NAPLEX (North American Pharmacist Licensure Examination) Practice Exam

What is the recommended administration timing between a live vaccine and an antibody product?

1. Vaccines than antibody product after 2 weeks

2. Antibody product than vaccines after 3 months

3. Simultaneous administration for PEP

4. Both B and C

The correct answer is: Both B and C

The recommended administration timing between a live vaccine and an antibody product is to first administer the antibody product, followed by the live vaccine 3 months later, or to administer both simultaneously for post-exposure prophylaxis (PEP). Option A is incorrect because it recommends administering the vaccine before the antibody product, which goes against the recommended order. Option B is only partially correct, as it recommends waiting 3 months but does not specify which should be administered first. Option C is incorrect because it does not specify a recommended timing for administration, and it also suggests simultaneous administration for PEP, which is not the only recommended timing for these products. Therefore, the best answer is Option D, which covers both recommended timing options.
