there are many

many potential vaccines for COVID-19

Several different types of potential vaccines for COVID-19 are in development, including:

• Inactivated or weakened virus vaccines use a form of the virus that has been inactivated or weakened, so it doesn’t cause disease, but still generates an immune response.
• Protein-based vaccines use harmless fragments of proteins or protein shells that mimic the COVID-19 virus to generate an immune response safely.
• Viral vector vaccines, which use a virus that has been genetically engineered so that it can’t cause disease, but produces coronavirus proteins to generate an immune response safely.
• RNA and DNA vaccines, a cutting-edge approach that uses genetically engineered RNA or DNA to generate a protein that safely prompts an immune response.

The Pfizer vaccine prevents getting it, but the ivermectin (medicine, if you can find it) kills it in 1 or 2 days.
