Injection site reactions (ISRs) are a common localised side effect that can occur following the administration of any injected vaccine. They are an inflammatory response to the injected vaccine. Symptoms of ISRs include swelling, redness (erythema), induration (hardness), pain or itch at or near the injection site.<\/span><\/p>\n

Less commonly, significant or severe ISRs can present after an injection, extending over a greater area from \u2018joint-to-joint\u2019 (e.g. from the shoulder joint to the elbow joint) or \u2018crossing joints\u2019 (e.g. swelling that passes over one joint, such as the shoulder or the knee).<\/span><\/p>\n

High-g<\/span>rade<\/span> s\u1ed1t<\/span>S<\/span> are<\/span> not typically associated with ISRs.<\/span><\/p>\n

Diagnosis<\/h2>\n

A GP, immunisation specialist or immunisation provider can diagnose an ISR based on the clinical symptoms and timeline of presentation.<\/span><\/p>\n

ISRs typically occur within the first 48 hours following vaccination. Symptoms usually last 1 to 2 days and completely resolve within a week. In some rarer instances ISRs can last for a longer period of time (e.g. 5 to 7 days) or have a delayed onset (3 or more days after vaccination).<\/span><\/p>\n

Photographic evidence and monitoring the circumference of the affected area over time (e.g. draw around the ISR with a pen to see changes in circumference) can assist in documenting the progression of symptoms and support a diagnosis.<\/span><\/p>\n

Significant ISRs should not be confused with infections such as cellulitis. Symptoms consistent with cellulitis<\/span>,<\/span> such as decreased range of movement, lymphangitis (tracking of erythema), lymphadenopathy (swollen lymph nodes) and high-grade fevers<\/span>,<\/span> are not consistent with ISRs.<\/span><\/p>\n

ISRs are not an allergic response.<\/span><\/p>\n<\/div>
