💉 Reaction to Tetanus Vaccine

Let’s understand this in a very simple way.

What is tetanus vaccine?
It is a vaccine given to prevent tetanus infection, which affects the nervous system and causes severe muscle spasms.

Can vaccines cause reactions?
Yes, vaccines can have some side effects, but most are mild and temporary.

✅ Correct Answer: (b) Brachial neuritis

What is brachial neuritis?
It is inflammation of the nerves in the shoulder/arm area, which can cause:

• Pain in the shoulder
• Weakness in the arm
• Difficulty in movement (rare cases)

This is a rare but known reaction associated with tetanus toxoid vaccine.

Why other options are not correct?

• (a) Febrile seizure → ❌ More common with other vaccines (like DPT), not specifically tetanus alone
• (c) Hypotonic → ❌ Seen in DPT (hypotonic-hyporesponsive episode), not tetanus toxoid alone
• (d) Encephalopathy → ❌ Very serious reaction, associated with pertussis component, not tetanus

Simple Exam Trick:
Tetanus vaccine → Think nerve-related rare effect → Brachial neuritis

📌 Note: Most people only experience mild pain or swelling at the injection site. Serious reactions are very rare.
