Vaccines can be made to combat bacteria (like pneumococcus, a bacteria species that is the leading cause of pneumonia) and viruses (like measles, the most infectious disease known). A vaccine may use either attenuated (weakened) strains of the bacteria or virus, or purified structures of the bacteria or virus. By being primed against the invader, the body is ready to respond in the case of actual exposure to infection. Both types can provide long-lasting protection from infection. Although most vaccines are for infections that, if survived, the body has immunity to, some vaccines provide immunity to an infection that even survivors do not develop immunity to. One example is tetanus.

Vaccines teach the immune system how to make antibodies to a particular infection, and may also stimulate the cellular immune system. The way this works is complicated, and physicians spend months learning how the immune system works and how vaccines interact with the immune system. By contrast, vaccine scientists spend years or decades learning in great detail how to make safe and effective vaccines.

At the time I write this, I know of many different teams trying heroically to develop a safe and effective vaccine against coronavirus. A vaccine could prevent millions of deaths. As a provider on the front line of taking care of these patients, I cannot express how much I look forward to a vaccine. As a person in their 80s, you should, too.
