Vaccines Every Adult Should Have

Vaccines are a critical part of preventive care—not just for kids, but for adults, too. While many people associate vaccines with childhood, immunity can fade over time, and new risks emerge as we age. Keeping your immunizations up to date helps protect not only your health, but also the people around you.

From yearly flu shots to once-in-a-lifetime boosters, here are the essential vaccines every adult should know about—and when to get them.

Influenza (Flu) Vaccine – Every Year

The flu virus changes constantly, which is why a new flu vaccine is needed each year. Everyone over the age of six months is recommended to get an annual flu shot, but it’s especially important for:

• Adults over 50
• People with asthma, heart disease, or diabetes
• Pregnant individuals
• Healthcare workers and caregivers

Flu season generally runs from October to March, so getting vaccinated in early fall offers the best protection.

COVID-19 Vaccine – Updated Boosters

COVID-19 vaccines remain a key tool in protecting against serious illness and hospitalization. Updated boosters are recommended based on current variants and your individual risk profile.

Most adults should:

• Stay current with primary and booster doses
• Get updated vaccines annually or as directed based on age and health
• Consult a provider if immunocompromised or recently infected

Staying up to date with the latest COVID vaccine version ensures optimal protection throughout the year.

Tdap or Td Booster – Every 10 Years

The Tdap vaccine protects against tetanus, diphtheria, and pertussis (whooping cough). If you’ve never had a Tdap as an adult, get one dose, followed by a Td (tetanus and diphtheria) booster every 10 years.

Tdap is particularly important for:

• Adults who spend time around infants
• Healthcare providers
• Adults over 65 who never received it earlier

Tetanus bacteria can enter the body through cuts or wounds, so staying protected with timely boosters is vital.

Shingles (Herpes Zoster) Vaccine – Age 50+

The shingles vaccine is recommended for all adults aged 50 and older, regardless of whether they remember having chickenpox. The current preferred vaccine is a two-dose series, typically spaced a few months apart.

Shingles can cause a painful rash and nerve damage, with higher risks in older adults. The vaccine significantly reduces your chances of developing both shingles and postherpetic neuralgia.

Pneumococcal Vaccines – Age 65+ or High-Risk Adults

Pneumococcal vaccines protect against serious bacterial infections like pneumonia, bloodstream infections, and meningitis. There are two types—PCV15 and PPSV23—and recommendations depend on age, health conditions, and vaccine history.

Generally:

• Adults 65 and older should receive at least one pneumococcal vaccine
• Younger adults with chronic conditions (heart, lung, liver disease; diabetes; smoking history) may need it earlier
• Timing and combinations vary, so it’s best to review with your provider

These vaccines help prevent complications from respiratory illness and hospitalization in high-risk populations.

HPV Vaccine – Up to Age 45

The human papillomavirus (HPV) vaccine protects against the viruses most commonly linked to cervical, anal, and throat cancers, as well as genital warts. While it’s typically given in adolescence, adults can still benefit from it up to age 45.

Adults who didn’t receive the full series earlier should ask about:

• Catch-up doses (2 or 3 depending on age at first dose)
• Whether the vaccine still provides benefit based on age and sexual history
• Insurance coverage for adult doses

Even if already exposed to some strains, the vaccine offers protection against others.

Hepatitis A and B Vaccines – If Not Already Immune

Hepatitis A and B are viral infections that affect the liver and can lead to long-term complications. Many adults may not have received these as children unless they had specific risk factors or travel needs.

You may need the hepatitis vaccines if you:

• Work in healthcare, public safety, or correctional settings
• Have chronic liver disease
• Use intravenous drugs
• Travel to countries where hepatitis is common
• Have certain sexual risk factors

A simple blood test can check immunity if you’re unsure of your status.

MMR (Measles, Mumps, Rubella) – One or Two Adult Doses

Adults born after 1957 who haven’t received at least one MMR dose—or who lack immunity—may need vaccination. MMR is especially important for:

• College students and teachers
• Healthcare workers
• Travelers to areas with outbreaks

In some cases, two doses are recommended for full protection. Measles outbreaks still occur, making this vaccine relevant for public health.

Varicella (Chickenpox) Vaccine – If Not Immune

If you never had chickenpox and weren’t vaccinated as a child, you may need two doses of the varicella vaccine. This is less common, as most adults have natural immunity—but it’s still important to verify if you’re unsure.

Adults working in schools or healthcare may be especially encouraged to have confirmed immunity or vaccination.

Takeaway

Vaccines are one of the most effective tools in preventative healthcare. They not only reduce your risk of disease but also help protect your community by limiting the spread of contagious illness. By keeping a vaccination record and reviewing your needs annually with a provider, you can ensure lifelong protection against some of the most serious infections.
