Chickenpox – immunization

Chickenpox (Varicella) Immunization in Grand Rapids, Michigan

Chickenpox, also called varicella, is caused by the varicella‑zoster virus (VZV). It is a highly contagious infection that usually causes an itchy red rash with small fluid‑filled blisters, along with fever and fatigue.

While chickenpox is most common in children in Grand Rapids and across Michigan, teens and adults can get it too—and they tend to get sicker when they do.

In Grand Rapids, chickenpox vaccination is widely available through pediatricians, family doctors, local clinics, and public health programs, including:

• Corewell Health (formerly Spectrum Health) and Corewell Health primary care clinics
• Trinity Health Grand Rapids practices
• University of Michigan Health-West (formerly Metro Health) and Trinity Health Grand Rapids clinics
• Kent County Health Department and Grand Rapids Public Health services

Why Chickenpox Immunization Matters in Grand Rapids

Complications of Chickenpox

Most people recover fully from chickenpox, but it can sometimes cause serious complications, especially in:

• Adults
• Pregnant people
• Babies
• People with weakened immune systems (for example, from cancer treatment, long‑term steroid use, or certain chronic diseases)

Possible complications include:

• Skin infections (cellulitis) and scarring
• Pneumonia – more common and more serious in adults, can be life‑threatening
• Encephalitis – inflammation of the brain, sometimes severe
• Bleeding disorders – rare but potentially fatal
• Hospitalization and, rarely, death
• Shingles later in life – a painful blistering rash caused by reactivation of the same virus

In school‑age children in Grand Rapids, chickenpox can mean up to 2 weeks away from school, and parents may need to miss work to care for sick children.

Chickenpox and Michigan’s Seasons

In Michigan, chickenpox can spread easily during the school year when children are indoors together, especially in fall and winter when:

• Kids spend more time in close contact due to cold weather and snow
• Families gather indoors for holidays
• Immune systems can be stressed by other seasonal illnesses like flu and RSV

Vaccination helps protect children and adults in Grand Rapids year‑round and reduces outbreaks in schools, daycare centers, and workplaces.

How the Chickenpox Vaccine Works

Both the chickenpox (varicella) vaccine and the MMRV vaccine (measles, mumps, rubella, and varicella) contain a very weakened (live attenuated) form of the virus.

The vaccine:

• Does not cause full‑blown chickenpox
• Stimulates your immune system to make antibodies
• Helps your body recognize and fight the virus quickly if you are exposed later

This protection lowers your risk of getting chickenpox and reduces the chance of severe disease or complications.

Effectiveness of Chickenpox Immunization

Research shows:

• Two doses of the chickenpox vaccine in children provide stronger and longer‑lasting protection than one dose
• Vaccinated children who still get chickenpox (called breakthrough chickenpox) usually have:
  • Fewer spots
  • Lower fever
  • Faster recovery
  • Much lower risk of complications

Who Should Get the Chickenpox Vaccine in Grand Rapids?

Talk with your Grand Rapids healthcare provider (pediatrician, family doctor, or clinic) about chickenpox immunization if you or your child falls into any of these groups.

Children

• Routine childhood immunization:
  • Typically given as MMRV (measles, mumps, rubella, varicella) at the recommended ages per the CDC immunization schedule
• Children who have had chickenpox should still receive the combination MMRV vaccine, because it also protects against measles, mumps, and rubella.

Teens and Adults

People who benefit most from chickenpox vaccination include:

• Adults not immune to chickenpox, especially:
  • Parents of young children
  • Teachers and school staff
  • Childcare workers
  • Healthcare workers at Corewell Health, Trinity Health Grand Rapids, and University of Michigan Health-West, or other facilities
• Young children and teens who:
  • Have never had chickenpox
  • Have not been fully immunized
• People who live with someone with a weakened immune system, such as:
  • A family member on chemotherapy
  • Someone with an organ transplant
  • Someone with advanced HIV/AIDS

If you are unsure whether you’ve had chickenpox, your Grand Rapids provider can order a blood test to check your immunity.

For people 14 years and older, two doses of the chickenpox vaccine are recommended, given 1–2 months apart.

Chickenpox Vaccine and Pregnancy

Before Pregnancy

If you are planning to become pregnant:

• Ask your doctor or midwife to check your chickenpox immunity (blood test)
• If you are not immune and not pregnant, you may choose to receive the chickenpox vaccine before pregnancy
• You should avoid becoming pregnant for at least 1 month after each dose of varicella vaccine (your provider will give you exact guidance)

During Pregnancy

The chickenpox vaccine is not given during pregnancy.

If you are pregnant and not immune:

• Avoid close contact with anyone who has chickenpox or shingles
• Contact your doctor, midwife, or hospital immediately if you are exposed
• You may need special treatment to reduce the risk of severe disease and complications for you and your baby

Trinity Health Grand Rapids, Corewell Health/Butterworth Hospital, and other maternity services in the city can provide advice and care if exposure occurs.

Pre‑Immunization Checklist

Before you or your child receives the chickenpox vaccine in Grand Rapids, tell your doctor or nurse if you or your child:

• Are unwell with a fever over 38.5 °C (101.3 °F)
• Have allergies to any medicines, foods, or vaccine components
• Have ever had a serious reaction to any vaccine
• Have a disease or treatment that weakens the immune system, such as:

  • High‑dose steroids
  • Immunosuppressive medications
• Have received a blood or plasma transfusion or immunoglobulin within the last 3–11 months
• Are pregnant or planning to become pregnant soon
• Have received another vaccine within the last month or will receive another vaccine within 1 month of the chickenpox immunization

Your Grand Rapids immunization provider will help decide the safest timing and type of vaccine for you.

Side Effects of the Chickenpox Vaccine

The chickenpox vaccine is considered safe and effective, but like any medication, it can cause side effects.

Common Mild Side Effects

These usually occur in the first few days after vaccination and go away on their own:

• Pain, redness, or swelling at the injection site
• A small lump at the injection site that may last several weeks (no treatment needed)
• Mild fever
• Mild rash that looks like chickenpox near the injection site or elsewhere on the body
• Tiredness or fussiness in young children

A mild chickenpox‑like rash can occur 5 to 26 days after immunization.

Managing Fever After Immunization

If you or your child develops a fever after the vaccine:

• Drink extra fluids
• Do not overdress – use light clothing and bedding
• You may use paracetamol (acetaminophen) if needed:
  • Always check the label for the correct dose
  • Ask your pharmacist or pediatrician for dosing advice, especially for children
  • Routine use of paracetamol when there is no fever is not recommended

Rare but Serious Side Effects

Rarely, more serious reactions can occur:

• Severe allergic reaction (anaphylaxis)

  • Symptoms may include trouble breathing, swelling of the face or throat, hives, or feeling faint
  • This is why you are usually asked to stay at the clinic for at least 15 minutes after vaccination

• Thrombocytopenia (low platelets causing abnormal bleeding) – very rare

If you notice unexpected, persistent, or severe symptoms after vaccination, seek medical care immediately.

When to Seek Medical Help in Grand Rapids

Seek help right away if:

• You or your child has difficulty breathing, swelling of the face or throat, or a widespread rash after the vaccine
