Which of the following is called internationally available cholera vaccine?

Appeared in: RIMS Nursing Officer - 2022

Explanation

  • Dukoral is an internationally licensed oral cholera vaccine, available in over 60 countries.
  • It is a killed whole-cell vaccine (WC-rBS) containing both biotypes and serotypes of Vibrio cholerae O1, supplemented with the recombinant B subunit of the cholera toxin.
  • It is one of the oral cholera vaccines prequalified by the World Health Organization (WHO) and is often recommended for travelers to endemic areas.

Why Other Options Were Wrong

  • Option B: Daptacel is a combination vaccine that protects against Diphtheria, Tetanus, and acellular Pertussis (DTaP). It offers no protection against cholera.
  • Option C: Vivotif is an oral, live attenuated vaccine used for the prevention of typhoid fever, which is caused by the bacterium Salmonella Typhi, not Vibrio cholerae.
  • Option D: Menactra is a quadrivalent conjugate vaccine that protects against four serogroups (A, C, Y, and W) of Neisseria meningitidis, the bacterium that causes meningococcal meningitis. It is unrelated to cholera.

  • Nurses play a vital role in travel medicine, advising patients on necessary vaccinations. Knowing the specific indications for vaccines like Dukoral is essential for providing accurate patient education.
  • Patient counseling for cholera vaccination must emphasize that it does not provide 100% protection and should be combined with preventive measures like hand hygiene and ensuring the safety of food and water.
  • Proper administration is critical for oral vaccines like Dukoral, which requires mixing with a specific buffer and avoiding food or drink for a period before and after ingestion to ensure efficacy.

  • First, identify the key terms in the question: 'internationally available' and 'cholera vaccine'.
  • Systematically evaluate each option to see if it matches the description of a cholera vaccine.

  • Eliminate the other options by identifying the distinct diseases they target: Daptacel (DTaP), Vivotif (Typhoid), and Menactra (Meningococcal disease).
  • Confirming that Dukoral is the only cholera vaccine among the options leads to the correct answer.
