“For the first time, we’re seeing some unfilled appointments in the coming days. If you’ve been waiting your turn, it’s now,” said Dr. Matt Willis, the county’s health officer.

Officials said many health providers are now offering drop-in locations with no appointment necessary. The county’s public health department has also partnered with community based organizations to offer pop-up vaccination sites.

“We’ve made a lot of progress together, and we’re all taking steps to remove any last barriers to access,” said Dr. Mitesh Popat, the CEO of Marin Community Clinics.

Willis said while the high vaccination rate in Marin is encouraging, the county has not yet reached the level of immunity to prevent outbreaks.

“Everyone who gets vaccinated moves us one step closer to putting this pandemic behind us. But we’re not there by a long shot,” he said.
