Not just children and the elderly... People like this should definitely get the flu vaccine in October and November.

High-risk groups for the flu must receive the flu vaccine in the fall. The flu is an acute febrile respiratory illness caused by influenza virus infection, primarily presenting symptoms such as high fever, cough, and body aches.

To properly see the effectiveness of the flu vaccine, it is best to get vaccinated in November or October, a month before the flu season begins in late November. It takes about a month after vaccination for the body to produce enough antibodies to protect against external substances. These antibodies then fight against the influenza virus when it enters the body, helping to prevent illness. This immune response typically lasts for about six months.

Elderly individuals aged 65 and over, infants and young children, and other high-risk groups are at greater risk of developing complications such as pneumonia or otitis media if they contract the flu, and in severe cases, it can lead to death. Therefore, it is essential for ▲children aged 6 to 59 months ▲elderly individuals aged 65 and over ▲people with chronic illnesses ▲pregnant women to receive the vaccination. Many pregnant women refuse vaccination due to concerns about medication, but pregnant women have weakened immune systems and are at higher risk of contracting the flu, so vaccination is absolutely necessary. The World Health Organization (WHO) designates pregnant women as a top priority for flu vaccination and recommends that they receive the vaccine regardless of the stage of pregnancy.

Influenza viruses change their characteristics every year, so you need to get a new preventive vaccine each year to build immunity against them.
