Covid Vaccines Offer Higher Protection Than Natural Immunity


A new study by the CDC showed that COVID vaccination offers stronger protection from virus infection than the natural immunity from previous COVID-19 Infection.

Dr. Rochelle P. Walensky, ditector of the US Centers for Disease Control and Prevention (CDC), said in a statementWe now have additional evidence that reaffirms the importance of COVID-19 vaccines, even if you have had prior infection. This study adds more to the body of knowledge demonstrating the protection of vaccines against severe disease from COVID-19. The best way to stop COVID-19, including the emergence of variants, is with widespread COVID-19 vaccination and with disease prevention actions such as mask wearing, washing hands often, physical distancing, and staying home when sick”.

The study found that unvaccinated people who had prior Covid-19 infection months earlier were 5 times more likely to get COVID-19 than fully vaccinated people who didn’t have a prior infection.

In the Forbes, business writer Joe Walsh highlights the key points of the CDC study.

Forbes: Key Facts from the CDC Study
  • The study looked at thousands of U.S. adults who were hospitalized with Covid-like symptoms in the first nine months of 2021, and either had a prior coronavirus infection three to six months beforehand or took a Pfizer or Moderna vaccine over that timeframe.
  • The unvaccinated and previously infected group was 5.49 times more likely to test positive for the virus again than the vaccinated and uninfected group, the CDC said, after adjusting results for age, region, time and Covid-19 prevalence in the local area.
  • Vaccinated people had better odds than patients with prior infections both before and after the coronavirus’ more contagious delta variant began gripping the country in June.
  • These results line up with a smaller August CDC study that found vaccinated Kentucky residents were 2.34 times less likely to be reinfected with the coronavirus than unvaccinated people in May and June, the CDC noted.
