Data from a trial seeking to determine whether multiple injections of a tuberculosis vaccine developed in the 1900s could protect high-risk diabetes patients from COVID produced some positive results, according to a study in Cell Medicine Reports.

The trial tracked COVID infections among a group of 144 participants all of whom had Type 1 diabetes, with two-thirds receiving at least 3 doses of BCG, or Bacillus-Calmette-Guerin, shots, which protect people by bolstering the immune system, according to the study, as the New York Times reported. 

The results found just 1% of the 96 people who got the BCG shots developed COVID, while 12% of the placebo recipients got the virus.

“The BCG group also displays fewer infectious disease symptoms and lesser severity, and fewer infectious disease events per patient, including COVID-19,” the authors wrote. “There were no BCG-related systemic adverse events. BCG’s broad-based infection protection suggests that it may provide platform protection against new SARS-CoV-2 variants and other pathogens.”

The BCG shots are still given to infants in parts of the world that still have TB cases.

The move comes as U.S. known cases of COVID are continuing to ease, although the true tally is likely higher given how many people are testing at home, where the data are not being collected.

The daily average for new cases stood at 100,747 on Tuesday, according to a New York Times tracker, down 18% from two weeks ago. Cases are falling in almost every state and are down 20% or more in more than a dozen states, namely Rhode Island, Florida, Nebraska, Connecticut, New York, New Mexico, California, Colorado, New Jersey, Idaho, Kansas, Louisiana, South Carolina, Arkansas, Arizona, Wyoming, Hawaii, Alabama, Utah, Oregon and Illinois.

The daily average for hospitalizations was down 45 at 41,668, while the daily average for deaths is up 4% to 467.
