Difference between covid-19 vaccines . As of February 2021 , we have many kind of covid-19 vaccines , so , which one might we get? How do they differ?
The vaccines licensed by European and US regulatory agencies are generally considered safe. It is not possible to say that one of the vaccines is better for certain target groups or age groups than others.
The vaccines from Pfizer/BioNTech and Moderna are so-called mRNA vaccines. They replicate individual proteins in human cells that are typical for the virus, and the body reacts to this by building up an immune defense. The most important difference between the two vaccines: Moderna’s vaccine can be stored for up to 30 days in a normal household refrigerator.
It does not need to be refrigerated to -70 degrees Celsius (-94 Fahrenheit) during transport, like the vaccine from Pfizer/BioNTech. However, the latter can also be stored in the refrigerator for up to five days, just before using it.
AstraZeneca’s vaccine , however , is not an mRNA vaccine, but a so-called viral vector vaccine. It uses a harmless cold virus that normally infects monkeys as a transport mechanism. Thus, the vaccine transports the surface protein of SARS-CoV-2 to human cells, where it triggers an immune response against the coronavirus. A normal household refrigerator is also sufficient for this vaccine.
