Seasonal influenza vaccines are designed to protect against the influenza viruses that research indicates will be most common during the upcoming season. These vaccines are updated annually to provide optimal protection against the circulating strains of the influenza virus. Influenza vaccines are typically administered before the start of the flu season, which varies by region but generally occurs in the fall and winter months.

Types of Influenza Vaccines

Influenza vaccines are available in several forms, including inactivated vaccines, live attenuated vaccines, and recombinant vaccines. Each type has specific characteristics and is suitable for different populations.

Inactivated Influenza Vaccines

Inactivated influenza vaccines (IIV) contain virus particles that have been killed and are incapable of causing disease. These vaccines are administered via injection and are suitable for a wide range of age groups, including children, adults, and the elderly.

Live Attenuated Influenza Vaccines

Live attenuated influenza vaccines (LAIV) contain live virus particles that have been weakened so they cannot cause illness in healthy individuals. These vaccines are typically administered as a nasal spray and are recommended for healthy, non-pregnant individuals aged 2 through 49 years.

Recombinant Influenza Vaccines

Recombinant influenza vaccines (RIV) are produced using recombinant DNA technology. These vaccines do not require the use of the influenza virus or eggs in their production, making them suitable for individuals with egg allergies.

Commonly Used Influenza Vaccines

Several influenza vaccines are commonly used worldwide. These vaccines are formulated to protect against the most prevalent strains of the influenza virus each year.

Fluzone

Fluzone is a widely used inactivated influenza vaccine. It is available in various formulations, including high-dose versions for older adults who may have a weaker immune response. Fluzone is administered via injection and is suitable for individuals aged 6 months and older.

FluMist

FluMist is a live attenuated influenza vaccine administered as a nasal spray. It is suitable for healthy individuals aged 2 through 49 years. FluMist is not recommended for pregnant women or individuals with certain medical conditions.

Fluad

Fluad is an adjuvanted inactivated influenza vaccine designed to enhance the immune response in older adults. It is specifically formulated for individuals aged 65 years and older.

Flublok

Flublok is a recombinant influenza vaccine that does not use eggs in its production. It is suitable for individuals aged 18 years and older, including those with egg allergies.

Vaccination Recommendations

Annual influenza vaccination is recommended for most individuals aged 6 months and older, with few exceptions. Vaccination is particularly important for individuals at higher risk of complications from influenza, including young children, older adults, pregnant women, and individuals with certain chronic health conditions.
