Match the following vaccines with their correct route of administration:

Disease/Vaccine	Route
a. BCG	1. Oral
b. OPV	2. Intramuscular (IM)
c. Hib	3. Intradermal (ID)
d. Measles	4. Subcutaneous (SC)

Which of the following is the correct match?

1. A

   a-3, b-1, c-2, d-4

2. B

   a-1, b-3, c-4, d-2

3. C

   a-3, b-2, c-4, d-1

4. D

   a-4, b-1, c-3, d-2

Explanation

• BCG (Bacillus Calmette-Guérin) vaccine is administered via the Intradermal (ID) route, which corresponds to match a-3.
• OPV (Oral Polio Vaccine) is given orally, corresponding to match b-1.
• Hib (Haemophilus influenzae type b) vaccine is given via the Intramuscular (IM) route, corresponding to match c-2.
• The Measles vaccine is administered Subcutaneously (SC), corresponding to match d-4.
• Therefore, the only option that correctly aligns all four vaccines with their standard administration routes is a-3, b-1, c-2, d-4.

Why Other Options Were Wrong

• Option B: This option incorrectly matches BCG with Oral, OPV with Intradermal, Hib with Subcutaneous, and Measles with Intramuscular routes. All pairings are incorrect.
• Option C: This option correctly matches BCG (a-3) but incorrectly pairs OPV with Intramuscular, Hib with Subcutaneous, and Measles with Oral routes.
• Option D: This option correctly matches OPV (b-1) but incorrectly pairs BCG with Subcutaneous, Hib with Intradermal, and Measles with Intramuscular routes.

Clinical Relevance

• Nursing practice connection: Knowing Vaccine Administration Routes helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
• Administering a vaccine via the wrong route can lead to reduced efficacy or an increased risk of local or systemic adverse reactions. For example, giving BCG subcutaneously instead of intradermally can cause a severe local reaction or abscess.
• Nurses must be thoroughly familiar with the National Immunization Schedule (NIS) of India, which specifies the correct vaccine, dose, route, and site for each age group to ensure patient safety and public health.
• What if? If a live vaccine like Measles (SC) were accidentally administered intramuscularly, it would likely still be effective, but it could cause more local pain and irritation as the formulation is designed for subcutaneous tissue.

How to Approach the Question

• This is a matching question. The goal is to pair each item in the first column (vaccine) with the correct item in the second column (route).
• First, recall the standard administration route for each vaccine individually. Start with the most distinct ones.
• BCG is famously given intradermally, creating a characteristic scar. So, 'a' must match '3'.
• OPV stands for Oral Polio Vaccine, making its route obvious. So, 'b' must match '1'.
• With 'a-3' and 'b-1' established, scan the options to see which one begins with this combination.
• Only the first option (a-3, b-1, c-2, d-4) matches these first two correct pairs. To be certain, verify the remaining pairs: c-2 (Hib-IM) and d-4 (Measles-SC), which are also correct.
