FluLaval Quadrivalent is a seasonal influenza vaccine designed to protect against four different strains of the flu virus. It includes two influenza A strains and two influenza B strains, offering broader protection than traditional trivalent vaccines, which only cover three. This quadrivalent formulation is updated each year to match the strains expected to circulate during the upcoming flu season. FluLaval is suitable for use in individuals aged six months and older and is typically administered as a single dose through an intramuscular injection. It is preservative-free, which makes it a preferred option for people with concerns about additives like thimerosal. The goal of the vaccine is to reduce the risk of flu infection, prevent serious complications, and reduce the spread of the virus in the community.
Given as a once-per-season injection.
FluLaval Quadrivalent is given by a healthcare professional using a sterile technique. For adults and older children, the injection is usually given in the upper arm (deltoid muscle). For infants and toddlers, the anterolateral thigh is preferred. The vaccine must be stored in a refrigerator and not frozen. Before administering, the solution should be checked to ensure it’s clear and particle-free. After the shot, patients are often monitored for 10–15 minutes to ensure no immediate allergic reaction occurs.
FluLaval Quadrivalent works by helping your body build immunity against the influenza virus. It contains inactivated (killed) flu virus particles that cannot cause illness but still trigger the immune system to produce antibodies. These antibodies remain in your system and are ready to fight off real influenza viruses if you’re exposed later in the season. The vaccine’s quadrivalent nature provides protection against more strains, making it more effective in reducing the chances of catching the flu or experiencing complications from it.
Most people tolerate FluLaval Quadrivalent well, with only mild side effects. Common symptoms include pain, redness, or swelling at the injection site. Some may experience fatigue, headache, low-grade fever, or muscle aches for a day or two. These side effects usually go away on their own. In rare cases, more serious reactions like allergic responses may occur, including difficulty breathing or swelling of the face and throat. Anyone experiencing severe symptoms should seek immediate medical attention.
Most side effects are short-lived and manageable.
Before getting the vaccine, it’s important to tell your healthcare provider about any allergies, especially to eggs, since the vaccine is produced using egg-based technology. While most people with egg allergies can safely receive it, caution is still advised. People who have experienced severe allergic reactions to previous flu shots should not receive this vaccine. It’s also best to wait if you’re currently experiencing moderate to severe illness. Pregnant and breastfeeding women should consult their doctor, though flu vaccination is generally recommended. Those with bleeding disorders should inform their provider, as intramuscular injections may increase the risk of bruising.
Use caution if you have a bleeding disorder or take blood thinners.
The vaccine can be given at the same time as other vaccines but should be administered in separate limbs. While it’s generally safe, its effectiveness may be slightly reduced if you’re taking immunosuppressive medications. Patients on blood thinners should be cautious due to the potential for injection site bruising.
The dosage for FluLaval Quadrivalent depends on the individual’s age and vaccination history. Children aged six months through eight years receiving the vaccine for the first time usually need two 0.5 mL doses, spaced four weeks apart. All others, including those aged nine and older, require just one 0.5 mL dose per flu season. It is recommended to get vaccinated early in the flu season, typically in the fall, before the virus begins to spread widely. The vaccine should be kept cold but not frozen to maintain its effectiveness.
Do not use expired or frozen vaccine.
FluLaval Quadrivalent is not available over the counter and requires a prescription. It must be administered by a trained healthcare provider who can evaluate whether the vaccine is appropriate based on your health history. Vaccination records are maintained for monitoring and safety. In some countries or states, standing orders may allow pharmacists or nurses to provide the vaccine without a direct individual prescription, but still under medical supervision.
Medical supervision ensures safe use.
