Vaccine Information
9/15--FDA approved four vaccines against 2009 H1N1 flu virus (made by CSL Limited, MedImmune LLC, Novartis Vaccines and Diagnostics Limited, and sanofi pasteur Inc.)
H1N1 vaccine manufactured using same processes as seasonal flu vaccine, under same FDA manufacturing oversight, product quality testing and lot release procedures.
Seasonal and H1N1 flu vaccines both produced in formulations with and without thimerosal, a mercury-containing preservative.
Potential side effects of H1N1 vaccine similar to seasonal flu vaccines. For injected, soreness at injection site most common. Others may include mild fever, body aches, fatigue. For nasal spray, runny nose, nasal congestion most common for all ages; sore throats in adults, and fever in kids 2-6 years old.
SD to receive about 110,000 doses by mid-October, 48,000 doses weekly thereafter
Initial doses targeted to groups at highest risk for H1N1
o Pregnant women
o People who live with or care for infants younger than 6 months
o Children 6 months to 4 years
o Children 5-18 years with chronic health conditions
o Health care and emergency medical services workers (hospitals manage distribution of vaccine to health care workers; ambulance services for EMS)
As more vaccine available, it will be administered beyond priority groups
Federal govt will purchase vaccine, supplies to administer it and distribute to states
Vaccination is voluntary
Vaccine is free but some providers may charge an administration fee
Seasonal flu vaccine should be given as soon as available to appropriate target groups; SD reported 525 hospitalizations for seasonal flu last year and 4 deaths
