The role of rotavirus vaccine is to prevent rotavirus infection and diarrhea in autumn. Before ordering food, domestic vaccines are generally sweet oral liquid, which is convenient for children to take without injections. Antibodies are generally produced within 2 weeks after administration, and the antibody concentration reaches the peak within 4 weeks, and the protection rate of severe diarrhea is over 90%. At present, there is no specific treatment for gastroenteritis caused by rotavirus infection Only symptomatic treatment can relieve symptoms, so oral rotavirus vaccine is the most economical and effective way to prevent the disease. After oral rotavirus live vaccine, the protection period is generally one year, and the longest is no more than one and a half years. In other words, in order to avoid diarrhea in autumn, it is best to vaccinate once a year.

Before this, no serious side effects of rotavirus vaccine have been found. However, severe allergic reactions can occur in any vaccination, although it is extremely rare. If your baby is sick, has a fever, has an acute infectious disease or a serious disease, and is allergic or has gastrointestinal injury, then you need to be very careful to postpone the rotavirus vaccination or not vaccinate your baby. If babies feel a little sick, most of them can be vaccinated. But if the baby's condition is moderate or very serious, please wait a moment. No matter what disease your child has, be sure to tell your doctor that your child is ill before you get vaccinated.

Prevent rotavirus diarrhea and develop good hygiene habits, such as washing hands with soap before meals and after defecation, cleaning and boiling bottles and utensils, and then using them. Pay attention to the hygiene of drinking water instead of raw water. Wash fruits and melons when eating them raw, and use a fly cover to prevent flies and cockroaches from biting and crawling food.

Pay attention to the cold. The high incidence of the disease is in autumn and winter, which shows that patients with cold, especially those with abdominal cold, will cause high incidence of the disease. Under normal circumstances, bacteria and viruses in the human body are in balance. However, due to the change of body temperature, the normal balance is broken. Some bacteria and viruses are suppressed, and some bacteria and viruses are developed. Rotavirus is a virus produced when human body temperature drops. Therefore, the main way to prevent this disease is to prevent abdominal cold.

Vaccinate. Rotavirus vaccine is an effective measure to prevent autumn diarrhea. Although rotavirus does not mutate continuously like influenza virus, the immune time of human body is relatively short, so the vaccine needs to be injected once a year to one and a half years, and the protection rate is 75% to 80%. Parents can vaccinate autumn diarrhea vaccine at any time every year according to the planned immunization interval, and produce anti-rotavirus antibodies two weeks after vaccination.

Stay away from sick children. Parents of sick children should not let their children eat the food they get. Don't let the baby touch anything that may be infected with the virus. Diarrhea is common in autumn. It is best not to take children to play in crowded places.
