findings suggest people who recovered from the virus should still receive vaccines. A nationwide study from the Centers for Disease Control and Prevention (CDC) shows that mRNA COVID-19 vaccines are associated with significantly more immunity than a prior COVID-19 infection.
Researchers from the CDC’s VISION Network gathered data from more than 201,000 hospitalizations in nine different states. About 7,000 people in that group fit the criteria for this study. The research team analyzed the number of unvaccinated individuals who had a positive COVID-19 test more than three months before being hospitalized for the virus as well as the number of individuals who received the Pfizer or Moderna vaccine and were not diagnosed with COVID prior to being admitted to the hospital. The research team found that overall, unvaccinated adults with a previous COVID-19 infection were about five times more likely to be hospitalized than those who were vaccinated.
