Vaccine Information – H1N1
• Effective Monday, November 9, H1N1 vaccine will be available to Tier 2 risk groups – kids from
5-18 years, young adults 19-24, adults 25-64 with chronic health conditions.
• DOH has received/distributed more than 76,000 total doses to 400+ locations across SD; not all in
Tier 1 have been vaccinated but more public clinics scheduled every week – important to start
reaching out to next group of individuals at high risk.
• Scheduled public clinics now open to all high risk; private providers to offer vaccine to all high risk
as well. Che for updated listing of scheduled clinics.
High Risk Individuals Eligible for H1N1 Vaccine
• Pregnant women

neuromuscular diseases, renal disease, cardiovascular disease)
• DOH shipping H1N1 vaccine as soon as it arrives; expectation that providers in turn administer
those doses as quickly as possible to all high risk groups. H1N1 doses should be entered into the
SD Immunization Information System within 48 hours of administration – necessary to track
coverage in high risk populations and determine when vaccine can be offered beyond risk
groups.
