In order to do a good job in expanding the national immunization program in the province, maintain the low-temperature storage and transportation of immunization vaccines in centers for disease prevention and control at all levels and designated vaccination units, and ensure the safety and effectiveness of vaccinations, special Formulate the "Anhui Provincial Immunization Program Cold Chain System Equipment Configuration Guidance Plan (Trial)". 1. Principles of cold chain equipment configuration 1. The equipment is intended for disease prevention and control centers at all levels and designated vaccination units responsible for vaccine storage, transportation and use. 2. The equipped cold chain equipment can meet the storage and transportation needs of each unit's immunization program vaccines and appropriate amounts of second-class vaccines. 3. Maximum vaccine (including diluent, the same below) storage volume: According to the provincial disease prevention and control agency, it is 1/2 (6 months) of the province’s annual vaccine demand, and the city and county-level disease prevention and control agencies are the jurisdictions Within 1/4 of the annual vaccine demand (3 months), the vaccination unit is 1/6 (2 months) of the annual vaccine demand. Calculate the cold chain equipment volume and transportation tools required by disease prevention and control institutions at all levels. . 4. In the event of a power outage or damage to the cold storage unit, the normal operation of the cold storage can be restored in a short time. 2. Calculation method of refrigeration volume (including freezing, accounting for approximately 1/10 of the volume, the same below) 1. Calculation is based on each child receiving 22 doses of the immunization plan vaccine and the vaccine volume is 1L. 2. To ensure effective space for cold storage and refrigerators, the refrigeration capacity is calculated as 4 times the vaccine volume. 3. Specifications of equipment for cities, counties and vaccination units: ordinary cold storage equipment is 15M3, low-temperature cold storage is 8M3, ordinary refrigerators (including refrigeration and freezing) are 250L, low-temperature refrigerators are 250L, and refrigerated trucks are 4-8M3. 3. Equipment standards for each cold chain equipment 1. Refrigerated truck: 1 vehicle for each municipal disease prevention and control institution, and 1 vehicle for county-level disease prevention and control institutions with more than 5,000 children born per year. 3 vehicles at the provincial level. 2. Vaccine transport vehicle: Each municipal and county-level disease prevention and control agency is equipped with one vehicle. 3 vehicles at the provincial level. 3. Low-temperature cold storage: provincial equipment 200M3. Each municipal disease prevention and control institution is equipped with one facility, and each county-level disease prevention and control institution with more than 5,000 children born per year is equipped with one facility. For county-level CDCs that are not equipped with low-temperature cold storage, one low-temperature refrigerator should be equipped for every more than 2,000 children born per year. 4. Ordinary cold storage: Each municipal and county-level disease prevention and control institution is equipped with at least one. For municipal and county-level disease prevention and control institutions with more than 20,000 children born per year, one additional facility will be added for every 20,000 children born. Provincial level equipment exceeds 800M3. 5. Refrigerators: Each township-level vaccination unit is equipped with 2 units. For vaccination units that serve more than 500 children born per year, the corresponding number of refrigerators will be increased by 1-2 units. The vaccination unit responsible for the first dose vaccination of hepatitis B vaccine and BCG vaccine, but not the vaccination of other immunization programs, is equipped with 1 set. 6. Backup generator: Each city-level and county-level disease prevention and control agency is equipped with one. 3 provincial-level equipment. 7. Standby normal temperature cold storage refrigeration unit: Each city-level and county-level disease prevention and control institution is equipped with one unit, and urban and county-level disease prevention and control institutions are not equipped. 3 provincial-level equipment. 8. Automatic temperature recorder: Each refrigerated truck and each cold storage are equipped with one. 9. Refrigerator: 1 equipment per county for every 1,000 additional children born per year. 10. Refrigerated packs: Each township-level vaccination unit is equipped with 5 kits if the number of vaccination targets is greater than 300 children born per year, and 3 kits if the number of vaccination targets is less than 300 children born per year. 11. Please see Appendix 1 for the equipment standards of disease prevention and control institutions at all levels. 4. The standard quantity of cold chain equipment for each city, county (city, district) disease prevention and control institution. According to actual work needs, the number of cold chain equipment and equipment of each vaccination unit in the province is included in the county-level disease prevention and control institutions. If there are new vaccination units, the municipal disease prevention and control centers are required to summarize the data of each county and report it to the Immunization Planning Section of the Provincial Center for Disease Control and Prevention before the end of October each year so that cold chain construction can be arranged in a timely manner.

For details, please refer to the attached table for the equipment standard of provincial cold chain equipment at all levels.

For every more than 20,000 children born per year, one vehicle will be added 10211. For those with more than 5,000 children born per year at the county level, one vehicle (4-7M3) will be equipped 11. For every more than 20,000 children born per year, add one more. For every more than 5,000 children born per year, equip one low-temperature cold storage. For every more than 2,000 children born per year, add one cold storage. 1. For every unequipped urban area 1 with more than 1,000 children born per year, one vaccination clinic 2 will be added. More than 5,000 children born per year, an appropriate increase of 3-5
