Seasonal Flu Vaccine Supply • June 2009 vaccine manufacturers state 118 million doses of seasonal flu vaccine will be produced • August 2009 numbers revised to 114 million doses produced • Represents ~3% reduction from original projection • Amount of vaccine distributed similar to 2008-2009 flu season
U.S. Seasonal Influenza Vaccine: Production and Use *Amount reported by manufacturers to CDC which is being validated.
Vaccine Supply Challenges • Vaccine available much earlier • Increased demand • Facilities switched to production of H1N1 vaccine production • Delay in availability of vaccine • Pre-booked orders canceled or reduced
Long-Term Care Facilities (LTCF) Affected • Reports of vaccine shortages among LTCFs • Orders canceled or reduced • Additional 500,000 doses made available for LTCF in December • Pharmacies, supermarkets, community vaccinators provided vaccine
Demand Remains High • Cumulative seasonal influenza vaccination coverage since August was 42% by Jan 2 • Demand for seasonal vaccine remains higher than supply (139-173 million vs. 114 available) • Majority of people report they have gotten, will definitely get, or will probably get seasonal flu vaccine (58%)
Outlook for Next Season • ACIP Influenza Work Group considering universal flu recommendation • Begin 2010-2011 • Two stage • Encourage for 2010-2011 • Full implementation 2011-2012 • Fluzone High Dose Vaccine • High-dose seasonal flu vaccine for persons ≥65 years • Contains 4 x amount of antigen • FDA licensed December
Outlook for Next Season (2) • Preliminary reports indicate manufacturers plan to make at least as much vaccine as this year • Will this be enough? • Vaccine composition • Strains will be identified at VRBPAC* meeting in February • Likely include 2009 H1N1 strain *Vaccines and Related Biological Products Advisory Committee
