San Diego County declares medical misinformation a public health crisis
San Diego has become the first county in the U.S. to declare that health misinformation is causing a public health crisis in its community. This follows the County Board of Supervisors' 3-2 vote Tuesday night.
Changes to county strategy to combat the pandemic will include: labeling health misinformation and providing timely health information to counter it; modernizing public health communications; investigating in digital resources and training for health practitioners and health workers; and developing a website to be a central resource for fighting health misinformation.
The new policy was introduced when 96.7% of hospitalizations in San Diego County were residents who were not fully vaccinated.

KISS co-lead singer Gene Simmons tested positive for COVID-19, the band shared on its Twitter page Tuesday evening.
In a statement, the band said the 72-year-old was experiencing "mild symptoms."
His diagnoses comes less than a week after co-lead singer Paul Stanley, 69, tested positive for COVID-19 as well.
In a statement released on Aug. 26, the band said that, "everyone on the entire tour, both band and crew, are fully vaccinated."
KISS has postponed four of its "End of the Road" tour shows from Sept. 1 to Sept. 5.
"The band and crew will remain at home and isolate for the next 10 days," the band said in a statement.
2 officials working on COVID-19 vaccine review to leave FDA
Peter Marks, the director of the Food and Drug Administration's Center for Biologics Evaluation and Research (CBER), announced the upcoming departure of two top vaccine regulators to his staff in an internal memo, which was obtained by ABC News.
Dr. Marion Gruber, director of the FDA's Office of Vaccines Research and Review (OVRR) and her deputy, Dr. Phil Krause, are set to leave the agency in October and November respectively, according to the memo.
Krause, who's been with the agency for over a decade, and Gruber, who has been with the FDA for over 30 years, were instrumental in the review and authorization of the three COVID-19 vaccines, the memo said.
The memo said that Gruber will be "retiring" and gave no other details about Krause's departure.
ABC News has reached out to both Gruber and Krause for comment.
When reached for comment about their departure, an FDA spokesperson told ABC News the agency is "confident in the expertise and ability of our staff to continue our critical public health work, including evaluating COVID-19 vaccines."
Their departures come at a critical time for the vaccine review team. After facing pressure to move as fast as possible to get vaccines' full licensure done, the agency is now weighing booster shots for a wider pool of Americans.
The timing of the booster shot approval has been a bone of contention amongst federal agencies after the Biden administration announced the availability of booster shots would begin ahead of any ruling from the FDA or Centers for Disease Control and Prevention advisory groups.

Pediatric hospitalizations nearly 4 times higher in states with low vaccination: CDC
Two studies to be published Friday found fewer pediatric hospitalizations among children and communities with higher vaccination rates, the director of the U.S. Centers for Disease Control and Prevention said.
In one study, national data from August showed that children were nearly four times more likely to be hospitalized with COVID-19 in the states with the lowest vaccination rates when compared to states with the highest rates -- proof that "cocooning" children with vaccinated people keeps them safe, Dr. Rochelle Walensky said at a White House briefing Thursday.
The second study, which looked at hospitalizations rates in 12- to 17-year-olds across 14 states during July, found that adolescents who were unvaccinated were 10 times more likely to be hospitalized with COVID-19 than their fully vaccinated peers, Walensky said.
"Both studies, one thing is clear: cases, emergency room visits and hospitalizations are much lower among children and communities with higher vaccination rates," Walensky said. "We must come together to ensure that our children, indeed, our future, remain safe and healthy during this time."
