Flu shots are recommended for most people, but certain groups are particularly encouraged to get vaccinated because they are at higher risk for complications from the flu. Here’s a breakdown of who should definitely consider getting a flu shot:

### 1. **Everyone Aged 6 Months and Older**
   - The **CDC** recommends annual flu vaccination for **everyone** aged 6 months and older, with **rare exceptions**.
   
### 2. **High-Risk Groups**
   People at higher risk of serious flu-related complications should definitely get vaccinated. These groups include:
   
   - **Pregnant women**
     - The flu shot protects both the mother and the baby (who can't get a flu shot until 6 months old).
   - **Young children** (especially those under 5, and particularly under 2).
   - **People 65 years and older**
     - Older adults are more likely to experience severe illness, hospitalizations, or death from flu complications.
   - **People with chronic health conditions** such as:
     - Asthma
     - Heart disease
     - Diabetes
     - Chronic lung disease (e.g., COPD)
     - Kidney disease
     - Liver disease
     - Immunocompromised individuals (e.g., those undergoing cancer treatment, HIV-positive, etc.)
   
### 3. **Healthcare Workers and Caregivers**
   - People who work in healthcare settings or care for others at high risk of complications should get vaccinated to avoid spreading the flu.
   
### 4. **Residents of Long-Term Care Facilities**
   - Nursing home residents or people in assisted living are highly vulnerable to severe flu complications.

### 5. **Individuals Living with or Caring for High-Risk Persons**
   - Family members or caregivers of infants, the elderly, or those with weakened immune systems should get vaccinated to protect them.

### Who Should **Not** Get a Flu Shot:
   - **Infants younger than 6 months** (too young to receive the vaccine).
   - **People with severe, life-threatening allergies** to the flu vaccine or any of its ingredients (like gelatin or antibiotics in the vaccine).
   - **People with a history of Guillain-Barré Syndrome** should consult their doctor before getting vaccinated.
   - If you’re **sick with a fever**, wait until you’ve recovered before getting the shot.

Overall, getting a flu shot helps protect both you and those around you, reducing the spread of influenza in your community.
