Winter is a time of high incidence of respiratory diseases such as influenza
Has your child been vaccinated against the flu?
Hot-button issues of childhood vaccination
The experts will answer them one by one
Influenza vaccination is one of the most economical and effective prevention and control measures to prevent influenza and reduce the burden of influenza disease, mainly for the prevention of influenza A and B. Influenza vaccination can reduce the risk of influenza in children, reduce the severity of flu symptoms, and reduce the probability of serious complications. After vaccination, the body's immune system is stimulated to produce protective antibodies against the influenza vaccine, and when the human body is infected with the influenza virus, the protective antibodies will play a role against the influenza virus.
It is important to note that the protection period of the flu vaccine is generally not more than one year, and the virus strain of the flu is not necessarily the same every year, so it is best to get the flu vaccine every year.
Vaccination is not recommended in the acute phase of respiratory infections. Minor discomforts such as a cold or cough usually do not affect the effectiveness of vaccination, but it may cause some adverse reactions or coincidence after vaccination, and it is recommended to consider vaccination after the respiratory tract infection in children has been completely cured.
You can get vaccinated 1~2 weeks after the respiratory infection has recovered. Vaccines that are postponed due to various reasons are generally vaccinated and revaccinated in accordance with the procedures in the "Immunization Program Vaccine Childhood Immunization Program" or the procedures in the instructions of various non-immunization program vaccines, and the standardized completion of supplementary vaccination generally does not affect the vaccination effect.
Fever after vaccination is usually only febrile and rarely accompanied by other respiratory symptoms such as cough, fatigue, chest tightness, shortness of breath, and sore throat. Fever after vaccination usually appears within 1~2 days after vaccination, mostly below 37.5 °C, only a few may cause high fever of about 38.5 °C, and the duration is generally not more than 3 days.
Influenza fever usually appears 1~2 weeks after infection with the virus, and lasts for a long time, usually accompanied by other symptoms, such as chills, muscle aches, sore throat, etc., and lasts for about a week.
