CDC Study Suggests Vaccination Offers More Protection Against Covid Than Prior Infection
New research published in the Journal of the American Medical Association (JAMA) shows that an increased risk of contracting a devastating disease from vaccination with an ingredient now known to be more dangerous than previously thought should be tempered by evidence that the benefits of vaccination far outweigh the risks. For example, the study showed that vaccination provides up to a sevenfold increase in protection against deadly viral infections. Also, the research showed that vaccination dramatically reduces the risk of developing a crippling disease that infects the limbs and might result in amputation, or dying from pneumonia.
“Previous research on the protective effects of some vaccines showed that the antibodies that our bodies produce against a virus cause us to experience reduced body weight, and possibly lower blood pressure,” said Dr. Emily Storz, assistant professor of internal medicine at the Johns Hopkins University School of Medicine and principal investigator of the CDC Collaborative Study on Vital Signs. “We wanted to know if some of the same types of people benefit the most from vaccines, such as those who already are sick and/or are at risk for severe illness, like babies and toddlers who have underlying health problems.”
Specifically, the study included in-depth examinations of the protective function of vaccines on children with lung and spleen abnormalities caused by damage from viruses and vaccines, as well as on pregnant women and their fetuses. These analyses supported previous estimates that about 47 percent of people who receive high-dose vaccines for MMR or in the same doses that adults receive, experience a significant decrease in lung and spleen abnormalities. Also, the study found that there is a 1.3 to 6.5fold increase in risk of developing certain diseases associated with rabies, such as meningitis and encephalitis, even though those diseases are difficult to transmit during vaccination. (Meningitis can be caused by a host of viruses, such as H1N1 or H3N2, that are not often harmful.)
“Vaccine-related benefits greatly outweigh the risks in preventing potentially deadly diseases, such as pneumonia, meningitis, and encephalitis, which are all usually fatal,” said Dr. Storz. “The findings in our study support vaccine skeptics who continue to deny benefits or take their personal beliefs over knowledge and fear. Evidence is abundant that vaccination is safe, and health officials may need to do a better job educating those who question vaccination to allow them the opportunity to receive the most effective vaccines.”
