Inactivated Influenza Vaccine

Inactivated Influenza Vaccine is a flu vaccine that protects against seasonal influenza viruses. Unlike live vaccines, it contains killed viruses that cannot cause infection but stimulate the body to build immunity. It is typically administered annually, as flu viruses mutate rapidly. This vaccine is especially important for people at higher risk of flu-related complications, such as the elderly, children, and individuals with weakened immune systems or chronic health conditions.

Uses of Inactivated Influenza Vaccine

• Prevention of seasonal influenza (flu)
• Protection for high-risk groups (elderly, immunocompromised)
• Reduces risk of flu-related complications

How Inactivated Influenza Vaccine Works

The vaccine contains inactivated (killed) flu viruses. When administered, the body recognizes these as foreign and produces antibodies, providing immunity against future infections by the active virus strains.
