When should the flu vaccine be given?

Every time the seasons change, some elderly people and children always get the flu, and this cold is very serious, often accompanied by coughing and fever. If not treated in time, it may cause other diseases. So many people want to take some defensive measures before the flu comes, among which the flu vaccine is very popular. So when should the flu vaccine be given?

It is generally appropriate to administer the influenza vaccine 1-2 months before the influenza epidemic. Influenza epidemics in my country are mainly concentrated from November each year to around March of the following year, so the influenza vaccination time is generally scheduled from September to November. In areas south of the Yangtze River, the weather gets cold late, so the vaccination time is generally concentrated in October-December. Vaccination in Guangdong can start in September and last until around February of the following year.

Although the best time to get a flu shot is before a flu epidemic, people can still get a flu shot to get protection during a flu epidemic. According to Aventis Pasteur, the influenza vaccine will trigger the body to produce antibody protection about 10-15 days after vaccination, so there is no problem even if the influenza vaccine is received in November or December. People can plan the vaccination time in advance according to their actual situation, and there is no need to "crowd together" for vaccination.

It should be noted that it is best to vaccinate infants and young children aged 6 months to 3 years old with influenza vaccine in advance, and it should be a child-specific vaccine. Infants and young children need two flu shots to provide optimal protection, with a month between the two doses, so parents need to plan ahead. In addition, infants and young children aged 6 months to 3 years are the key groups for the national immunization program and need to receive multiple immunization vaccines every year. Therefore, the dosage of influenza vaccine for infants and young children is different from that for older children, and only 0.25 ml can be administered each time.

The above is some detailed introduction about when to get the flu vaccine. Generally speaking, the time for vaccination is different in different regions. You can go to the local epidemic prevention station for consultation. Another thing to note is that not everyone can get the flu vaccine. If you have already experienced physiological phenomena, you cannot get the flu vaccine.
