Which immunization should be ensured for a daycare outbreak of chicken pox to protect immunocompromised children?

• A. Varicella
• B. MMR
• C. Hib
• D. DTaP

Answer: (A)

To protect immunocompromised children during a chickenpox outbreak, the key is to ensure immunity against varicella among those who can be vaccinated. Varicella vaccine helps prevent chickenpox and can also lessen how readily the virus spreads if exposure occurs. In a daycare, vaccinating susceptible staff and children creates herd protection, reducing the chance that an immunocompromised child is exposed to the virus, since they may not be able to receive the vaccine themselves or may be at higher risk for severe disease. The other vaccines—MMR, Hib, and DTaP—do not prevent varicella outbreaks, so they aren’t the focus in this scenario.
