The 'T' series test for tetanus toxoid is used to assess immunity. How many doses of TT constitute the primary immunization series for a pregnant woman who has never been vaccinated before?
- A 1 dose
- B 2 doses given 4 weeks apart, with the second dose at least 2 weeks before delivery ✓
- C 3 doses at 0, 1, and 6 months
- D 5 doses over 1 year
Correct answer: B. 2 doses given 4 weeks apart, with the second dose at least 2 weeks before delivery
Explanation
For a pregnant woman with no prior TT immunization, two doses are given 4 weeks apart, with the second dose at least 2 weeks before delivery to ensure adequate transplacental antibody transfer. One dose gives no protection. The three-dose schedule is for long-term primary immunization of children and adults, not for pregnancy protection.
