Flu season is here in full force.Get protected now. It's not too late to get vaccinated!
Getting vaccinated each year is the best way to protect yourself and your family from seasonal flu. Everyone six months of age and older should get vaccinated against seasonal influenza (flu).
Seasonal influenza (flu)
The flu is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death. Some people, such as older people, young children, pregnant women and people with certain health conditions, are at high risk for serious flu complications.
People who have the flu often feel some or all of these symptoms:
- Fever or having chills
- Sore throat
- Runny or stuffy nose
- Muscle or body aches
- Extreme tiredness
- Some people may have vomiting and diarrhea, though this is more common in children.
Complications of seasonal flu can include bacterial pneumonia, ear infections, sinus infections, dehydration, and worsening of chronic medical conditions, such as congestive heart failure, asthma, or diabetes.
How flu spreads
Flu viruses spread mainly by droplets made when people with flu cough, sneeze or talk and droplets are breathed into the mouths or noses of people who are nearby. A person might also get flu by touching a surface or object that has flu virus on it and then touching their own mouth, eyes or nose.
You may be able to pass on the flu to someone else before you know you are sick, as well as while you are sick. Most healthy adults can infect others beginning 1 day before symptoms start and up to 5-7 days after becoming sick. Some people, especially children and people with weakened immune systems, can infect others for an even longer time.
The best way to prevent the flu is to get vaccinated each fall. All people 6 months of age and older should get flu vaccine. The vaccine is available now in our community.
Some children under 9 years old require 2 doses of influenza vaccine separated by at least 4 weeks to develop an adequate immune response. Influenza vaccine dosing algorithm for children aged 6 months through 8 years can be found here. (PDF)
It takes up to 2 weeks for protection to develop after the shot and protections lasts about a year.
There are two ways to get vaccine
- Flu shot
- Injection that contains dead (inactivated) influenza virus, given by injection into the muscle.
- Some inactivated influenza vaccine contains a preservative called thimerosal. Thimerosal-free influenza vaccine is available. Ask your healthcare provider for more information.
- A "high-dose" inactivated influenza vaccine is available for people 65 years of age and older.
- Flu Vaccine, Inactivated or Recombinant (PDF)
- Nasal spray
- A live weakened virus vaccine that is sprayed into the nose. This vaccine is approved for healthy people 2 - 49 years old and those who are not pregnant.
- Adults and older children need one dose of influenza vaccine each year. Some children younger than 9 years of age need two doses to be protected. Ask your healthcare provder.
