Vaccines work by introducing a weakened or similar version of the virus (called an antigen) into the body, triggering an immune response that will fight off the real virus. So, it’s perfectly normal to experience some mild side effects as your body reacts to the vaccine.

Prolonged side effects after receiving the Covid-19 vaccine
Fever: Mild fevers below 38 degrees Celsius usually subside quickly and may last for 1-2 days. Higher fevers (> 38 degrees Celsius) should be monitored, and if the temperature doesn’t respond to common fever-reducing medications, consult a doctor or visit a healthcare facility.
Local Reactions: These include redness, swelling, hardness, or tenderness at the injection site and typically resolve within a few days to a week.
Joint Pain: This may resolve on its own, but in some cases, pain relievers may be necessary as advised by medical staff.
Acute Encephalitis or Meningitis: This rare complication involves sudden, severe symptoms such as seizures or altered consciousness and can last for one or more days. Seek immediate medical attention if these symptoms occur.
