What common side effect might patients experience after receiving a vaccination?

After receiving a vaccination, patients may commonly experience fatigue as a side effect. This symptom of tiredness or exhaustion is a typical response to immunization as the body initiates an immune response to the vaccine. The fatigue often reflects the body’s efforts in producing antibodies and is usually mild and temporary, resolving within a few days.

In the context of the other options, while headache, skin rash, and joint swelling can occur with some vaccines, they are less frequently reported or may occur at lower rates compared to fatigue. Thus, fatigue stands out as a more prevalent and expected reaction within the general population following vaccination. Understanding these common side effects can help healthcare providers manage patient expectations and encourage individuals to stay informed about what to anticipate after receiving vaccinations.
