Snohomish County health officials said on Nov. 4 that all mass H1N1 vaccination clinics scheduled for November have been cancelled.

Limited supplies of vaccine will instead be diverted to participating Snohomish County medical providers whose patients are at “high risk” of complications from H1N1 influenza, according to a county release.

The Snohomish County Health District began distributing vaccine to participating doctors’ offices Nov. 4, starting with providers who are registered with the state Vaccine for Children program.
