Recently, it is the best time to get influenza vaccination. Many parents will take their children to get influenza vaccination to prevent infection with influenza . There are many rumors about influenza vaccines among the people, such as: Will children suffer from autism after being vaccinated? Will influenza vaccine affect children's own immunity? wait. Do you all believe it completely? The following summarizes several misunderstandings about young children's vaccines and explains them one by one.
Misunderstanding 1: Influenza B vaccine is more comprehensive than influenza A vaccine?
There is no vaccine for influenza B alone on the market, mainly trivalent and quadrivalent influenza vaccines. Both vaccines already include influenza A. Another type is a vaccine to prevent Haemophilus influenzae type B . Haemophilus influenzae type B is a bacteria that can cause severe invasive infection, especially affecting children. Invasive infections are the most common symptoms of meningitis, and bacteria often appear at the same time when entering blood. In contrast to its name, Haemophilus influenzae B does not cause influenza, and it has nothing to do with influenza virus , but the name is more likely to cause confusion.
Misunderstanding 2: The components of the vaccine are basically strongly toxic?
vaccine can be mainly divided into two categories: active anti-toxic vaccine and inactivated vaccine . The former is prepared using non-toxic or weak virulent strains, while the latter is an artificial method such as heating to eliminate pathogens but retain their key structure that can cause the human immune reaction. Vaccines can only be launched on the market after they have been proven safe and effective through large-scale clinical trials.
Misconception 3: Vaccination reduces children's autoimmunity?
vaccination, the immune system will produce antibodies against related diseases, and the appearance of the bacteria is recorded in the immune system. When the same pathogen is encountered again, the immune system will produce a large number of antibodies to organize effective defenses. Vaccination is one of the most effective ways to prevent and mitigate infectious diseases today.
Misunderstanding 4: Can the traditional three-in-one vaccine be injected with Japanese encephalitis vaccine cause autism?
Traditional three-in-one vaccine is a vaccine that synthesizes three vaccines into one dose and gets one shot at the same time to prevent three infectious diseases. The vaccine contains diphtheria and tetanus toxoids and pertussis vaccines made after whole-cell killing, and although there is a chance of side effects, it is mostly quite mild. So far, there is no evidence that the simultaneous injection of this vaccine and a new generation of three-in-one vaccines will affect infant intelligence development and other issues.
Misconception 5: Is the most effective way to prevent influenza?
For prevention, the most effective and direct way is to take personal protection. Avoid going to crowded and closed environments during the epidemic of infectious A; especially avoid contact with respiratory patients with flu symptoms (such as fever, cough, runny nose) or pneumonia. Keep the room ventilated and breathable at normal times, and eat more foods such as vegetables and fruits that are high in vitamins. Cover your mouth and nose with a tissue when coughing or sneezing, and throw the tissue into the trash can. Wash your hands frequently and thoroughly with soap and water, especially after coughing or sneezing.
