Marin Looks to Hospitalizations as Decision Metric 

Today, Marin County Public Health announced a new roadmap to inform future COVID-19 mitigation strategies in response to Marin’s high vaccination rate and recent questions about a potential mask mandate. Health officials will focus on COVID-19 hospitalization rates rather than daily case rates as a guide for pandemic response policies and orders. 

Historically, daily case rates of COVID-19 infections have been the primary measure to determine progress and guide policy decisions. While daily case rates will continue to be measured closely, with 85% of the population fully vaccinated, fewer cases are leading to hospitalization or death. In October and November 2020, before the arrival of the vaccine, about 1 in 40 newly diagnosed cases led to hospitalization. Today, that number is closer to 1 in 80.  

“We’re seeing firsthand how vaccines and boosters are protecting us against severe illness,” said Dr. Matt Willis, Marin County Public Health Officer. “When we consider more restrictive policies, it’s a good time to step back and remember our pandemic goals as a community. We’re trying to prevent hospitalizations and death.”  

The new hospitalization-focused metric is already guiding new criteria in Marin. The criteria for potentially reimposing a local mask mandate will be five COVID-19 hospitalizations per 100,000 residents. Locally, that translates to 13 people in the hospital for COVID-19. For context, at the height of a typical flu season in Marin, up to 20 individuals are in the hospital with influenza on any given day.

Boosters for 16- and 17-Year-Olds May Be Available Soon 

Today, both the Food and Drug Administration (FDA) and U.S. Centers for Disease Control and Prevention (CDC) authorized Pfizer BioNTech COVID-19 single-dose boosters for 16-and-17-years-olds who completed their initial Pfizer vaccination series at least six months ago. Previously, Pfizer had been granted Emergency Use Authorization of its booster vaccines for recipients who were at least 18 years old. After reviewing Pfizer’s data, it was concluded that an additional vaccine dose was both safe and effective at maintaining immunity against COVID-19 for this age group. Presently, the age requirement for Moderna and Johnson & Johnson booster shots remains the same at 18 years or older.  

What happens next?  

Before we see the change in age eligibility reflected in California, there is an additional layer of review: The Western States Scientific Safety Review Workgroup (WSSSRW) will conduct an independent analysis of Pfizer’s data. Once they agree to authorize the expansion of age qualification, then California Department of Public Health will implement the changes recommended by the FDC and CDC and provide guidance to Marin Public Health.  

The timetable for the WSSSRW’s review and a final decision is not certain so please stay tuned for updates.  

Please note that online appointment systems such as MyTurn may be delayed a few days at recognizing the change in age eligibility once it’s approved in California.  

Currently, there is extraordinary demand for vaccination appointments by both booster and pediatric vaccine seekers. At the same time, the healthcare industry is experiencing nursing shortages, which affects the pace at which people can be vaccinated. In Marin, an estimated 100,000 people are eligible for and seeking a booster shot. As the eligibility pool continues to grow, rest assured that public health and local medical providers are doing what they can to increase vaccination appointment options soon.
