read the article linked in the thread. it actually does not work against all of the covid virus. it works against the spikes.

so, the virus is sort of like a ball with these spikes on top (that’s where the corona name comes from) and the vaccine helps your body develop antibodies against the spikes. so when the virus gets in your body, it actually receives a “haircut” which leads to it no longer being able to enter the cells and hijack their internals to produce more viruses.

it’s extremely clever, but it also means that your code is wrong ;))
