(HealthNewsDigest.com) – COVID-19 vaccines can cause mild side effects after the first or second dose, including:
- Pain, redness or swelling where the shot was given
- Fever
- Fatigue
- Headache
- Muscle pain
- Chills
- Joint pain
- Nausea and vomiting
- Swollen lymph nodes
Most side effects happen within the first three days after vaccination and typically last only 1 to 2 days.
In the U.S., there has been an increase in reported cases of myocarditis and pericarditis after mRNA COVID-19 vaccination, particularly in male adolescents and young adults age 16 and older. Myocarditis is the inflammation of the heart muscle, while pericarditis is the inflammation of the lining outside the heart. These reports are rare. The CDC is investigating to see if there is any relationship to COVID-19 vaccination.
Serious side effects of the Janssen/Johnson & Johnson COVID-19 vaccine can occur within three weeks of vaccination and require emergency care. Possible symptoms include:
- Shortness of breath
- Persistent stomach pain
- Severe or persistent headaches or blurred vision
- Chest pain
- Leg swelling
- Easy bruising or tiny red spots on the skin beyond the injection site
Mild to moderate headaches and muscle aches are common in the first three days after vaccination and don’t require emergency care.
Rarely, some people may develop Guillain-Barre syndrome after getting the Janssen/Johnson & Johnson COVID-19 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.
