What are Delayed Schedule Vaccinations?

In the mid-1970s, China formulated the National Regulations on Immunization Work, which was included in the national health plan for universal immunization of children. Its main content is "four vaccines against six diseases", that is, the basic immunization of BCG vaccine, polio trivalent sugar pill vaccine, diabetic triple vaccine and measles vaccine for children seven years of age and younger, and timely immunization, so that children Get immune to tuberculosis, polio, whooping cough, diphtheria, tetanus and measles. In 1992, the Ministry of Health included the hepatitis B vaccine into the scope of planned immunization. As science and technology progress, planned immunization will continue to expand its content.

In the mid-1970s, China formulated the National Plan

1. Contents of Planned Immunization The main content of China's planned immunization work is to make "four seedlings prevent six diseases", that is, the basis for BCG, trivalent polio vaccine, diabetic vaccine and measles vaccine for children aged 7 and under Immunization and subsequent appropriate boosters will enable children to become immune to tuberculosis, polio, whooping cough, diphtheria, tetanus and measles. In 1992, the country added hepatitis B vaccine to the scope of planned immunization. Some provinces, municipalities, and autonomous regions have also incorporated the prevention of infectious diseases such as Japanese encephalitis, meningococcal meningitis, and mumps into planned immunization management.

2. Planned immunization program The immunization program refers to the types of vaccines to be vaccinated and the sequence and requirements of vaccinations. It mainly includes children's basic immunization and adult or special occupational populations, and special regions need vaccinations.

24 Within 24 hours of birth, get BCG vaccine and the first dose of hepatitis B vaccine.

1 month old, vaccinated against a second dose of hepatitis B vaccine.

(3) At the age of 2 months, the first polio vaccine was given.

3 months old, vaccinated against the second polio vaccine and the first diphtheria vaccine.

4 months old, vaccinated for the third polio vaccine and the second diphtheria vaccine.

5 months of age, the third vaccination.

6 months old, get a third dose of hepatitis B vaccine.

8 months old, vaccinated against measles.

1.5 to 2 years old, inoculated with Baibaipo.

4 years old, re-administered polio vaccine.

7 years old, multiple BCG vaccines, measles vaccine, hepatitis B vaccine, and boosted vaccination against tetanus. [1-2]

3. Expanded national immunization planning program In 2007, the country expanded the types of vaccines provided free of charge by the immunization program, increasing the original "five seedlings and seven diseases" to 15 infectious diseases. Hepatitis A vaccine, Japanese encephalitis vaccine, meningopolysaccharide vaccine, rubella vaccine, mumps vaccine, leptospirosis vaccine, epidemic hemorrhagic fever vaccine and anthrax vaccine were added.

1. Vaccination route and dose The vaccine route, the age of the vaccinated subjects and the dose are different. If immunization route and dosage are improper, it will not only affect the immune effect, but also increase the vaccination response and even cause vaccination accidents. Therefore, the vaccine instructions should be read in detail before vaccination.

2. Vaccine contraindications WHO requires contraindications for routine immunization if:

Immunodeficiency, malignant diseases (tumor, leukemia), and those whose immune function is suppressed by using radiation therapy or antimetabolites cannot use live vaccines;

The vaccination subject is suffering from acute disease with fever or obvious general discomfort, and vaccination should be postponed;

(3) Those who have had serious adverse reactions to previous vaccination should not continue vaccination;

Children with neurological diseases, such as epilepsy and infantile spasms, should not be vaccinated against pertussis antigens.

3. Vaccination response Biological products are a foreign body to the human body. After inoculation, they can cause a beneficial immune response, but can also cause adverse reactions or allergic reactions that are harmful to the body. The main side reactions are as follows:

General reaction Within 24 hours of vaccination, inflammatory reactions such as redness, swelling, heat, and pain appear in the vaccination area, sometimes accompanied by systemic reactions such as fever, dizziness, nausea, and diarrhea. These are generally normal immune responses and do not require any treatment and can disappear within 1 to 2 days.

A few people have abnormal reactions after vaccination, such as syncope, anaphylactic shock, allergic encephalomyelitis, allergic dermatitis, angioedema and so on. Although the incidence of these reactions is very low, the consequences are very serious. If they are not rescued in time, they can be life-threatening.

(3) Coupling disease has nothing to do with vaccination, but was mistaken for vaccination due to coincidence in time. [1]

"Implementation Plan for Expanding National Immunization Programs" by the Ministry of Health

In order to implement the spirit of Expanding the scope of the national immunization plan, including 15 types of infectious diseases that can be effectively prevented by vaccination, including hepatitis A and meningococcal disease, into the national immunization plan, which was proposed by Premier Wen Jiabao at the 5th Session of the 10th National People s Congress, expand the country The objectives and tasks of the immunization plan, standardize and guide the scientific implementation of the expansion of the national immunization plan, effectively prevent and control related infectious diseases, and formulate this plan.

I. Principles

Whether the Tibet, Qinghai, Xinjiang, and Xinjiang Production and Construction Corps will carry out JE vaccination will be reported to the Ministry of Health by the district health bureaus.

(4) Hepatitis A vaccine, measles gall breeze, cell-free dihydrotetracycline and other vaccines are temporarily unable to meet the vaccination of all children of appropriate age. Provincial health administrative departments (including Xinjiang Production and Construction Corps Health Bureau, the same below) according to the annual central special fund arrangement plan , The epidemic situation of the disease, and the feasibility of implementation, etc., choose the implementation area and implementation target. With the increase in the supply of vaccines, the scope of implementation is gradually expanded.

(5) The implementation scope of polio vaccine and measles vaccine booster immunization is determined according to the booster immunization implementation plan.

(6) The provinces will be determined according to the epidemic situation. Anthrax vaccine and Leptospira vaccine should be used for emergency vaccination when an outbreak of anthracnose, Leptospirosis or flooding may lead to an outbreak of Leptospirosis.

Implementation measures

(1) Strengthen leadership and organize the implementation and expansion of the national immunization plan.

Local health administrative departments at all levels should take the implementation of the expanded national immunization plan as their current priority and strengthen their leadership. It is necessary to formulate a specific implementation plan for expanding the national immunization plan in the region, and, under the leadership of the local people's government, together with relevant departments of finance, development reform, education, food and drug supervision, organize and implement the expansion of the national immunization plan.
