Which vaccines should adults review this season, and who may still need a catch-up dose?

Spring is a practical time for adults to take a fresh look at vaccine records. Adult vaccine needs are not one-size-fits-all, and the right next step depends on age, health conditions, and whether a person has already had certain doses.

That review matters now because the CDC updated adult pneumococcal and meningococcal guidance in February 2026, and respiratory illness activity is still part of the public-health picture in early May 2026.

The main adult vaccines to review

For many adults, the vaccines that most often come up in a record check are pneumococcal, RSV, meningococcal, flu, and COVID-19. The CDC’s adult immunization schedule is designed to help clinicians sort out which vaccines are routine, which are age-based, and which are recommended because of medical risk.

Pneumococcal vaccine: often age- or risk-based

The CDC says many adults should review pneumococcal vaccination based on age, certain medical conditions, and any pneumococcal vaccines they have already received. Adults age 50 and older, and adults ages 19 through 49 with certain risk conditions, may need a pneumococcal conjugate vaccine, with some people also needing a follow-up dose of PPSV23 depending on the product used and their history.

This is one of the clearest examples of why records matter. A clinician or pharmacist may need to know exactly which vaccines a person got before, not just whether they “had pneumonia shots.”

RSV vaccine: important for older adults and some younger adults at higher risk

The CDC recommends a single RSV vaccine dose for all adults ages 75 and older, and for adults ages 50 to 74 who are at increased risk of severe RSV illness. CDC also says RSV vaccine is not currently an annual vaccine, and adults who already received one dose should not get another at this time.

The best time to get an RSV vaccine is usually later in the year, before RSV starts spreading more widely, but adults can still use a spring review to confirm whether they are already covered or likely to need it later.

Meningococcal vaccine: usually for adults with specific risks

Adult meningococcal vaccination is generally risk-based. CDC recommends it for adults who are at increased risk, including some people with complement deficiencies, functional or anatomic asplenia, or certain immune-related medicine exposures. Travel, outbreaks, and some occupational or military situations can also matter.

Because recommendations can depend on the vaccine type and the reason a person is at risk, this is another area where a personalized review is more useful than guessing from age alone.

Flu and COVID-19: still part of the adult checklist

Influenza vaccine remains annual for adults, and the exact product or timing can vary by age and other factors. COVID-19 guidance also can differ by age and immune status, so the adult schedule is best used as a starting point, not the final word for every household.

CDC’s respiratory illness data channel says respiratory illness activity was very low as of April 17, 2026, with flu activity declining and COVID-19 low in most areas. Even with lower activity, vaccination review still matters because timing, age, and risk can affect whether someone should be protected before the next rise in cases.

What readers can do now

Start with three steps: find your vaccine record, note any chronic conditions or immune-related treatments, and ask a clinician or pharmacist for a personalized review. That is especially useful for adults who are older, pregnant, immunocompromised, living with chronic disease, or unsure whether they ever completed a series.

If you have fever, trouble breathing, chest pain, confusion, or other urgent symptoms after any illness, seek immediate medical care. For routine vaccine questions, a brief conversation now can help you avoid missed doses later.
