For example, the smallpox vaccine is based on live vaccina virus while the polio vaccine is formulate with breathless poliovirus.

These vaccines, especially the chemically inactivated formulations, flourishingly generate protective antibody results. However, these vaccines as well contain many antigens which may divert the immune repartee from protective antigens. Nevertheless, many of the pathogens enc ountered by society to date correct forwar! d be protected using antibody responses and therefore these approaches have generated successful vaccines. Lifestyle Choices In regards to cancer, we have yet to develop successful therapeutic and prophylactic vaccines. Lifestyle choices remain our opera hat alternate to preventing cancer. The American Cancer Society (4) has published a impudently set of recommendation for cancer prevention.
