Are There Different Types of Flu Shots Available?
Yes, there are several types of Flu Shots available to meet different age groups, health needs, and risk profiles. The most common is the standard-dose quadrivalent vaccine, which protects against four strains of influenza - two A strains and two B strains. High-dose and adjuvanted versions are available for adults aged 65 and older to improve immune response, as older adults tend to have weaker immune systems. There’s also a cell-based version and a recombinant version, both of which are produced without the use of eggs and may be better for individuals with specific allergies or sensitivities.
In addition to injectable flu shots, there’s a nasal spray version known as the live attenuated influenza vaccine (LAIV). However, this is only approved for healthy individuals aged 2 to 49 and is not recommended for pregnant individuals, immunocompromised persons, or those with certain chronic medical conditions. Your healthcare provider will consider factors such as your age, medical history, allergy profile, and previous vaccine responses to recommend the most appropriate and effective type of flu vaccine for your individual needs.
