Wenzhou.com Faced with the fierce summer influenza, our city started the influenza vaccination work that only started in the fall of previous years. With the first batch of influenza vaccines in place, the day before yesterday, 20 community health service centers in Lucheng District started vaccination work. Yesterday, the reporter learned from the Lucheng District Center for Disease Control and Prevention that the quadrivalent vaccine specifically targets children aged 6 months to 3 years old will also arrive next month, and the gap in the quadrivalent flu vaccine in the infant and toddler age group will be filled.

Yesterday afternoon, at the vaccination clinic of Lianchi Community Health Service Center in Lucheng District, parents took their children to get influenza vaccination one after another. Under the normalization of epidemic prevention and control, everyone wears masks throughout the process. After showing the code and taking the temperature, they go to the health inquiry area, registration area, and vaccination area in turn according to the guidelines. After the vaccination is completed, they will patiently stay in the observation area for 30 minutes.

It is reported that the influenza vaccines used in our city are inactivated vaccines, divided into adult doses and children doses. There are two types of adult dose influenza vaccines: trivalent and tetravalent, which are vaccinated for people over 3 years old; children's dose influenza vaccines are vaccinated for children under 3 years old, and 2 shots are required, with a 1 month interval between them, both of which are trivalent influenza vaccines.

reporter learned that my country's first "infant dosage form" quadrivalent influenza vaccine specifically targeting children aged 6 months to 3 years old has been approved for marketing. It prevents one more influenza B virus subtype, making up for the gap in insufficient prevention of influenza B in the past. At present, our city has placed an order and is expected to arrive next month. At that time, parents can choose to vaccinate according to their own needs.

Regarding the concerns that citizens have just received the influenza vaccine in the fall and winter of last year, whether it is necessary to receive it this summer, experts from the Municipal Center for Disease Control and Prevention said that the influenza virus is a very active infectious disease virus, and its type changes every year and is prone to mutate. The protective effect of the influenza vaccine is determined based on the epidemic strains of the season. Last year's vaccine may not necessarily have a good resistance to this year's virus. Moreover, the vaccination interval of influenza vaccine is not fixed to one year, as long as the vaccine to prevent the corresponding strain is vaccinated before the next epidemic season. For example, the influenza vaccine received in December last year corresponds to the epidemic season from October 2021 to March of the following year (2022). Then, in August this year (not one natural year after the last influenza vaccination was launched), the influenza vaccine can still be vaccinated as soon as possible.

Regarding the doubts that citizens are puzzled about why they are "infected" after getting the flu vaccine, experts said that the protective effect of any vaccine is less than 100%. Moreover, the protective effect of influenza vaccine is determined by the popular strains of the season. The higher the matching of the components of the influenza vaccine with the strains that were prevalent in that year, the better the effect of the influenza vaccine. If the vaccinated strains and the epidemic strains are not matched, it will lead to insufficient protection after vaccination.

Experts remind citizens that in addition to getting influenza vaccine, maintaining good personal hygiene habits is an important means to prevent respiratory infectious diseases such as influenza, including washing hands frequently, using handkerchiefs or tissues to cover their mouths and noses when sneezing or coughing, and try to avoid touching eyes, nose or mouth.
