Should I vaccinate the wheel virus vaccine?

Recently, my friend’s baby was vomiting, burning and diarrhea, and the whole family was in a anxiety, busyness and heartache.

“I’m going crazy!” “Why is this?” “How long can the baby be good?” Friends complained to me countless times.

I told her: “Babies of more than seven months, at this time, we must first consider rotary virus infection. For rotor virus infections, it is mainly symptomatic supporting treatment to prevent dehydration. At present, there is no better treatment. It takes at least a week. “

Friends are very obedient. On the one hand, I reported the changes in the condition at any time, and on the other hand, I strictly followed my instructions. Nevertheless, whenever you look at the child’s pain, the whole family still cannot be calm, both guilt and regret! Last night, Bao Ma regretted saying: “Blame me, I did not vaccinate the wheel virus vaccine at the beginning!”

What is a rotary virus infection?

Rotating virus infection is one of the most common causes of gastroenteritis in the age of 2 in the clinic. The disease has a typical epidemic season. It is common from mid -to -late October to February of each year. The first cause of diarrhea in children.

About 400 million people (1.11 to 135 million children) around the world suffer from wheeled virus enteritis, of which about 800,000 children die; about 18 million children in my country have rotary virus enteritis, of which about 30,000 to 40,000 are Children died of the disease.

Know the wheel virus

1. Roman virus classification

Roman virus is divided into seven groups of groups A, B, C, D, E, F, G. Among them, group A, B, and C can infected humans but group A is an important pathogenic cause of infants and young animals, which can cause acute and autopsy diarrhea. In the epidemic season, the infection rate of the round virus in group A is as high as 90%. It should be noted that after the infection of a rotary virus, there are still many possibilities of infection.

2. Infection pathway

Roman virus is mainly transmitted in dung-oral channels. In addition, the virus particles exist in air in the air, and can also be transmitted through the respiratory tract.

3. Clinical manifestations

The incubation period of cytitis enteritis is 1-3 days, and there are many onset of onset. The typical symptoms are vomiting, fever and non-hemorrhoid diarrhea. On the first day of the disease, there will be vomiting and fever first, and then diarrhea will occur. The stool will be more than 3 to 10 times a day. The bowel movements are urgent and large, and the dung is mostly pale yellowish water or egg flower soup. Occasionally there are mucus, and there will be no pus and blood.

Roman virus enteritis can perform different weights. Those who are light can have no fever and vomiting, only mild diarrhea, and may even have no obvious symptoms. In severe cases, dehydration and electrolyte disorders, metabolic acid poisoning, and even intestinal cases can be dehydrated due to fever, continuous vomiting and water -like aspiration.

In addition to gastrointestinal symptoms such as vomiting, diarrhea, and diarrhea, rotatitis may also have respiratory symptoms, central nervous system symptoms, heart damage, liver and kidney damage.

The natural course of the natural diseases of rotary viruses is about a week. A few can be up to 2 weeks. Generally, the prognosis is good, but those with severe dehydration and not active treatment can also cause death. People with immune defects often turn into chronic diarrhea or severe infection due to mixed infections or severe infections. disease.

4. Treatment method

Roman virus infection is a self -limited disease. There is currently no special drugs and treatment methods. It is mainly symptomatic support. The key to treatment is to prevent dehydration and electrolyte disorders.

Development background of wheeled virus vaccine

Roman virus infection is global and almost spread throughout all countries and regions; and perfect sanitary facilities and good sanitary conditions do not prevent the spread of rotavirus. Virus vaccine is the best way to reduce the incidence of severe diarrhea and death.

The development of rotary virus vaccines is the primary task of the World Health Organization Vaccine Development Plan. However, after years of exploration and clinical practice, there are three types of wheeled virus vaccines that are currently being promoted. There are two types of abroad, including “five-valent-cattle wheel-like virus restructuring vaccine (RV5)” and “poison-reduced human wheeled virus vaccine (RV1)”, while only one in China: oral wheel virus live vaccine.

Protection effect of rotary virus vaccine

According to research reports, the protection rate of gastrointestinal gastroenteritis in rotor virus in my country’s oral rotavirus vaccine is 72 %; the protection rate of severe diarrhea caused by rotor virus is 70 %. It can not only reduce the incidence of rotavirus diarrhea, but also reduce the occurrence of severe cases.

According to relevant foreign studies, rotor virus vaccines can prevent the occurrence of rotavirus gastroenteritis very effectively; reduce related hospitalization and medical services; and due to children’s inoculation, adult rotavirus infections are also significantly reduced.

However, due to the variant of rotary virus, and the fluorotic strain in different periods in different regions may be different, which can cause the same vaccine to prevent the effect of prevention in different periods in different regions.

Can “oral virus vaccine” inoculate at the same time as other vaccines?

The World Health Organization recommends that the rotavirus vaccine can be vaccinated at the same time as other vaccines in the child’s immune procedure. Studies of the National Institute of Health showed that: wheeled virus vaccines and Baibai breakthrough vaccines (DTP), spinal cordyllaritis and active vaccine (IPV), and influenza Hemodobaccylla vaccina (HIB) were vaccinated at the same time. It does not affect infants and young children to respond to antibodies of each vaccine.

The vaccination plan of different rotavirus vaccines is different. At present, the domestic oral rotavirus vaccine for group A’s wheel virus is used. The effective protection rate is more than 70%.EssenceGenerally, antibodies are produced 2 weeks after taking the vaccine. At 4 weeks, the antibody concentration reaches the highest peak. After the vaccination is successful, the protection period is generally one year. Therefore, it is recommended that babies within three years of age.Roman virus vaccine.
