Why Adult Vaccination Matters
Most Americans associate vaccines with childhood schedules, but immunity is not a one-time achievement. Some vaccines wear off over time, others were never received during childhood, and certain ones are specifically designed for adults facing age-related health risks. The Centers for Disease Control and Prevention (CDC) publishes updated adult immunization schedules each year, reflecting current evidence on disease burden and vaccine effectiveness.
Skipping adult vaccines is one of the most common gaps in preventive care — often because people assume their childhood shots still protect them fully. In practice, the picture is more nuanced. This article outlines which vaccines most adults should discuss with their healthcare provider, organized by who typically needs them.

Vaccines Recommended for Most Adults
The following vaccines appear on the CDC's routine adult schedule and apply to a broad population of adults regardless of specific risk factors.
Influenza (Flu)
Annual flu vaccination is recommended for virtually all adults. Influenza viruses mutate each season, which is why the vaccine is reformulated yearly. Flu can cause serious complications, including pneumonia and hospitalization, particularly in older adults and those with chronic conditions.
Tdap / Td (Tetanus, Diphtheria, Pertussis)
Adults who did not receive Tdap as an adolescent should get one dose. After that, a Td booster every 10 years maintains protection against tetanus and diphtheria. Pertussis (whooping cough) protection is also important for adults who have close contact with infants.
COVID-19
Updated COVID-19 vaccines are recommended annually for most adults, following guidance from the CDC's Advisory Committee on Immunization Practices (ACIP). Recommendations may shift over time, so checking current CDC guidance is advised.
RSV
RSV vaccines are now recommended for adults aged 60 and older, and for pregnant individuals during a specific window of pregnancy. This is a newer addition to the adult schedule following FDA approvals in recent years.
Booster dose
An additional vaccine dose given after the initial series to restore or strengthen immunity that has declined over time. Boosters are recommended on varying schedules depending on the vaccine and individual risk factors.
Immunization schedule
A clinical framework, published by bodies such as the CDC, that recommends which vaccines should be given, at what ages, and in how many doses. Adult schedules are updated annually based on evolving evidence.
Waning immunity
The gradual decline in vaccine-induced protection over time. Some vaccines confer long-lasting or lifelong immunity; others, like flu and tetanus, require periodic boosters to maintain effectiveness.
ACIP
The Advisory Committee on Immunization Practices — a group of medical and public health experts that advises the CDC on immunization policy in the United States. Their recommendations form the basis of the official US vaccine schedule.
Post-herpetic neuralgia
A painful nerve condition that can persist for months or years after a shingles outbreak. It is one of the most common and debilitating complications of shingles, particularly in older adults.
Shared clinical decision-making
A collaborative process in which a patient and their healthcare provider weigh the benefits, risks, and personal circumstances of a medical intervention together. Some vaccine recommendations are categorized this way when individual factors significantly influence the benefit-risk calculation.
Vaccines for Specific Life Stages and Risk Groups
Beyond routine vaccines, certain adults need additional protection based on age, health status, occupation, or lifestyle. Understanding these categories — which align with the decade-by-decade preventive care framework — helps you have a more informed conversation with your provider.
~49%
US adults who received a flu vaccine in a recent season
According to CDC flu vaccination coverage surveys, roughly half of US adults receive an annual flu vaccine — leaving many unprotected.
1 in 3
Americans who will develop shingles in their lifetime
The CDC estimates approximately one in three people in the US will develop shingles at some point, with risk rising sharply after age 50.
>40,000
Annual US deaths linked to vaccine-preventable diseases
Public health researchers estimate that tens of thousands of US adults die each year from diseases that vaccines can prevent, underscoring the importance of adult immunization.
Shingles (Recombivax / Shingrix)
The recombinant zoster vaccine (Shingrix) is recommended for adults 50 and older in two doses. Shingles risk increases significantly with age; the vaccine substantially reduces the likelihood of developing shingles and post-herpetic neuralgia, a painful complication.
Pneumococcal Vaccines
Adults 65 and older, and certain younger adults with chronic health conditions, are advised to receive pneumococcal vaccination to protect against pneumonia, meningitis, and bloodstream infections caused by Streptococcus pneumoniae.
HPV (Human Papillomavirus)
HPV vaccination is recommended through age 26 for all adults not adequately vaccinated in adolescence. For adults ages 27–45, shared clinical decision-making with a provider is recommended, as benefits vary based on prior exposure and individual risk.
Hepatitis A and B
Adults who were not vaccinated as children, or who have specific risk factors (travel to certain regions, certain occupational exposures, chronic liver disease), should discuss hepatitis A and B vaccination with their provider. Combination vaccines are available.
Meningococcal Vaccines
College freshmen living in dormitories, military recruits, travelers to certain regions, and adults with specific immune conditions or no spleen are among those for whom meningococcal vaccines are recommended.
How to Check Your Immunization Status
Many adults have incomplete or missing vaccination records, especially those who changed providers, moved states, or received vaccines abroad. Here are practical steps to review your status:
- Request records from past providers: Your primary care physician or previous practices may have records on file.
- Check your state immunization registry: Most US states maintain Immunization Information Systems (IIS) where vaccine records may be stored.
- Review your childhood vaccine history: If you have documentation from childhood, share it with your current provider to identify any gaps.
- Ask your pharmacist: Many vaccines — including flu, Tdap, shingles, and others — can be administered and recorded at community pharmacies.
Your healthcare provider can cross-reference your history against current CDC recommendations and identify which vaccines you may still need. This conversation is an ideal component of an annual wellness visit.
Vaccine Recommendations Change Over Time
The CDC adult immunization schedule is reviewed and updated each year. New vaccines may be added, age thresholds may shift, and booster guidance can evolve as new evidence emerges. Always refer to the most current CDC schedule — available at cdc.gov/vaccines — and discuss your personal history with a healthcare provider rather than relying solely on older records or memory.
