Quadrivalent Influenza Vaccine (Injection)2024/25

Influenza is a respiratory disease caused by viruses that circulates globally every year. Though the symptoms may vary, they typically include fever, headache, muscle aches, fatigue and coughing. Severe influenza can also lead to hospitalization and even death. To effectively prevent influenza and its complications, getting an influenza vaccine is the best choice.

The quadrivalent influenza vaccine is one of the most advanced flu vaccines available today. It contains four different influenza virus strains:

1. Two A-type influenza viruses (H1N1 and H3N2)
2. Two B-type influenza viruses

By immunizing against these four virus strains, the quadrivalent vaccine can provide you with broader protection and lower the risk of getting the flu.
The quadrivalent vaccine is administered through injection, typically starting in the fall of each year. It is recommended for everyone aged 6 months and above, especially those at high risk.

Recommendations for Quadrivalent Influenza Vaccination

To achieve the best immune protection, it is recommended that you get the latest quadrivalent influenza vaccine every year. The vaccine’s effectiveness usually lasts for one year, as the influenza viruses are constantly mutating, and the vaccine components are adjusted annually based on the latest circulating strains.
The optimal time to get vaccinated is between October and November, so that sufficient antibodies can be built up before the peak flu season arrives. However, if you miss this window, you can still get the vaccine throughout the flu season.

The quadrivalent influenza vaccine is recommended for everyone aged 6 months and above, but it is especially important for certain high-risk groups:

1. Adults aged 65 and older: Older adults have declining immune systems and are more susceptible to influenza and its serious complications, such as pneumonia.
2. Pregnant women: Getting the flu vaccine during pregnancy can protect both the mother and the unborn child.
3. Children aged 6 months to 5 years: Children’s immune systems are not yet fully developed, making them more vulnerable to influenza.
4. People with chronic medical conditions: Those with conditions like heart disease, diabetes, or asthma are at higher risk of worsening their illness if they get the flu.
5. Healthcare workers and caregivers: They are often in close contact with patients and can easily get and transmit the flu virus.

Even if you don’t belong to the high-risk groups, getting the quadrivalent influenza vaccine can still lower your risk of getting the flu and missing work or school. Additionally, you will be contributing to the community’s public health by helping to reduce virus transmission.

Side Effects and Risks of the Quadrivalent Influenza Vaccine

Like any other vaccine, the quadrivalent influenza vaccine may cause some mild side effects, but most people can tolerate them well. Common side effects include:

• Soreness, redness, and swelling at the injection site
• Mild fever
• Muscle aches
• Headache
• Nausea

These side effects usually go away within 24-48 hours and are a normal immune response. If the symptoms persist or worsen, please seek medical attention immediately.

Serious allergic reactions are very rare, but if symptoms like difficulty breathing, facial and throat swelling occur, immediate medical attention and appropriate treatment are required.

Overall, the benefits of the quadrivalent influenza vaccine far outweigh the risks. It can effectively prevent influenza and reduce the incidence of complications, which is crucial for protecting individual and public health.
