Yeah, that’s accurate. Vaccines rely on the spike protein of SARS-CoV-2 to induce immunity. But such spike protein is modified so that it won’t bind to the ACE2 receptor like the real actual virus’s spike protein.

Yet, many people think that vaccines directly inject the actual virus’s spike protein, which led to the misunderstanding that vaccines are as dangerous as the virus’s spike protein. Please feel free to see the article I mentioned earlier, all the evidence about this are linked therein.
