Vaccination offers higher protection than previous COVID-19 infection

Nov. 1, 2021

The CDC has published new science reinforcing that vaccination is the best protection against COVID-19. In a new MMWR examining more than 7,000 people across 9 states who were hospitalized with COVID-like illness, CDC found that those who were unvaccinated and had a recent infection were 5 times more likely to have COVID-19 than those who were recently fully vaccinated and did not have a prior infection.

The data demonstrate, according to a release from the CDC, that vaccination can provide a higher, more robust, and more consistent level of immunity to protect people from hospitalization for COVID-19 than infection alone for at least 6 months.

The study looked at data from the VISION Network that showed among adults hospitalized with symptoms similar to COVID-19, unvaccinated people with prior infection within 3-6 months were 5.49 times more likely to have laboratory-confirmed COVID-19 than those who were fully vaccinated within 3-6 months with mRNA (Pfizer or Moderna) COVID-19 vaccines. The study was conducted across 187 hospitals.

COVID-19 vaccines are safe and effective. They prevent severe illness, hospitalization, and death. CDC continues to recommend everyone 12 and older get vaccinated against COVID-19.
