...... mRNA, like its name, is a messenger that contains information how our body should make something. Then our body make it, and detect it as a foreign protein. Then our body will make that newly created foreign protein as "punching bag" as I said before. Everything from that points remain the same. Our body will know which part to attack when it receives real virus.

That leads me to re-think about the core question: how effective of this kind of mRNA-based Covid19 vaccines?

For example, it would take time for our bodies to create that SARS-CoV-2 spike protein on our own and then detect it as a foreign protein. And God knows how long this mechanism will be last for.

Now it seems more and more people in the U.S. have taken the vaccines but the number of inflected cases is still not dropping.
