Suspension of influenza vaccination … Distribution process problem
Exposure to room temperature for some vaccines … Concerns about decreased effectiveness of medications
Corona 19 vaccine is more difficult to distribute than flu vaccine
[앵커]
As the development of the COVID-19 vaccine is entering the field of view, interest is growing in the method of distribution after vaccine manufacture and mass production technology. In particular, it is noted that the Pfizer vaccine should be distributed and stored at -70 degrees Celsius. This is Lee Sung-kyu. The flu-free vaccination, which began in September, was temporarily suspended due to problems in the distribution process. Concerns have been expressed that some vaccines are exposed to room temperature and their effectiveness has decreased. Compared to the flu, the COVID-19 vaccine has a much more difficult distribution process. Both the vaccine developed by Pfizer and the vaccine manufactured by Modena are vaccines that use RNA, the viral genome, and cryogenic storage is vital due to nature. The Pfizer vaccine should be stored at -70 ~ 80 ℃, and the modder or vaccine should be stored at -20 ℃ for safety. Compared to influenza vaccines that must be stored and distributed around 4 ℃, the storage temperature is significantly lower. However, RNA vaccines have not been commercialized so far and there is no experience of vaccine distribution worldwide at -20 ° C or 70 ° C. Therefore, the provision of special storage boxes for freezers worldwide is an immediate problem. There is an urgent need to prepare related standards in Korea. After all, a common point of experts is that there is still a lot of work to be done before a poorly developed vaccine goes through manufacturing, mass production and finally distribution.
