Well Dah! That's how all vaccines work. They made from the DNA or the RNA of the virus. Little dead strands of DNA that'll flood your body so your immune system will learn to recognize the virus. And the only way your immune system will recognize the DNA in the vaccine as a threat, is to make you sick. That's why vaccines often make you feel like shit.

This is all high school level science. Didn't any of you pay attention in school? Unless you're Americans. The US education system has been shit for decades. That's why the vast majority of flat earthers are American.
