Acute illness (e.g., flu, infections)

Acute illnesses, like the flu and other infections, can affect anyone and often come on quickly. The flu, for example, is a contagious respiratory illness caused by influenza viruses. Symptoms may include fever, body aches, fatigue, cough, sore throat, and chills. While many people recover on their own, these illnesses can sometimes lead to serious complications, especially for young children, older adults, and people with certain health conditions.

Prevention through vaccination is one of the best ways to protect yourself and those around you. The yearly flu shot helps your immune system build protection against the virus and lowers the risk of severe illness. The Centers for Disease Control and Prevention (CDC) recommends that everyone aged six months and older, with few exceptions, receive a flu shot each year. Protection from the vaccine generally lasts through flu season, but annual vaccination is essential to maintain immunity.

What is the flu?
The flu, or influenza, is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness and, in some cases, can lead to hospitalization or even death.

How is the flu different from a cold?
Both the flu and the common cold are respiratory illnesses, but flu symptoms tend to be more severe and can lead to serious complications. Flu symptoms often come on suddenly and may include fever, body aches, fatigue, and cough.

What is a flu shot?
A flu shot is a vaccine designed to protect against influenza viruses. It contains inactivated or weakened viruses that help your body build antibodies to defend against infection.

Who should get a flu shot?
The CDC recommends that everyone aged six months and older get a flu shot each year. This is especially important for people at higher risk of complications, including young children, pregnant women, older adults, and those with certain health conditions.

When is the best time to get a flu shot?
The best time is in early fall, before flu season begins. However, vaccination later in the season is still beneficial.

Can the flu shot give you the flu?
No. The vaccine contains inactivated or weakened viruses that cannot cause influenza. Some people may experience mild side effects like soreness, low-grade fever, or fatigue.

Is it okay to get a flu shot if you have the flu?
No. The flu shot prevents infection but does not treat it. Wait until you have recovered before getting vaccinated.

How effective is the flu vaccine?
Effectiveness varies yearly based on how well the vaccine matches circulating flu viruses. Even in years with lower effectiveness, the vaccine still provides significant protection against severe illness.

What are the common symptoms of the flu?
Fever, cough, sore throat, body aches, fatigue, headaches, and chills. Children may also experience nausea, vomiting, and diarrhea.

How long does flu shot protection last?
Protection typically lasts through the flu season, but immunity can wane, so annual vaccination is important.

What are the side effects of the flu vaccine?
Most people experience mild side effects, such as a sore arm, low-grade fever, headache, or fatigue. Severe reactions are rare. Consult your provider if you have allergies to vaccine components or experience unusual symptoms.

How long does it take for the flu shot to become effective?
It takes about two weeks for your body to build protection after vaccination. Early vaccination ensures coverage before flu activity peaks.

Why is the flu shot important during COVID-19 and other respiratory illness outbreaks?
Getting the flu shot helps reduce overall illness, eases strain on healthcare systems, and strengthens your immune system, which helps protect against serious illness and complications from multiple infections, including COVID-19.
