Adult Vaccination: Vaccines Are Not Just for Children

 

You completed your childhood vaccinations. So… are you done with vaccines for life?

Not quite.

 

Many adults think vaccination ends when childhood ends.

But our immunity can change with age, certain vaccines need boosters, and some infections become more serious in adults—especially older adults, pregnant women, people with chronic illnesses, healthcare workers, and those with weakened immunity.

 

Vaccination is therefore not only a childhood responsibility. It is part of lifelong preventive healthcare.

 

The Indian Academy of Pediatrics maintains updated immunization resources, including its Purple Book of Immunization 2025, while India's national immunization programme primarily focuses on childhood and selected groups. Adult vaccination decisions therefore often need an individualized assessment.

 

A simple example

Imagine a 42-year-old woman who regularly checks her blood pressure, thyroid, blood sugar and cholesterol.

She eats well. She exercises. She gets her annual health check-up.

But when asked:

“When was your last tetanus-containing vaccine?”

She says:

“I don't remember. Aren't vaccines only for children?”

This is a common situation.

Preventive healthcare is not only about detecting disease early. It is also about preventing disease before it happens.

 

Which vaccines may adults need?

There isn't one identical vaccination schedule for every adult.

Your vaccination needs may depend on:

Age

Previous vaccination history

Pregnancy

Occupation

Travel

Chronic medical conditions

Immunocompromised status

Previous infection

Lifestyle and exposure risks

Whether childhood vaccinations were completed.

 

Adult vaccination schedule:

 

 

Some vaccines commonly considered in adults include:

1. Tetanus, diphtheria and pertussis

Adults may need protection against tetanus and diphtheria, with pertussis-containing vaccination considered in appropriate situations.

A tetanus-containing vaccine becomes particularly relevant when vaccination history is incomplete or after certain wounds, depending on the individual's vaccination status and wound characteristics.

Don't wait for an injury to discover that your vaccination history is unknown.

2. Influenza vaccine

Influenza is often dismissed as “just flu.”

But influenza can cause significant illness, particularly in older adults and people with underlying heart, lung, metabolic or immune conditions.

Annual influenza vaccination may be recommended depending on age, health status, occupation and risk factors.

Think of it as part of seasonal preventive care, rather than something you take only after getting sick.

3. Hepatitis B vaccine

Hepatitis B can cause chronic liver disease, cirrhosis and liver cancer.

Adults who were not vaccinated previously may benefit from vaccination depending on their risk and medical circumstances.

It is particularly relevant for people with occupational exposure to blood or body fluids, certain healthcare workers, people with specific medical conditions or exposure risks, and others identified by their clinician.

A vaccine today can help prevent a liver problem years later.

4. HPV vaccine

HPV is associated with several cancers, including cervical cancer and cancers of the anus, penis, vulva, vagina and oropharynx.

HPV vaccination is most effective when given before exposure to HPV, but vaccination may still have a role in older adolescents and adults depending on age and individual circumstances.

This is an important reminder:

HPV vaccination is not only about preventing an infection—it is also about cancer prevention.

5. Pneumococcal vaccination

Pneumococcal infections can cause pneumonia, meningitis and bloodstream infections.

Risk increases with age and certain medical conditions.

Pneumococcal vaccination may therefore be considered particularly in older adults and people with specific chronic illnesses or immune compromise.

The exact vaccine and schedule depend on age, medical history and the vaccines already received.

6. Shingles vaccine

Many people know chickenpox.

Far fewer realize that the virus can remain dormant in the body and reactivate years later as shingles (herpes zoster).

Shingles can be extremely painful and may be followed by persistent nerve pain called post-herpetic neuralgia.

Vaccination against shingles is particularly relevant as people get older and for certain higher-risk individuals.

7. MMR and varicella

Some adults may not have adequate protection against:

Measles

Mumps

Rubella

Chickenpox

If there is no reliable evidence of previous vaccination or immunity, catch-up vaccination may be appropriate in selected adults.

However, live vaccines such as MMR and varicella require special consideration in pregnancy and certain immunocompromised states.

 

A practical age-wise approach:

 

18–49 years

Tdap/Td

Influenza annually

Hepatitis B if not vaccinated

HPV when appropriate

MMR/varicella if non-immune

COVID-19 according to current recommendations

Hepatitis A, typhoid, meningococcal, rabies, JE, yellow fever according to risk/travel

 

50–64 years

Annual influenza

Tdap/Td

Hepatitis B if indicated

Pneumococcal vaccination based on age/risk

Shingles vaccination

Other vaccines according to comorbidities/travel

 

≥65 years

Annual influenza

Pneumococcal vaccination

Shingles vaccination

Tdap/Td

Hepatitis B when indicated

RSV vaccination may be considered, particularly with increased risk

Other vaccines according to individual risk

 

What about pregnant women?

Pregnancy is a special stage of life where vaccination can protect both mother and baby.

Some vaccines are routinely recommended during pregnancy, while others should be avoided during pregnancy.

The appropriate vaccines and timing should therefore be discussed with the obstetrician.

Pregnancy is not a time to guess about vaccines.

What about people with diabetes, heart disease or other chronic illnesses?

This is where adult vaccination becomes especially important.

