About vaccination. I have low immunity?

No, there is absolutely no correlation between severity of symptoms and immunity level. You're good to go. Please continue your daily activities and maintain COVID-19 appropriate precautions such as social distancing.

You can start tablet PARACETAMOL 500MG thrice a day after meals provided you have no prior reaction to the medication.

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 or an icepack on the affected area to reduce pain. Consult your doctor if redness, tenderness, or swelling of the hand worsens. Do not rub the injection site. 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.
