The medicine than can give you immunity to diseases is vaccine. Although antibiotics help treat kill or prevent bacterial infections from multiplying in our immune system, it is not enough to give our body immunity from certain diseases. Vaccines contain antigens that cause the body to develop immunity, and the diseases that they prevent are either dangerous or deadly. Vaccines help our immune system to recognize and destroy infections in our immune system.
There are different types of vaccines such as: live, attenuated vaccines, which are weakened microbes that produce lifelong immunit. Inactivated vaccines are dead microbes and often have to be followed by booster shots because it elicits a weaker immune response compared to live vaccines, toxoid vaccines are used where infections are caused by organisms secreting harmful toxins in the body, conjugate vaccines are used for bacteria that are not recognized by the immune system, recombinant vector vaccines are used to target complex infections, subunit vaccines helps evoke an immune response, and DNA vaccines are used to help the immune system recognize the virus and develop immunity.
