The refrigerator where the frozen vaccine is stored is out of power, is it okay to refreeze the vacc

Such a vaccine should no longer be frozen, because the refrigerator has been blacked out, I don't know how much the temperature can reach, and there is no guarantee that the vaccine will be good for patients, so it should be disposed of in time.

Hello: Vaccine'sSecurity] is very important, out of the optimal storage temperature, it will fail (or go wrong), and refreezing will not help!

In general, the typhoid vaccine must be kept in the refrigerator at a temperature of 2 to 8 degrees Celsius (Celsius to Fahrenheit), and if the vaccine is left at room temperature, it will lose its effectiveness. Of course, the standard temperature of different vaccines may be different, so it is necessary to strictly abide by the safety and health management regulations.

1. Almost all vaccines for veterinary drugs in small and large animals, including those in lyophilized and liquid form, must be stored in a dark environment between 35 degrees Fahrenheit and 45 degrees Fahrenheit. Technicians working with frozen vaccines should contact the manufacturer for specific storage instructions.

2. Vaccines that need to be refrigerated must be stored in a designated refrigerator, which should be a standard-sized refrigerator with a separate freezer compartment and not a small dormitory-style refrigerator to ensure better temperature control. Therefore, the vaccine should be kept in the refrigerator**, far enough away from the freezer compartment to prevent freezing. Additionally, storing a jar of water in the refrigerator can also help prevent temperature fluctuations.

3. The vaccine should be kept in its original packaging and the box should be rotated so that the latest batch is on the back and used last. Food and beverages should not be stored in the vaccine refrigerator and should not violate occupational safety and health management regulations. In addition, frequently opening the refrigerator to remove food can also cause temperature fluctuations.

If the temperature exceeds or falls below the recommended range, an immediate investigation is required and it should be confirmed that the door is well sealed and closed tightly. If necessary, the thermostat should be adjusted, and if necessary, electrical maintenance personnel should be called. And, the exact temperature and the measures taken should be recorded in a logbook.

In conclusion, vaccines are sensitive to heat and freeze and have special requirements for storage before use. Be sure to check the shelf life of the vaccine product, follow the label instructions, and make sure the vaccine is kept at the proper temperature before use. From the time the vaccine is purchased, to the time it is transported and stored, until it is used, the vaccine needs to be kept cold and dark.

If you're using a refrigerator to store your vaccine, to make sure it's working effectively, put a thermometer in it and check it regularly. By understanding these potential "weaknesses" in the vaccine protocol, technicians can help ensure that vaccines are not lost due to improper handling.

First of all, let me give you a popular science, all vaccines on the market are heat-sensitive biological products, generally speaking, the temperature of storing vaccines and transporting vaccines in various countries is between 2 degrees and 8 degrees, and this temperature is also the most recommended temperature for storing vaccines. However, it is worth mentioning that even at the recommended storage temperature, the vaccine will still be invalid, which is the shelf life of the vaccine at the recommended temperature, which is what we call the expiration date.

If the vaccine is stored above the recommended storage temperature, the vaccine will fail faster, so if the vaccine is improperly stored or not refrigerated, the vaccine will expire before the expiration date is reached, or even faster! According to the different heat sensitivity of different vaccines, live attenuated vaccines are more susceptible to temperature than ordinary inactivated vaccines. Therefore, if the vaccine is not refrigerated, the expiration time is related to the nature of the vaccine.

Here we can give an example to illustrate, take some basic vaccines as an example, the rabies vaccine and hepatitis A vaccine on the market can be stable for 1-3 weeks in an environment of 37 degrees if they are not refrigerated, which means that this type of vaccine will be ineffective in 1-3 weeks without refrigeration. The live attenuated vaccine is only stable for 12 hours at 37 degrees, which means that this type of vaccine will be ineffective after 12 hours when it is not refrigerated.

Therefore, for the immune response and potency of the vaccine, the refrigeration procedure is very important. However, we must regulate a concept, that is, not all unrefrigerated vaccines or improperly refrigerated vaccines will definitely fail, which mainly depends on the nature and status of the vaccine itself. We don't want vaccines to fail, let alone imagine the consequences of unrefrigerated vaccines.

If the vaccine is not refrigerated and invalid, then the most direct consequence is that there will be no effect after receiving this vaccine, there is no immune response, this is not directly fatal, and parents should be clear that the ineffective vaccine will not be directly fatal!

After the refrigerated vaccine is taken out of the refrigerator, it is injected in time to avoid invalidation, which will affect the immune effect and cause vaccination failure. If the room temperature exceeds 30 degrees Celsius at the time of injection, it should generally not exceed 10 minutes, because the storage temperature is exceeded, and the inoculation may become invalid.

The storage temperature of the vaccine needs to be between 2-8 degrees, and it should be stored in the dark, and it will not be effective for more than half an hour after leaving the refrigeration at a higher room temperature.

Because the vaccine is made of live attenuated pathogenic microorganisms, or made of inactivated pathogenic microorganisms or their metabolites, most of its ingredients are proteins, afraid of heat and light, because light and heat can lead to the degeneration of the egg banquet Yanyan Baixiaoqi, once the live vaccine is inactivated, it will lose its original immune effect, and the invalid epidemic Xiangxiang high seedling inoculated into the human body will not produce immune effect.

