Suresh was bitten by a poisonous snake and was immediately treated with anti-venom human immunoglobulin and was saved. A year later, he was bitten by the same type of snake a second time. Predict his response to the venom from the second bite:
- 1There will be memory cells made after the first encounter, hence he will be more sensitive.
- 2There are residual cells or anti-venom antibodies that were involved in the original encounter, hence he will be protected.
- 3He will be equally sensitive as the first encounter because there would be no immunological memory of the first encounter.✓
- 4He will be fully protected from the effects of the poison the second time because he developed adaptive immunity after the first snake bite.
Correct answer
He will be equally sensitive as the first encounter because there would be no immunological memory of the first encounter.
