Why Immunisation Is Important in Grand Rapids, Michigan

Immunisation (vaccination) is one of the safest and most effective ways to protect yourself, your family, and your community from serious infectious diseases. In Grand Rapids and across West Michigan, vaccines help keep our schools, workplaces, and neighborhoods healthier—especially during long Michigan winters, when respiratory illnesses spread more easily.

When you follow recommended vaccination schedules, you are not only protecting your own household, but also helping safeguard vulnerable people in Kent County who cannot be vaccinated themselves.

How Vaccination Protects Grand Rapids Communities

Immunisation Saves Lives

Just a few generations ago, diseases like measles, polio, and whooping cough caused thousands of deaths and lifelong disabilities in children across the United States. Thanks to widespread vaccination programs that began in the 1960s and 1970s, it is now rare for anyone in the U.S.—including Grand Rapids residents—to die from these vaccine‑preventable diseases.

However, these illnesses have not disappeared. Outbreaks still occur in communities where vaccination rates drop. Maintaining strong immunisation coverage in Grand Rapids is essential to prevent these diseases from returning.

How Vaccines Work

All vaccines work in a similar way:

  • A vaccine introduces a harmless part of a germ (or a weakened/inactivated form) into your body.
  • Your immune system “practices” fighting this germ and builds antibodies.
  • Later, if you are exposed to the real infection, your immune system recognizes it and responds quickly.

In simple terms, vaccination is like being exposed to a disease without suffering the actual illness and its potentially serious complications.

After vaccination, if you do catch the infection, you are more likely to have a much milder case and avoid hospitalization. This is especially important in Grand Rapids, where local hospitals such as Corewell Health (formerly Spectrum Health) Butterworth Hospital, Trinity Health Grand Rapids, Metro Health – University of Michigan Health, and Mercy Health care for large numbers of patients each year with respiratory and infectious diseases.

Unlike unproven approaches (such as homeopathy), vaccines are rigorously tested in large clinical trials and continuously monitored to ensure they are safe and effective.

Protecting Those Who Cannot Be Immunised

Some people in Grand Rapids cannot receive certain vaccines, including:

  • Newborns and very young infants
  • People receiving chemotherapy or other immune‑suppressing treatments
  • People with specific severe allergies or rare medical conditions

These neighbors rely on the rest of us to keep vaccination rates high so diseases cannot spread easily. When you keep your family’s vaccines up to date, you are helping protect:

  • Babies in local neighborhoods from Eastown to Wyoming
  • Older adults in senior living communities
  • Patients with chronic illness being treated at Spectrum Health, Trinity Health, Metro Health, and other Grand Rapids clinics

Herd Immunity (Community Immunity) in Grand Rapids

When enough people in a community are vaccinated, it becomes very difficult for a disease to spread from person to person. This is called herd immunity or community immunity.

  • If about 95% of people are vaccinated against certain diseases (like measles), outbreaks are far less likely.
  • Herd immunity protects everyone, but especially those who cannot be vaccinated.

In Grand Rapids schools, childcare centers, churches, and workplaces, strong community immunity helps prevent disruptive and dangerous outbreaks of diseases such as:

  • Measles
  • Whooping cough (pertussis)
  • Chickenpox (varicella)
  • Influenza (flu)
  • COVID‑19

Because Grand Rapids residents travel frequently for work, school, and leisure—often through Gerald R. Ford International Airport—diseases can be brought in from other states or countries. High vaccination coverage in Kent County helps stop these infections from spreading locally.

Modern Outbreaks and Why Vaccination Still Matters

Many vaccine‑preventable diseases are now rare in Michigan, but they have not disappeared worldwide. Recent and ongoing concerns include:

Coronavirus (COVID‑19)

COVID‑19 led to significant illness and hospitalizations in West Michigan. Vaccines have:

  • Reduced the risk of severe disease, hospitalization, and death
  • Helped local hospitals like Corewell Health and Trinity Health Grand Rapids manage patient loads
  • Allowed schools, businesses, and churches in Grand Rapids to reopen more safely

Research continues to improve COVID‑19 vaccines and understand long‑term effects of the virus.

