Explanation:
Detailed explanation-1: -Live-attenuated vaccines Live vaccines use a weakened (or attenuated) form of the germ that causes a disease. Because these vaccines are so similar to the natural infection that they help prevent, they create a strong and long-lasting immune response.
Detailed explanation-2: -Vaccines contain killed, weakened, or synthetically manufactured versions of the disease-causing germ or parts of the germ called antigens. Some newer vaccines (e.g., COVID-19 mRNA vaccines) contain instructions for producing antigens rather than the antigen itself.