Therefore, in the process of storing and transporting vaccines, it is necessary to ensure that the whole process is in a refrigerated environment, and individual vaccines need to be frozen and stored. In addition, the vaccine can tolerate the external room temperature for a certain period of time, but it cannot be separated from the cold chain for a long time, so in order to ensure the effectiveness of the vaccine, it needs to be refrigerated during storage and transportation.

Question 1: Why do vaccines for vaccination be frozen Most vaccines are stored (refrigerated) at 2-8 degrees Celsius. Sugar pills (live attenuated polio vaccine) are frozen at -20 degrees Celsius.

Vaccine is a biological product, and too high temperature will affect the protective effect of the vaccine, so that the vaccine effect is reduced or ineffective, so the vaccine needs to be stored at low temperatures.

Question 2: Is the pet vaccine quick-frozen or refrigerated in the refrigerator? Different wide disturbance, depending on what brand of seedlings you buy, if it is imported, it needs to be refrigerated, but if it is domestic, it needs to be frozen.

It is recommended not to buy domestic vaccines, not because they do not support the domestic industry, but because the vaccination failure rate is really high.

Question 3: Do Hongqiaozhi Class II vaccines need to be refrigerated Hello, I am an immunization doctor Not only does the second type of vaccine need to be refrigerated, but the first type of vaccine also needs According to the cold chain management regulations of the immunization program, all vaccines should be stored below minus 20 degrees Celsius for long-term storage, and if they are stored for a short time, they should be stored at 2 8 degrees Celsius

Question 4: Can the refrigerated vaccine still be used if it is frozen Look at the label of the vaccine bottle, there is a storage temperature on it, some are minus 15 degrees, and some are 2-8 degrees. Dog vaccines are frozen and refrigerated, if they are frozen and not broken bottles, they can be used, but if refrigeration is required, they cannot be used after freezing.

Question 5: The storage of township-level vaccines with refrigeration conditions generally does not exceed how long This is related to the actual validity period of the vaccine, the cold chain storage conditions and the need for emergency vaccination, etc., to determine the number of vaccines stored in the national immunization program. In principle, the stockpiles of vaccines at all levels are:

6 months at the provincial level, 3 months at the municipal level, 2 months at the county level, and 1 month at the township level with refrigeration conditions.

Question 6: The vaccine is refrigerated, and if it is put in the freezer, will it be bad It depends on what vaccine, hepatitis B vaccine, BCG, and diphtheria-tetanus-pertussis vaccine cannot be frozen! If it is a lyophilized vaccine, such as leprosy vaccine, cerebral flu vaccine, etc., cryopreservation is also acceptable.

Question 7: What are the ways to use vaccine refrigerated bags Try to describe the use of refrigerated bags (boxes)? (1) Polio vaccine and measles vaccine are placed on the bottom layer of a refrigerated bag (box);

2) BCG is placed in the middle layer and has a striking mark;

3) Diphtheria, tetanus, tetanus, and hepatitis B vaccines should be placed on the upper layer, not close to the ice row, to prevent freezing.

4) The polio vaccine is packed in a plastic bag, the vaccine and diluent without a box are wrapped in gauze, and the space in the refrigerated bag is filled with gauze or paper to prevent the vaccine ampoule (bottle) from oscillating and rupturing.

5) Other vaccines should be stored at the storage temperature specified in the vaccine instruction manual, with reference to the above requirements.

Question 8: Crazy vaccine frozen or refrigerated Refrigerated roots need to be thawed, not that it must be ice to thaw. Half of the frozen meat is meat or something, and refrigeration highlights a freshness. Write post-thaw intramuscular injection above

According to the cold chain management regulations of the immunization program, the long-term storage of vaccines should be stored below minus 2 trillion degrees Celsius.

Vaccines refer to vaccine-type preventive biological products used for human vaccination in order to prevent and control the occurrence and epidemic of infectious diseases. Biological products refer to preparations prepared for prevention, diagnosis and use of microorganisms or their toxin bonds, enzymes, human or animal serum, cells, etc. Biological products used for vaccination include vaccines, vaccines and toxoids.

Among them, the seedlings made of pathogens are seedlings; Viruses, rickettsia, and spirochals are made up of vaccines, and are sometimes collectively referred to as vaccines.

It depends on what vaccine, some vaccines have a longer shelf life and can be refrigerated for a longer time, but to ensure that the shelf life has not passed, I used to take the hepatitis B vaccine, and I kept it in the refrigerator for a long time.

Each Destiny vaccine has its own storage requirements, depending on whether it has been stored in the refrigerator for longer than the period of storage of the vaccine, and whether the temperature of the refrigerator is suitable for the storage of this vaccine. These will affect the effectiveness of the vaccine, and if there is a mistake in any link, the vaccine cannot be used.

Second, there are also different effects on the duration of cold break (e.g., the potency of the sugar pill vaccine will be significantly reduced after 1 day under 37, and it will be reduced to 0 after 5 days).

Thirdly, if it is left at room temperature for a long time, it will not be able to guarantee its activity, and the vaccine will be the same as an ineffective counterfeit drug.

Fourth: the impact of different vaccines on people after the invalidation is also different, some will be just ineffective drugs, not much, but some will cause serious harm to people.

For an emergency like yours, the power goes off in the middle of the night, and if the call comes in the morning, it won't make much of a difference.

The storage of the ring vaccine is 2-8 degrees Celsius, and the refrigerator cannot be used under normal conditions after the power is off, so it is recommended to replace it again.
