Adverse reactions to vaccines
Disease description:
After receiving my first dose of the vaccine at the community clinic yesterday, I’ve been experiencing some abdominal discomfort, and I had mild diarrhea this afternoon. Could you please tell me what common adverse reactions are associated with this vaccine?

Hello,
It is possible to experience local reactions at the vaccination site, such as induration (hardening), redness, swelling, or even a palpable lump. These reactions typically occur on the day of vaccination or the following day and usually resolve gradually within 2–3 days. If local swelling is particularly severe, warm compresses may be applied. In most cases, no specific treatment is required.
Systemic reactions following vaccination may include fever, rash, nausea, vomiting, lethargy, irritability, and diarrhea.
We hope this information is helpful. Wishing you good health!
