Janssen/Johnson & Johnson Side effects
Injection site pain, fatigue, headache, muscle pain, chills, fever and nausea
Note: If you received this vaccine within the last three weeks and are experiencing any unexplained new severe symptoms, seek emergency care.
Use of the Janssen/Johnson & Johnson COVID-19 vaccine might increase the risk of a rare and serious blood clotting disorder. Nearly all of those affected have been women ages 18 to 49.
As a result, the CDC recommends getting an mRNA COVID-19 vaccine over getting the Janssen/Johnson & Johnson COVID-19 vaccine. Research suggests there isn’t an increased risk for this disorder after mRNA COVID-19 vaccination.
Possible severe symptoms include shortness of breath, persistent stomach pain, severe or persistent headache, blurred vision, chest pain, leg swelling, easy bruising, and tiny red spots on the skin.
Rarely, some people may develop Guillain-Barre syndrome after getting the vaccine. Seek immediate medical care if you have weakness or tingling sensations, difficulty walking, difficulty with facial movements, double vision, and difficulty with bladder control.
