Adverse Effects of COVID 19 Vaccine
The COVID-19 vaccines all have similar adverse effects. Rare, severe allergic reactions, including Anaphylaxis , have been reported. Other adverse effects are common: Injection site pain, swelling, and redness Fatigue Headache Muscle and joint pains Fever and chills Nausea Malaise Lymphadenopathy Adverse effects typically last several days. Reactive lymphadenopathy may occur after COVID-19 vaccination and may result in a false-positive reading on mammography. Multiple studies have been done, and the most recent recommendation from the Society of Breast Imaging, released in February 2022, recommends no delay between COVID vaccination and screening mammogram (seeSociety of Breast Imaging: 2022 Position Statements and Recommendations: Revised SBI Recommendations for the Management of Axillary Adenopathy in Patients with Recent COVID-19 Vaccination).
