Who is most likely to experience adverse events from vaccination?

• A. Individuals with a general good health status
• B. Those with a history of severe allergies or compromised immune systems
• C. People who have never been vaccinated before
• D. Individuals who are physically active

Answer: (B)

Individuals with a history of severe allergies or compromised immune systems are most likely to experience adverse events from vaccination due to their unique health challenges. Those with severe allergies may have an increased risk of anaphylactic reactions to certain vaccine ingredients, such as egg proteins, preservatives, or adjuvants. For instance, patients with a known allergy to polyethylene glycol (PEG), which is found in some vaccines, require careful consideration before vaccination. Moreover, individuals with compromised immune systems, whether due to a medical condition (like HIV/AIDS or cancer) or treatments (such as chemotherapy or immunotherapy), may also respond differently to vaccines. Their bodies may not be able to mount an adequate immune response, increasing the likelihood of adverse reactions. They may also be at risk for infections when receiving live-attenuated vaccines. In contrast, people with good health status or those who are physically active generally have a robust immune system that can handle vaccinations well. Furthermore, individuals who have never been vaccinated are not inherently at higher risk; they may just have a lack of prior exposure, which does not directly correlate with experiencing adverse events. Hence, the group that warrants the most caution regarding adverse events from vaccinations is indeed those with severe allergies and compromised immune systems.
