Since the COVID-19 vaccines were authorized by the FDA, one of the big questions has been how well they prevent transmission of the COVID-19 even among those who have been vaccinated. The clinical trials used disease — an infection with symptoms — as the endpoint because stopping severe disease and death was the most important priority. In addition, it’s very difficult to develop a vaccine that creates sterilizing immunity, the type of immunity that prevents infection — the virus’s ability to enter cells and begin replicating.

Two high-profile safety breaches have highlighted the importance of close adherence to infection control protocols in dental clinics and offices.
In both recent cases, patients have been advised to undergo testing for HIV and hepatitis B and C due to possible exposure to bloodborne pathogens.
In Seattle and nearby Vashon Island, news broke in early April that nearly 1,300 students face infection risks because equipment used in school clinics was improperly sterilized. Ten school-based dental clinics operated by Neighborcare, a local health center have been impacted by the safety breach. Continue reading
Sacramento Bee health reporter Sammy Caiola worked quickly to give her readers the story about the death of a young California father from complications of a dental infection.
Her reporting began at 10 a.m. on Jan. 31 when she found the kernel of the story in an email. By that afternoon, Caiola had tracked down and visited with the man’s grieving widow, interviewed a knowledgeable local dentist on the causes of dental deaths and located peer-reviewed research that added depth and context to her piece.

The recent story of a young California husband and father who died after suffering complications from a dental problem serves as a sad reminder of the important ties between oral health and overall health.
Vadim Anatoliyevich Kondratyuk, 26, a long-haul truck driver, was headed east to New York when he started feeling pain in the lower left side of his mouth.
It is likely that three patients and two volunteers contracted hepatitis B at a large free dental clinic held in 2009 in Berkeley County, W.V., according to investigators.
Investigators documented problems with infection control at the large Mission of Mercy clinic, held at a school gymnasium. But they were unable to definitively link those breaches with the five infections, or to determine exactly how the patients and volunteers were infected. They have shared their conclusions in the October issue of the Journal of the American Dental Association.
The news of the cluster of hepatitis B infections among attendees at the West Virginia clinic attracted wide attention in 2010, after health officials sent out letters notifying hundreds of clinic patients and volunteers that they might have been exposed. The highly infectious hepatitis B virus can lead to serious liver damage. Continue reading
