Results showed that the unvaccinated group was twice as likely to contract the infection again, compared with those who had received one dose of the vaccine.
The findings appear to indicate increased protection from natural immunity over vaccine-conferred immunity. This may be due to a more extensive immune response to the SARS-CoV-2 proteins, compared with the immune activation provided by the vaccine, the researchers suggest.
Infection disease experts warn that the findings should not be viewed as an excuse to forego vaccination. In an interview with MNT, Dr. William Schaffner, a professor of infectious diseases at Vanderbilt University Medical Center, in Nashville, TN, said that the vaccines are doing exactly what they were designed to do.
“All the vaccines we have, Moderna, Pfizer, and [Johnson & Johnson], are very effective in preventing hospitalization — a severity of illness that requires admission to the hospital.”
The researchers behind the new study acknowledge several limitations. Since the Delta variant was dominant during the study period, the findings concerning natural immunity may not apply to infections with other variants of SARS-CoV-2.
