COVID-19 Vaccine Challegen: storage and transportation
COVID-19 Vaccine Challegen: storage and transportation. Some COVID-19 vaccines must be stored in a very low temperature environment to ensure its effectiveness. According to reports, Pfizer COVID-19 vaccine has stricter requirements and must be stored in an environment of minus 70 degrees Celsius.
General hospitals and clinics cannot provide such a low-temperature environment; even if some large medical schools have storage space that can guarantee minus 70 degrees Celsius, the space is very limited and cannot achieve sufficient reserves.
However, large hospitals and clinics can use dry ice to keep cold. Medical staff only need to replenish dry ice every 5-7 days, so that the vaccine can be stored for about two weeks. But for some small medical units, or hospitals with insufficient resources, it is estimated that it will be difficult to achieve.
Another point is the challenge of the transportation environment. If you live in a big city like ours, transportation will definitely be no problem. However, the United States is vast and sparsely populated, and there are still many people living in very remote places. This is important for the storage and transportation of vaccines. , Is a very big challenge, which is also an objective factor that restricts “universal immunity”.
