Influenza (Flu) Vaccine: What Everyone Should Know
Who Should Get Flu Vaccine?
Flu vaccination is recommended for everyone aged 6 months and older, including pregnant women and individuals with certain medical conditions.
It's especially crucial for individuals at high risk of complications from the flu, such as older adults and those with chronic health conditions.
CDC recommends annual flu vaccination for everyone aged 6 months and older.
-
The flu shot is updated annually to match the circulating flu strains, ensuring optimal protection against the virus.
-
Vaccination is particularly important to reduce the risk of flu-related complications, hospitalizations, and deaths.
Who Should Not Get Influenza (Flu) Vaccine?
Tell your doctor about any severe allergies. Some people should not get some Influenza (Flu) vaccines if:
-
Severe Allergies: Those who have had a life-threatening allergic reaction (anaphylaxis) to any ingredient in the flu vaccine or to a previous dose of the flu vaccine should not receive it.
-
Allergy to Vaccine Components: Individuals with an allergy to any component of the flu vaccine should avoid getting vaccinated.
-
Egg Allergy: Historically, people with severe egg allergies were advised against flu vaccination due to the use of egg proteins in some flu vaccines. However, most flu vaccines nowadays contain very little or no egg protein and are considered safe for individuals with egg allergies. Still, it's essential to consult a healthcare provider if you have concerns about egg allergies before getting vaccinated.
-
History of Guillain-Barré Syndrome (GBS): Individuals who have had Guillain-Barré Syndrome within six weeks of a previous flu vaccination should consult their healthcare provider before getting vaccinated again.
-
Current Illness: People who are currently ill with a fever should wait until they recover before getting vaccinated.
What Types of Flu Vaccines Are There?
There are several types of flu vaccines available, including:
- Inactivated influenza vaccine (IIV)
- Recombinant influenza vaccine (RIV)
- Live attenuated influenza vaccine (LAIV)
Your healthcare provider can help determine the most suitable flu vaccine for you based on your age, health status, and preferences
Getting vaccinated against influenza, commonly known as the flu, offers several benefits:
-
Prevention of Illness: The flu vaccine is designed to protect against the strains of influenza virus predicted to be most common during the flu season. By receiving the vaccine, you lower your risk of getting sick with the flu or experiencing severe symptoms if you do contract the virus.
-
Reduced Severity of Symptoms: Even if you do get the flu after being vaccinated, studies have shown that vaccinated individuals are less likely to experience severe symptoms, complications, or require hospitalization compared to those who are unvaccinated.
-
Protection for Vulnerable Populations: Vaccination helps protect vulnerable populations, including young children, the elderly, pregnant women, and individuals with chronic health conditions, who are at higher risk of experiencing severe complications from the flu.
-
Prevention of Spread: By reducing the likelihood of getting sick with the flu, vaccination also helps prevent the spread of the virus to others, including family members, coworkers, and the broader community. This is particularly important for individuals who may have weakened immune systems and cannot receive the vaccine themselves.
-
Reduction in Healthcare Costs: Flu vaccination can lead to significant cost savings by preventing illness, hospitalizations, and medical visits associated with flu-related complications. It also helps reduce the burden on healthcare systems, especially during peak flu seasons.
-
Contribution to Herd Immunity: When a large portion of the population is vaccinated against the flu, it creates herd immunity, which provides indirect protection to those who cannot be vaccinated or have weaker immune responses. This is crucial for protecting the most vulnerable members of society.
-
Annual Protection: The influenza virus undergoes frequent changes, requiring the flu vaccine to be updated annually to match the circulating strains. By getting vaccinated each year, you ensure that you have current protection against the most prevalent strains of the virus.

How Effective Are These Vaccines?
Flu vaccination is the best way to prevent the flu and its complications. While the effectiveness of the flu vaccine can vary from season to season, studies have shown that vaccination significantly reduces the risk of flu illness, hospitalizations, and deaths.
Common side effects of flu vaccination may include soreness at the injection site, low-grade fever, and mild body aches. Serious side effects are rare.

What Are the Possible Side Effects?
Like any medication, vaccines can have side effects, although most people who receive vaccines experience no adverse effects. Some individuals may report mild side effects such as a sore arm at the injection site.
The most common side effects of Flu vaccines are usually mild and may include:
-
Soreness, Redness, or Swelling at the Injection Site: This is the most common side effect and usually occurs within hours or days after receiving the vaccine. It typically resolves on its own without treatment.
-
Low-Grade Fever: Some people may experience a mild fever as a response to the vaccine, usually within 24 hours of vaccination. Fever reducers such as acetaminophen or ibuprofen can help alleviate discomfort if needed.
-
Muscle Aches or Fatigue: You may experience mild muscle aches or fatigue, similar to symptoms of a mild cold, as your body's immune system responds to the vaccine. These symptoms typically resolve within a few days.
-
Headache: Headaches are another common side effect of flu vaccination and usually resolve on their own without treatment. Drinking plenty of fluids and getting adequate rest can help alleviate symptoms.
-
Nausea or Loss of Appetite: Some individuals may experience temporary nausea or loss of appetite after receiving the flu vaccine, although these symptoms are less common.
-
Allergic Reactions: Serious allergic reactions to flu vaccines are rare but can occur. Signs of a severe allergic reaction may include difficulty breathing, swelling of the face or throat, rapid heartbeat, or dizziness. If you experience any of these symptoms after receiving the vaccine, seek medical attention immediately.
To prevent fainting and related injuries, adolescents should remain seated or lying down during vaccination and for 15 minutes after receiving the injection.
