Why Adult Vaccines Matter More Than Most People Realize
When people think about vaccines, childhood immunization schedules usually come to mind. But immunity isn't a one-time gift — it can weaken over the years, and some diseases pose far greater risks to adults than to children. Vaccine-preventable illnesses send thousands of American adults to the hospital each year, many of whom assumed they were already protected.
The reality is that adult immunization is an active, ongoing process. Some shots need repeating on a schedule. Others are newly recommended based on age milestones or changes in personal health. And for travelers, healthcare workers, or people with chronic conditions, additional vaccines may apply. Preventive care for adults extends well beyond vaccines, but immunization is one of its most powerful and underutilized tools.
Vaccines and Herd Protection
When enough people in a community are vaccinated, diseases have fewer opportunities to spread — a phenomenon known as community immunity or herd immunity. This is especially important for protecting newborns, immunocompromised individuals, and others who cannot receive certain vaccines. Adult immunization contributes meaningfully to this collective protection.
Core Vaccines Recommended for Most Adults
The CDC's Advisory Committee on Immunization Practices identifies a core set of vaccines that most adults in the United States should receive, regardless of age or underlying health conditions:
- Influenza (flu): Recommended annually for all adults. Influenza can cause severe illness, hospitalization, and even death, particularly in older adults and those with chronic conditions.
- Tdap/Td (tetanus, diphtheria, pertussis): Adults who have never received Tdap should get one dose, followed by a Td booster every ten years. Pertussis (whooping cough) is particularly dangerous for infants, so vaccinated adults help shield those who can't yet be immunized.
- COVID-19: Updated COVID-19 vaccines are recommended for adults on a schedule determined by prior vaccination status and age. Guidelines are updated periodically; checking with a healthcare provider or the CDC website is advised.
- COVID-19 aside, hepatitis B is recommended for all adults under 60, and may be appropriate for those 60 and older based on individual risk discussion with a provider.

Annual U.S. adult deaths from vaccine-preventable diseases
According to estimates cited by the CDC and health advocacy organizations, tens of thousands of American adults die each year from diseases that vaccines can prevent.

Adults who will develop shingles in their lifetime
The CDC estimates that roughly one in three people in the United States will develop shingles at some point, with risk increasing significantly after age 50.

Adults under 65 who get an annual flu vaccine
CDC surveillance data consistently show that flu vaccination coverage among non-elderly adults lags significantly behind coverage among children and older adults.
Age-Based and Risk-Based Recommendations
Beyond the core vaccines, specific immunizations are recommended based on age and individual risk factors:
- Shingles (Zoster): Recommended for adults 50 and older. The recombinant shingles vaccine (Shingrix) is given in two doses and is highly effective at preventing shingles and its painful complication, postherpetic neuralgia.
- Pneumococcal vaccines: Recommended for adults 65 and older, and for younger adults with certain chronic conditions. These protect against pneumococcal disease, which can cause pneumonia, meningitis, and bloodstream infections.
- RSV vaccine: Recommended for adults 60 and older after discussion with a provider. RSV can cause serious lower respiratory illness in older adults.
- HPV vaccine: Recommended through age 26 for all adults who weren't vaccinated as adolescents. Some adults 27–45 may benefit after discussing risk with a provider.
People with chronic health conditions such as diabetes, heart disease, or compromised immune systems may have additional vaccine needs. Vaccines adults often overlook are a common gap in preventive care that a single conversation with a provider can close.
How to Take Action: Building Your Adult Immunization Plan
The most practical starting point is a conversation with a primary care provider. Many adults have incomplete or unavailable vaccination records, but providers can use clinical guidelines — and in some cases, blood tests to check immunity — to help determine what's needed.
Vaccines are also available at pharmacies, community health clinics, and public health departments. Many are covered by insurance as preventive services, including under Medicare and Medicaid plans. If cost or access is a concern, local health departments often provide low- or no-cost options.
Keep a Personal Vaccination Record
Ask your healthcare provider or pharmacy for a printed or digital record of each vaccine you receive, including the date and vaccine type. Many states also maintain immunization registries you can access. Having this record on hand makes it easier to know when boosters are due and to share your history with new providers.

Frequently Asked Questions
Most adults should receive an annual influenza vaccine, a Tdap or Td booster every ten years, and COVID-19 vaccines as updated. Additional vaccines — such as shingles, pneumococcal, or hepatitis — may be recommended depending on age, health conditions, and lifestyle factors. A healthcare provider can review your vaccination history and recommend what you're due for.
Yes. Immunity from childhood Tdap or DTP vaccines diminishes over time. Public health guidelines generally recommend a Tdap booster for adults who haven't had one, followed by a Td booster every ten years. Pregnant individuals are advised to receive Tdap during each pregnancy to protect newborns.
The CDC recommends the recombinant zoster vaccine (Shingrix) for adults 50 years and older, given in two doses. Shingles becomes significantly more common and more severe with age. Even people who have previously had shingles or received the older vaccine are generally advised to get Shingrix.
Many adult vaccines are covered under the Affordable Care Act as preventive services, meaning they may be available at no out-of-pocket cost on many insurance plans. Medicare also covers certain vaccines. Coverage details vary by plan, so it's worth confirming with your insurer or pharmacist.
Yes. Many routine adult vaccines — including flu, COVID-19, shingles, and Tdap — are administered at retail pharmacies as well as doctor's offices and public health clinics. Pharmacists are licensed to administer vaccines in all U.S. states, making access more convenient for most adults.
In most cases, yes. Health authorities confirm that receiving multiple vaccines in one visit is safe and effective. It can also save time and ensure you're protected sooner. Your healthcare provider can advise on the best sequencing for your specific health situation.
