In almost all but a few cases, they are perfectly safe and cause only minor discomfort. There are times, however, when a person may experience an adverse response, often in the form of an infection or allergy.
Some may be minor and easily treated. Others may be far more serious and lead to a potentially deadly, all-body reaction such as anaphylaxis or sepsis. The symptoms can vary depending on whether the shot was delivered subcutaneously under the skin , intravenously into a vein or intramuscular into a muscle. Call your healthcare provider immediately if you experience any of the following symptoms.
