National Immunization Awareness Week: Vaccines Across the Lifespan

Article contributed by Audra Stewart-Gordon, Community Health and Communications Coordinator

National Immunization Awareness Week (NIAW) is observed each year in the last week of April across North America, in alignment with the World Health Organization’s World Immunization Week. It’s a time to highlight the critical role of vaccines in protecting health at every stage of life, not just during childhood.

Vaccines are among the most effective tools we have to prevent illness, reduce hospitalizations, and strengthen community health.

Why Immunization Matters—At Every Age

While childhood immunizations are well known, adults also need vaccines to protect against diseases like shingles, pneumonia, and influenza. Pregnant people, older adults, travelers, and those with chronic conditions may all require specific immunizations.

Vaccines recommended for adults and teens may include:

  • HPV – To prevent cancers caused by the human papillomavirus

  • Tdap – To protect against tetanus, diphtheria, and pertussis

  • Shingles (zoster) – For adults aged 50+

  • Pneumococcal vaccines – For those 65+ or with health conditions

  • Annual flu and COVID-19 boosters – To reduce severity and spread

The Maine CDC emphasizes that staying up to date on immunizations is essential to reduce the risk of serious disease and protect those who cannot be vaccinated due to age or health conditions (Maine CDC, 2024).

What’s at Risk Without Vaccinations?

When immunization rates fall, we see a resurgence of preventable diseases. Recent outbreaks of measles and pertussis in parts of the U.S. are reminders that vigilance and vaccination must continue across all age groups.

The Centers for Disease Control and Prevention (CDC) also notes that the COVID-19 pandemic disrupted routine healthcare, leading to lower vaccination rates for many adults. Reconnecting with providers and catching up on missed doses is vital for public health (CDC, 2023).

National Immunization Awareness Week - A Reminder to Take Action

  • Review your vaccination record and schedule any needed doses.

  • Talk to your provider about recommended vaccines for your age and lifestyle.

  • Encourage friends and family—especially seniors and at-risk individuals—to get vaccinated.

  • Support community outreach to make vaccines more accessible and equitable.

Immunization Is a Shared Responsibility

Vaccination protects individuals, families, and entire communities. When more people are immunized, fewer people get sick—and fewer lives are lost.

Let National Immunization Awareness Week serve as a reminder that good health is built on prevention. Vaccines are one of the easiest, safest, and most effective ways to invest in lifelong wellness.
