Vaccination Is Lifelong: Protection From Infancy Through Older Adulthood
When people think about immunizations, they often picture babies receiving routine vaccines or children preparing to return to school.
Vaccination, however, is not limited to childhood.
August is National Immunization Awareness Month, an annual observance that highlights the importance of vaccination for people of all ages.
Vaccination recommendations can continue throughout adolescence, adulthood, pregnancy, older adulthood, travel, and periods of increased health risk.
A Brief History of Vaccination
The history of vaccination stretches back centuries.
Before modern vaccines, some communities used a practice called variolation to expose people to material from smallpox sores in hopes of producing a less severe infection and future protection. Variolation carried serious risks, but it represented an early attempt to prevent deadly disease.
In 1796, English physician Edward Jenner demonstrated that exposure to cowpox could help protect against smallpox. His work contributed to the development of vaccination as we know it.
Vaccination gradually replaced variolation. Over time, scientists developed vaccines against many additional diseases.
One of the greatest public-health achievements in history was the eradication of smallpox. The World Health Organization began an intensified global eradication effort, and widespread vaccination ultimately stopped natural transmission of the disease.
Vaccines have since helped reduce illness, disability, hospitalization, and death caused by numerous infectious diseases.
Why Vaccination Matters
Vaccines help the immune system recognize and respond to certain infectious diseases.
Vaccination can:
- Reduce the likelihood of becoming seriously ill
- Lower the risk of certain complications
- Help protect people who cannot receive particular vaccines
- Reduce the spread of some diseases
- Protect individuals during vulnerable stages of life
- Help prevent outbreaks
No medical intervention is appropriate for every person in every circumstance. Recommendations may depend on age, medical history, allergies, pregnancy, immune status, previous vaccines, occupation, travel, and exposure risk.
That is why questions should be discussed with a trusted healthcare provider.
Infants and Young Children
Babies are particularly vulnerable to certain infections because their immune systems are still developing.
Routine childhood immunizations begin early to provide protection against diseases that can be severe or life-threatening. CDC schedules include vaccines beginning in infancy and continuing through childhood.
Parents should keep vaccination records and bring them to well-child appointments. Children with complex medical conditions may need an individualized vaccination plan developed with their healthcare team.
School-Aged Children and Teenagers
School vaccine requirements often bring attention to immunization, but protection, not paperwork, is the primary purpose.
As children grow, additional vaccines and booster doses may be recommended. Adolescence is also an important time to review records and catch up on missed doses.
Healthcare providers may discuss protection against diseases such as meningococcal disease, pertussis, human papillomavirus, influenza, and others based on current recommendations and individual circumstances.
Adults
Adults may assume that vaccines received during childhood provide all the protection they will ever need. Some protection can decrease over time, recommendations may change, and health conditions or life circumstances can create new risks.
Adults may need:
- Routine booster doses
- Seasonal vaccination
- Catch-up doses for vaccines they missed
- Vaccines related to pregnancy
- Vaccines required for work or travel
- Additional protection because of a chronic health condition
A medication list and vaccination record can help a healthcare provider determine what may be due.
Older Adults
The immune system changes with age, and some infections are more likely to cause severe complications in older adults.
Depending on age, health history, and current recommendations, a provider may discuss vaccines intended to reduce risks from illnesses such as influenza, pneumococcal disease, shingles, respiratory syncytial virus, tetanus, pertussis, and COVID-19.
Because recommendations can change, older adults and their caregivers should review vaccination status regularly rather than relying on an old list.
Caregivers and Household Members
Caregivers work closely with people who may be more vulnerable to infection, including infants, older adults, and individuals with chronic or complex medical conditions.
Caregivers should ask their own healthcare providers whether their vaccinations are current. Protecting caregiver health can also help maintain continuity of care for the person who depends on them.
Household members may also have vaccination recommendations based on the health needs of someone living in the home.
Where to Find Accurate Guidance
Vaccine schedules are updated as evidence, disease patterns, and available products change. The CDC provides immunization schedules by age, but a qualified healthcare professional should help interpret them for each person.
Reliable information may also be available from:
- Primary care providers
- Pediatricians
- Pharmacists
- Local public-health departments
- State health departments
- Specialists managing chronic conditions
Bring questions to the appointment. It is appropriate to ask about benefits, risks, possible side effects, timing, and alternatives.
Supporting Health Across the Lifespan
Dakota Home Care serves infants, children, adults, and seniors with a wide range of needs.
Our nurses and caregivers understand that protecting health may involve coordinating appointments, following individualized care plans, observing for changes in condition, supporting safe routines, and maintaining clear communication with families and healthcare providers.
National Immunization Awareness Month is an opportunity for every household, not only families with school-aged children, to review records and ask what protection may be recommended.
Check, Ask, and Stay Informed
This August:
- Locate your vaccination records.
- Review the records of children or adults in your care.
- Write down questions.
- Speak with a trusted healthcare provider.
- Follow an individualized recommendation based on current guidance.
Immunization is a lifelong health topic. Staying informed can help protect individuals, families, caregivers, and communities.
