Less than 1 in 1,000 people who have been vaccinated or previously infected with COVID-19 have been hospitalized with a new infection, a Mayo Clinic study has found. The study, published in Clinical diseasessupports previous research showing that vaccination is the best way to prevent serious COVID-19 infection, hospitalization and death.

“In the majority of primary care patients, those who are vaccinated have a lower clinical risk for future COVID-19 success,” said lead author Benjamin Pollock, Ph.D., explorer in the Mayo Clinic Robert D. and Patricia E. Kern Center for Health Sciences. “Our research shows that although it can and does happen, these things are not uncommon.”

Researchers have created another long study of 106,349 primary care patients at the Mayo Clinic in Rochester who are 18 years of age or older and have tested positive for COVID-19, and / or have been injected COVID-19. Of those patients, only 69 were hospitalized due to the development of COVID-19 infection.

The researchers found that the number of hospitalizations was:

  • 0.06%, or 6 out of 10,000 for patients who have been vaccinated.
  • 0.03%, or 3 out of 10,000, in people who have had the disease in the past but have not been vaccinated.
  • 0.01%, or 1 in 10,000, of those who have been vaccinated against a previous infection.

While there were few differences between the three groups, the researchers noted that the differences were not statistically significant.

“We found these results to be consistent with previous studies, although the interpretation should not be so. natural immunity Dr. Pollock says it offers the same protection as the vaccine. “Instead, this study found that in the population of our first population, natural immunity and immunosuppression appeared to result in a decrease in clinical value.”

The researchers looked at developmental factors that led to the clinic, but did not compare immunization after infection with the number of vaccines between simple or asymptomatic cases.

“We know that prevention is the safest way to protect against COVID-19 infection as well severe disease, “said Aaron Tande, MD, a Mayo Clinic physician and co-author of the study.” I explained to my patients that COVID-19 provides additional protection, even if they have been infected in the past. For those who are not infected, prevention is the safest and safest way through protection. “

Previous studies have shown similar results, the researchers noted. Some studies have shown that immunization after infection prevents most hospitalizations. Other studies have shown that vaccination prevents most hospitalizations. In both cases, clinical success is rarely achieved.

“Because it is impossible to predict in advance what the initial infection may be, or who among the vulnerable the virus could spread to, waiting for immunization is a game and not a safe alternative,” he said. from Dr. Tande.
