When most individuals think about vaccines, they imagine doctor visits in childhood, some crying, and possibly a few bright band-aids. But here’s the reality: vaccines aren’t solely a childhood milestone—vaccines are a lifelong means of maintaining your immune system healthy and your body safe.

As we age, our vaccination requirements change right along with us. Our work, our travel schedules, our medical conditions, and even our lifestyle choices all impact the type of protection we require. Keeping current on your vaccines is one of the easiest, most intelligent things you can do—not only for yourself, but for others around you, as well.
On the Front Lines: Vaccines for Healthcare Workers
If you’re employed in the healthcare industry, you’re not only caring for patients—you’re also one of the first lines of defense against the transmission of infectious diseases. Because of this, the CDC advises all healthcare workers, from physicians and nurses to laboratory technicians and hospital volunteers, to be current on crucial vaccines. These include:
- Influenza (yearly)
- Hepatitis B
- Measles, mumps, and rubella (MMR)
- Varicella (chickenpox)
- Tetanus, diphtheria, and pertussis (Tdap)
- COVID-19
Meningococcal (in some environments)
It’s not only about your safety—it’s about safeguarding patients who might be particularly at risk. In most instances, employers are legally obligated to offer workers at risk of exposure vaccines such as hepatitis B.
Traveling Overseas? Your Vaccine Passport Counts
Whether you’re going on safari, backpacking in Asia, or seeing relatives abroad, foreign travel can put you at risk for experiencing rare or non-existent diseases back home. See the CDC’s travel health pages before you leave and consult with a travel medicine expert at least 4 to 6 weeks before departure.
Certain places will require or suggest special vaccines, including:
- Yellow fever
- Japanese encephalitis
- Hepatitis A and B
- Typhoid
- Rabies
And don’t overlook the basics—being current on MMR, Tdap, and polio is just as important abroad as it is here at home.
Chronic Conditions Change the Game
If you’re living with a chronic health condition like diabetes, heart disease, lung disease (including asthma or COPD), or kidney or liver disease, your immune system may not be as strong at fighting off infections. That means certain vaccines become even more important.
- Diabetes or heart disease need to be vaccinated against pneumococcal disease.
- Individuals with liver disease need to be vaccinated with the hepatitis A and B vaccines.
- Individuals with HIV or other immune-compromising illnesses might require other vaccines based on their immune status.
- Pregnant women need to have the Tdap vaccine during pregnancy for each birth to protect their new baby from whooping cough, in addition to flu and COVID-19 vaccines.
Lifestyle and Life Circumstances Matter Too
Your circumstances and personal habits may also influence your vaccine requirements. For instance:
- Smokers are more susceptible to pneumococcal disease.
- Individuals who inject drugs or are homeless might require hepatitis A and B vaccines.
- Men who have sex with men might also find some additional vaccines helpful.
- Expecting to adopt internationally? You and your new baby might need to receive routine or country-specific vaccines.
Keeping Your Protection Up to Date
Vaccines aren’t a one-and-done deal—they’re an ongoing component of maintaining good health as your life evolves. The best way to remain on track is to have an honest conversation with your healthcare provider. They’ll assist you in determining what vaccines you require based on your age, health, profession, travel destinations, and lifestyle. And if you’re planning a trip or big life event, give yourself some lead time—some vaccines take a few weeks to take full effect or require multiple doses.
A Simple Act of Self-Care with Big Benefits
Vaccines are one of the easiest, most effective ways to protect yourself and others from serious illness. Whether you’re caring for patients, exploring new places, managing a health condition, or just going about your daily routine, staying current on your immunizations is a powerful act of self-care and community responsibility.
So don’t delay. Call your doctor, get your records updated, and keep your immune system in top form for whatever life has in store for you.
