What are common side effects of vaccinations?

The common side effects of vaccinations typically include soreness at the injection site, mild fever, and fatigue. These reactions are generally mild and occur as part of the body's immune response to the vaccine. The soreness at the injection site is a localized reaction where the body is responding to the foreign antigens introduced by the vaccine. Mild fever can occur as the immune system activates, and fatigue might result from the immune response as well.

While severe allergic reactions and fainting can occur, these are less common and not typically classified as common side effects. They are more serious outcomes that require immediate medical attention. Long-term chronic conditions resulting from vaccinations are quite rare and not considered a normal side effect. Thus, the choice highlighting soreness, mild fever, and fatigue accurately reflects the most frequently observed and expected reactions following vaccination.
