Flu and People with Asthma

Date: 10/24/24

While seasonal influenza (flu) viruses are detected year-round in the United States, they usually happen during the fall and winter seasons. These viruses often begin to increase in October. People with asthma are at higher risk of getting serious flu issues. This can happen even if their asthma is mild or their symptoms are well controlled by medication. Flu can bring on asthma attacks and can make symptoms worse. This could lead to pneumonia and other acute respiratory diseases.

Importance of Flu Vaccination

Flu vaccinations (or flu shots) are important for people with asthma because they are at a higher risk of getting severe flu complications. Annual flu vaccination is needed to make sure the best possible protection against flu since its effectiveness decreases over time. Protection from flu shot sets in after about two weeks after getting vaccination. The Centers for Disease Control and Prevention (CDC) recommends that everyone six months and older get a flu vaccine annually. The best time is usually around the end of October.

Flu Vaccines for People with Asthma

Most injectable flu shots are approved for use in people six months and older, regardless of whether they have asthma or other health conditions. People with asthma should not receive the nasal spray flu vaccine. Talk to your healthcare provider before getting the nasal spray vaccine.

Other Actions to Protect People with Asthma

In addition to getting a flu shot, people with asthma should take the same actions the CDC recommends for protection. This includes avoiding people who are sick, covering coughs, and washing hands often. People with asthma should always:

  • Take asthma medication as prescribed.
  • Plan and make sure there is at least a two-week supply of any regular medications.
  • Use an asthma action plan.

Anyone having emergency warning signs of flu sickness, including people with asthma, should seek medical attention immediately.
