Kate, a 24-year-old woman with asthma, needs a refill on her inhaler. For her complete vaccination coverage, which additional vaccine should she receive?

For a 24-year-old woman with asthma, the recommendation to receive the influenza vaccine is particularly important, especially during flu season. Individuals with asthma are at a higher risk of developing complications from influenza, such as exacerbations of their asthma or more severe respiratory illness. Vaccination against influenza can help protect them from these potential complications and is recommended annually.

The other vaccines, while important, do not address the immediate risk associated with flu in patients with asthma. The pneumococcal vaccines (PPSV23 and PCV13) are generally recommended for older adults or those with specific chronic conditions, but they do not specifically target the risks posed by influenza, which disproportionately affects individuals with respiratory conditions like asthma. The MMR vaccine is important for preventing measles, mumps, and rubella, but it is not specifically indicated for a patient with asthma in the context of needing an additional vaccine at this time. Thus, the influenza vaccine is the most relevant and necessary choice.
