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
A blast from the past: Lessons learned about H1N1
Vaccine Distribution
 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, overorder?
 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

Who needs 2 doses for 2010-2011?
 For children less than age 9 never immunized against influenza before
2009-10:
 If your practice has kids <9 years who did not get H1N1 vaccine, but who got 2
doses of seasonal in 2009-2010 or at least 1 dose in an earlier season, but none
in 09-10, you can give them 1 dose of H1N1 now, then they will only 1 dose
during the 2010-2011 season.
