TB Vaccine to mitigate COVID infection?

A widely used tuberculosis vaccine is associated with reduced likelihood of contracting COVID-19 (coronavirus), according to a new study by Cedars-Sinai. They found that workers who had received BCG vaccinations in the past-nearly 30% of those studied-were significantly less likely to test positive for SARS-CoV-2 antibodies in their blood or to report having had infections with coronavirus or coronavirus-associated symptoms over the prior six months than those who had not received BCG. These effects were not related to whether workers had received meningococcal, pneumococcal or influenza vaccinations.

While noting that no one believes BCG will be more effective than a specific vaccine for COVID-19, Arditi explained that it could be more quickly approved and made available, given that it has a strong safety profile demonstrated by many years of use. "It is a potentially important bridge that could offer some benefit until we have the most effective and safe COVID19 vaccines made widely available," he said.
