Adult vaccination: The shots you need
The 10 vaccines listed below protect against some of the most common and serious ailments that afflict Americans, including the flu, which sends more than 200,000 people to the hospital each year and kills more than 35,000. Some of the other diseases aren't likely to kill you, but can be extremely painful and flare up with no warning. And when the usual childhood diseases occur in adults, the effects can be devastating. Though many people fail to get an annual flu shot, a vaccine against the disease has been available for more than 60 years. Other vaccines, including one against shingles and another that helps to protect against cervical cancer, came out fairly recently. All the vaccines listed below are generally very safe and effective, though many adults aren't aware that they need them, aren't being reminded by their doctors, or are skeptical about their safety and effectiveness. But even if you are healthy and willing to forgo a shot and risk getting sick, vaccinating yourself protects vulnerable family members, friends, and coworkers from catching diseases that could be potentially deadly to them.

This chart will tell you which adult vaccines to consider, based on your personal situation. In addition to the few vaccine-related complications listed below, any vaccine can cause temporary, minor reactions such as a mild fever or soreness or swelling at the injection site. And any vaccine (or one of its inactive ingredients) can, in rare cases, cause an immediate, serious allergic reaction known as anaphylaxis. If you've had such a reaction, avoid the vaccine unless your doctor determines that the shot's benefit for you outweighs its risk.
