Vaccination Guide — H1N1 (Swine Flu)
What is it?
Swine flu is a respiratory infection caused by influenza A viruses. The outbreak of what is popularly called swine flu involves a new H1N1 type A influenza strain that's a genetic combination of swine, avian and human influenza viruses. It can be spread from human to human.
Symptoms
Symptoms are similar to other flu strains (fever, cough, sore throat, heachache, chills, diarrhea, vomiting, fatique) and will develop three to five days after exposure. The illness will continue for approximately eight days.
Complications and risk factors
H1N1 influenza complications include worsening of chronic conditions like heart disease, asthma, and diabetes. Pneumonia and respiratory failure may occur in untreated cases.
2009 vaccination recommendations
A H1N1 vaccine is currently in development and expected to be available in Oct. 2009. The H1N1 vaccine is not intended to replace the seasonal flu vaccine; it is intended to be used alongside the easonal flu vaccine.
The CDC will be distributing the 2009 H1N1 influenza vaccine to each state. It is anticipated that two doses of the vaccine will be needed to induce immunity.
The following groups have been identified as the first target populations for the vaccination when available:
- pregnant women
- people who live with or care for children younger than 6 months of age
- healthcare and emergency medical services personnel
- persons between the ages of 6 months and 24 years old
- people ages of 25 through 64 years of age who are at higher risk for 2009 H1N1 because of chronic health disorders or compromised immune systems.
Once the demand for vaccine for these groups has been met, the next group to be vaccinated includes everyone from the ages of 25 through 64 years. Unlike seasonal flu, people 65 or older appear to be less at risk of infection with the 2009 H1N1 virus than younger people. However, once vaccine demand among younger age groups has been met, programs and providers should offer vaccination to people 65 or older.
