Marin Moves Forward with Moderna Doses

State greenlights use of vaccine lot, signals confidence in safety

San Rafael, CA – Marin County health care providers have been given the green light to proceed with distribution of all Moderna vaccine doses on hand, including the lot that had been placed on hold last week pending investigation.  

A rigorous epidemiological review by California Department of Public Health, the Western States Scientific Safety Review Workgroup and the U.S. Centers for Disease Control and Prevention determined the observed reactions were associated with only one site, a clinic in San Diego, and not with this lot of vaccine.

In the first month of distribution, the Moderna vaccine has demonstrated to be both safe and effective. Northern California has extensive experience with this vaccine, including thousands of doses from the temporarily “paused” lot administered prior to the San Diego event.

Vaccine supply determines the pace at which we’re able to vaccinate our community. For Marin County, this news from CDPH means 2,540 more people in Marin County can safely move forward with receiving their first dose of this vaccine. This represents approximately 9.5% of the total supply Marin County Public Health and local hospitals have receive thus far. We’re hopeful the supply chain will increase soon so we can begin to expand the numbers of people vaccinated each week.

"These findings should continue to give everyone confidence that vaccines are safe and effective and that the systems put in place to ensure vaccine safety are rigorous and science-based,” said Dr. Matt Willis, Public Health Officer. “The Moderna and Pfizer COVID-19 vaccines are some of the most effective vaccines ever produced, and I encourage all Marin residents to seek the vaccine when it’s their turn.”