People with chronic diseases may have a higher risk of complications from certain infections.

For example:

Diabetes + infection → potentially greater risk of complications

Chronic lung disease + respiratory infection → potentially more severe illness

Immune suppression + certain infections → potentially significant consequences

Therefore, your vaccination plan should be considered alongside your medical history.

What if I am immunocompromised?

This requires individualized advice.

People who are immunocompromised because of disease or treatment may have different vaccination recommendations.

The type of vaccine, timing and number of doses can sometimes differ from those for healthy adults.

For example, vaccination may need to be planned around certain immunosuppressive treatments.

Don't simply follow the vaccination schedule of a healthy adult. Ask your treating doctor for a personalized plan.

Vaccination and cancer prevention

This is particularly important.

Some infections are linked to cancer.

HPV → several cancers

Hepatitis B → chronic liver disease and hepatocellular carcinoma

Therefore, vaccination can sometimes become part of a cancer-prevention strategy.

We often talk about screening for cancer.

But prevention can begin much earlier.

Prevention is not only finding cancer early.

Prevention also means reducing the chance of cancer developing in the first place.

“But I had all my childhood vaccines.”

That's excellent—but it doesn't necessarily mean you're protected against every vaccine-preventable infection throughout adulthood.

Some vaccines require:

Booster doses

Catch-up vaccination

Additional doses because the original series was incomplete

Vaccination because recommendations have changed

Special vaccination because your health circumstances have changed

And sometimes, you simply don't know what you received as a child.

That's okay.

Bring whatever vaccination records you have to your doctor and build your adult vaccination history from there.

Your Adult Vaccine Check-Up

At your next health check-up, ask:

“Am I up to date with my vaccines?”

Discuss:

☐ Tetanus/diphtheria/pertussis

☐ Influenza

☐ COVID-19, according to current recommendations

☐ Hepatitis B

☐ HPV

☐ Pneumococcal vaccination

☐ Shingles

☐ MMR

☐ Varicella

☐ Travel-related vaccines, if applicable

☐ Vaccines related to occupation or specific medical conditions

 

Not everyone needs every vaccine.

The right choice depends on your age, health, previous vaccinations and individual risk.

Don't Forget Your Vaccination Card

Create a simple Adult Vaccination Record.

Keep:

 

Vaccine | Date | Dose | Brand/batch if available | Next dose due

 

A vaccination record is especially useful when:

 

Changing doctors

Planning pregnancy

Starting a new job

Travelling internationally

Undergoing major surgery

Starting immunosuppressive treatment

Moving to another city or country

 

5 Vaccine Myths Adults Should Stop Believing

❌ Myth 1: “Vaccines are only for children.”

 

Fact: Vaccination can be relevant throughout life.

 

❌ Myth 2: “I'm healthy, so I don't need vaccines.”

 

Fact: Good health doesn't eliminate exposure to infections.

 

❌ Myth 3: “I don't remember my vaccination history, so I can't do anything.”

 

Fact: Your doctor can review available records and determine whether catch-up vaccination or other assessment is appropriate.

 

❌ Myth 4: “If I had the infection once, I never need the vaccine.”

 

Fact: This depends on the particular infection and vaccine.

 

❌ Myth 5: “Vaccines are needed only when travelling.”

 

Fact: Many vaccine-preventable infections occur in the community, not just during travel.

 

The Take-Home Message

 

We routinely check our:

 

Blood pressure.

Blood sugar.

Cholesterol.

Thyroid.

Vitamin levels.

 

Perhaps it's time to add one more question to our preventive health checklist:

 

“Are my vaccinations up to date?”

 

Because growing older should not mean becoming less protected.

 

Vaccination is not just a childhood appointment.

It is a lifelong conversation.

 

Protect today. Prevent tomorrow. Vaccinate for life.

 

The Indian Academy of Pediatrics provides an updated immunization resource library, and India's Ministry of Health & Family Welfare publishes the national immunization schedule and related guidance.

 

*Priority is not the same for every adult. The 2026 Indian Consensus Guidelines specifically stratify recommendations according to age, chronic disease, immunocompromised status, pregnancy, lifestyle and special situations.

 

A useful way to explain it to patients

 

Think of adult vaccines in three groups:

 

1. VITAL — don't miss when indicated

Td/Tdap, HPV, MMR, varicella and other vaccines where lack of immunity creates significant preventable risk.

 

2. ESSENTIAL — especially important for higher-risk adults

Pneumococcal, COVID-19 and shingles vaccination, with importance increasing with age and conditions such as diabetes, chronic heart/lung disease, kidney disease, malignancy or immunocompromised states.

 

3. DESIRABLE — useful according to individual circumstances

Influenza vaccination for lower-risk adults, hepatitis A, meningococcal, typhoid, travel-related vaccines and others depending on exposure and lifestyle.

 

One particularly important point: influenza should not be presented as “optional” for everyone. Indian public-health guidance recommends considering annual influenza vaccination routinely for adults ≥60 years, adults with comorbidities and pregnant women.

 

“Not every adult needs every vaccine—but every adult deserves a vaccine check-up.”

 

Check your BP. Check your sugar. Check your cholesterol. And don't forget to check your vaccination status.
