Anticoagulants can be dangerous if taken improperly and without medical supervision. They need constant monitoring during therapy. Blood clots following COVID-19 vaccines are a very rare phenomenon and do not justify prophylaxis with anticoagulants.
The most common side effects following COVID-19 vaccines are fatigue, a fever, headaches, body aches, chills, nausea, diarrhea, and pain at the site of injection, according to the World Health Organization.
These may last from a few days to a week and are mostly self limiting.
Take medication as prescribed by your doctor and rest. You can keep a clean wet cloth on the affected area to reduce pain. Consult your doctor if redness, tenderness, or swelling of the hand worsens.
Drink plenty of fluids to stay hydrated.
Avoid doing strenuous activities for at least 3-4 days after getting the vaccine. It is safer to avoid alcohol and smoking for a few days.
The vaccine does not fully prevent infection by the COVID-19 virus. However it drastically reduces the chances of severe life threatening consequences and death due to COVID-19.
Next Steps
