Dr. Anand Chabra, MD, COVID-19 Vaccination Branch Chief for San Mateo County Health released the following statement:
“With the announcement from the Centers for Disease Control and the Food and Drug Administration regarding concerns about of cerebral venous sinus thrombosis (CVST) in combination with low levels of blood platelets in a small number of Janssen (Johnson & Johnson) vaccine recipients, San Mateo County Health is pausing the use of the Janssen vaccine in all of its operations. County Health has also directed its vaccinating partners, including hospitals and local clinics, to suspend use of the Janssen vaccine until it is officially cleared by CDC/FDA.”
In San Mateo County, a total of 564,367 shots of COVID-19 vaccine have been delivered by San Mateo County Health, health care providers and hospitals, pharmacies, community clinics and other partners. Of the total, 22,306 shots are of the Janssen vaccine. This represents 3.952 percent of total vaccines administered in San Mateo County, the others being the Pfizer and Moderna vaccines.
Over 5,700 doses of Janssen have been used by County Health and its vendors in mass vaccination and community events for all eligible residents, for homeless populations and homebound residents, and in other settings.
San Mateo County Health received 500 Janssen doses this week, which will be held pending further state and federal guidance.
Community clinics with planned use of Janssen will be switched to Pfizer or Moderna. Other initiatives that use Janssen, including vaccination of homebound residents, patients discharged from hospitals, and new bookings at correctional facilities, will be reevaluated.
The County had some targeted events planned with J&J, but has been able to supply those events with available Pfizer and Moderna doses so that those events can still take place at the same number of doses as planned.
