Introduction
The influenza vaccine generally refers to the vaccine for seasonal influenza. The number of doses required depends on the patient's age. For individuals between 6 months and 3 years of age, two doses are usually needed, while those aged 3 years and older, including adults, typically require one dose. It is recommended to receive the vaccine before the flu season; however, attention should also be paid to precautions before and after vaccination to ensure its safety and effectiveness.
Influenza vaccine generally refers to the vaccine against influenza. The number of doses required for influenza vaccination depends on the patient's age. If the patient is between 6 months and 3 years old, two doses are usually needed. For children aged 3 years and older or adults, only one dose is required. Specific details are as follows:
1. Two-dose regimen
The influenza vaccine is primarily intended for susceptible individuals aged six months and above to prevent infection by the influenza virus. Infants between 6 months and 3 years of age typically have weaker immune systems, thus requiring two doses of the vaccine.
2. One-dose regimen
Children aged 3 years and older, as well as adults, require only one dose of the influenza vaccine. However, annual revaccination is necessary each year to maintain protection. The influenza vaccine is an inactivated vaccine, primarily used to prevent influenza caused by influenza A and B viruses.
For individuals receiving the influenza vaccine for the first time, it is recommended to get vaccinated before the influenza season begins. It is also important to follow pre- and post-vaccination precautions to ensure safety and effectiveness, allowing immunity to be established prior to the peak influenza season. Individuals with special health conditions or those advised by their physicians may require multiple doses. For specific recommendations on dosage and timing, please consult a healthcare provider.