Flu (Influenza)

Seasonal flu is a recurring problem in Michigan, especially during cold, dry winters when people spend more time indoors. Every year:

  • New flu strains circulate
  • The flu shot is updated to match the expected strains
  • Local clinics and pharmacies across Grand Rapids offer flu vaccination, often starting in early fall

Annual flu vaccination is highly recommended for:

  • Young children
  • Older adults
  • Pregnant people
  • People with chronic conditions such as asthma, diabetes, or heart disease

Other Global Infectious Diseases

Diseases like Zika, Ebola, and HIV/AIDS remain major public health concerns globally:

  • HIV/AIDS: Around 38 million people worldwide live with HIV. There is still no cure, but modern treatments allow many to live long, healthy lives.
  • Zika and Ebola: These viruses have caused serious outbreaks in other parts of the world. There are currently no widely available vaccines for Zika or Ebola for general public use, but research is ongoing.

While these diseases are not common in Grand Rapids, international travel and global health trends mean local public health agencies, such as the Kent County Health Department and Grand Rapids Public Health, closely monitor them.

Immunisation Surveillance in the United States

To keep communities like Grand Rapids safe, governments and health agencies need accurate information about:

  • How many people are vaccinated
  • Which diseases are circulating
  • How well vaccines are working
  • Any side effects or safety concerns

This is called immunisation surveillance.

In the United States, the Centers for Disease Control and Prevention (CDC) and state health departments (including the Michigan Department of Health and Human Services) collect and analyze vaccine data. They:

  • Track vaccine‑preventable diseases
  • Monitor outbreaks
  • Review reports of possible side effects
  • Update vaccination recommendations and schedules

Vaccines continue to be monitored even after they are approved and widely used. If any rare or unexpected side effects are detected, recommendations are updated to keep the public safe.

How New Vaccines Are Developed and Monitored

Developing a new vaccine is a careful, multi‑step process:

  1. Research and discovery – Scientists identify how a germ causes disease and which parts of it could trigger immunity.
  2. Pre‑clinical testing – Early safety and immune response testing in the lab and in animals.
  3. Clinical trials (in people)
    • Phase 1: Small group, focuses on safety
    • Phase 2: Larger group, looks at dosing and immune response
    • Phase 3: Large group, confirms effectiveness and monitors for side effects
  4. Regulatory review and approval – Agencies like the FDA carefully review all data.
  5. Manufacturing and distribution – Vaccines are produced in large quantities and shipped to clinics, hospitals, and pharmacies.

Even after vaccines are in use, they are:

  • Continuously monitored through surveillance systems
  • Reviewed if any safety concerns arise
  • Updated when needed (for example, the flu vaccine each year)

In the United States, national and regional systems monitor “adverse events following immunisation” (possible side effects). This ensures vaccines used in Grand Rapids remain safe and effective.

Who Should Be Vaccinated in Grand Rapids?

For most people, the answer is almost everyone.

Some individuals with serious medical conditions (like certain immune disorders, or a history of severe allergic reactions to a vaccine ingredient) may not be able to receive specific vaccines. This decision should always be made in consultation with a healthcare professional.

Your doctor or nurse will recommend vaccines based on your HALO:

  • H – Health condition (chronic illnesses, pregnancy, immune status)
  • A – Age (infants, children, teens, adults, seniors)
  • L – Lifestyle (travel, sexual activity, smoking, living in group settings like dorms)
  • O – Occupation (healthcare, childcare, education, public‑facing jobs)

Vaccination Is Especially Important If You:

  • Are a newborn or young child (follow the recommended childhood vaccination schedule)
  • Have a newborn baby at home
  • Are pregnant or planning a pregnancy
  • Care for very young babies (parents, grandparents, babysitters, daycare workers)
  • Are an older adult, particularly over age 65
  • Have chronic medical conditions (such as asthma, diabetes, heart disease, COPD, kidney disease)
  • Work in healthcare, education, childcare, or public service in Grand Rapids
  • Live or work in congregate settings (dorms, shelters, long‑term care facilities)
  • Plan to travel outside the United States (consult a travel clinic or CDC travel website for recommended vaccines)

If you are unsure which vaccines you or your children need, talk with your Grand Rapids primary care provider, pediatrician, or local clinic.
