Fluarix Tetra 2020/2021 NH Vaccine is designed to safeguard individuals against influenza, commonly known as the flu. By introducing a small dose of deactivated flu virus into the body, the vaccine triggers the immune system to build protection against the disease. It's essential to note that this vaccine does not cure an existing flu infection; rather, it is a preventive measure.

This vaccine is administered via injection into a muscle by a healthcare professional, usually recommended as the cold season approaches and the flu virus becomes prevalent. Typically, a single injection is adequate to provide protection for a whole year. Renewing the vaccination annually is advised due to the frequent emergence of new strains of the flu virus, prompting the development of different vaccines. The vaccine is primarily targeted towards individuals aged 18 and above, with particular emphasis on older adults and those with chronic health conditions like diabetes, heart failure, kidney failure, or COPD.

While Fluarix Tetra 2020/2021 NH Vaccine may result in minor side effects, the benefits of vaccination significantly outweigh the risks associated with contracting the flu. Influenza is a severe illness responsible for numerous fatalities annually. Common side effects of the vaccine include headache, weakness, fatigue, and localized pain or swelling at the injection site, which are typically temporary. Should any side effects persist or cause concern, consulting a healthcare provider is recommended.

Prior to receiving the vaccine, it is crucial to inform your doctor of any ongoing illness with a high fever or any history of allergic reactions to vaccines. Certain medications may interact with the flu vaccine, necessitating a discussion with your healthcare provider regarding other prescribed drugs. While the vaccine may not offer complete protection to everyone, it can mitigate the severity of flu symptoms if an infection occurs. It's important to note that the vaccine does not guard against avian flu or the common cold. Pregnant or breastfeeding individuals should seek medical advice before getting vaccinated.
