INFLUENZA AND INFECTIOUS DISEASE FORUM JULY 29, 2010 ERIN BACHUS, ADULT IMMUNIZATION COORDINATOR COMMUNICABLE DISEASE CONTROL AND PREVENTION SAN FRANCISCO DEPARTMENT OF PUBLIC HEALTH Flu Season Vaccine Update

A blast from the past: Lessons learned about H1N1 Vaccine Distribution Vaccine distribution was divided into phases  Phase 1 (mid-October): Limited doses available, focused only on providers serving primarily priority groups – based on how provider registered (Ob/Gyn, Pediatrics, Family Practice, Hospital, etc.)  Strategy: decrease each order by the same percentage based on total number of doses available for each type of vaccine Best option since SFDPH had no way of knowing how large or small a provider/practice was Orders decreased by 0-82%, depending on vaccine type Learned that this was not the most equitable strategy because some providers over-ordered

Vaccine distribution was divided into phases  Phase 2 (Nov-Dec): Divided into 3 tiers: A, B, C  Strategy: same basic concept for each tier – distribute a certain number of doses based on what a provider ordered rather than cutting by percentages; restrictions lessened as more vaccine became available  Phase 3 (late Dec-Jan): Divided into 4 tiers: A, supplemental, B-C  Strategy: same as Phase 2 By the end of this phase, we were able to provide some vaccine for every provider registered, regardless of provider type All need for p-free doses and LAIV was met Demand for Multidose vials and Pediatric formulations always outweighed supply A blast from the past: Lessons learned about H1N1 Vaccine Distribution

Some things we had control over…  # doses of vaccine going to a specific office  Vaccination, testing, and treatment recommendations being communicated to providers Some things we had no control over at all…  # doses ordered by each provider – did they under-order, over- order?  When the vaccine would arrive  The amount of vaccine coming into San Francisco  The potency recalls/short-dating of vaccine  Whether or not providers actually followed priority group restriction guidelines  Supplies providers were receiving

Other Lessons Learned from H1N1 Logistics planning for school-based mass clinics proved to be too difficult You don’t have to bring vaccine to the people  If they want it, they will come! Our Mass Prophylaxis Plan works great!  Used for December 22 clinic at Bill Graham Civic Auditorium  Vaccinated over 9,000 people in 9 hours  Most people waited less than 30 minutes!  Most reported that the clinic met or exceeded their expectations  Conducted a shift change during the clinic without closing
