Can adults receive the pertussis vaccine?

　　"Can it be administered?" usually refers to whether vaccination is permissible. Generally speaking, adults can usually receive the pertussis vaccine if they are not allergic to it. However, if an individual is allergic to the vaccine, they should not receive it. If any physical discomfort occurs after receiving the pertussis vaccine, prompt medical attention is recommended. Detailed analysis is as follows:

　　1. Can be vaccinated

　　Adults who are not allergic to the pertussis vaccine can generally receive it. After vaccination, they can effectively prevent pertussis and reduce the risk of infection, thereby protecting both their own health and that of those around them. The pertussis vaccine stimulates the body's immune system to produce antibodies, enhancing resistance against Bordetella pertussis.

　　2. Cannot be vaccinated

　　If an adult has an allergic reaction to the pertussis vaccine, they should not receive it. Allergic reactions may manifest as severe symptoms such as skin itching, difficulty breathing, or laryngeal edema, and in extreme cases could even be life-threatening. Therefore, before vaccination, individuals should inform their doctor about their allergy history and undergo necessary allergy testing. If test results indicate a risk of allergy, pertussis vaccination should be avoided to prevent unnecessary health risks.

　　In summary, individual allergy status is a critical factor to consider when deciding on pertussis vaccination. Only under conditions ensuring safety can pertussis be effectively prevented and good health maintained.
