VaxInfo: Measles, Flu, COVID, RSV

Respiratory Virus Vaccines, 2025-2026 Season

Measles Vaccination & Exposure

Children who receive two doses of the measles, mumps, and rubella (MMR) vaccine spaced by at least 28 days and given after 12 months of age are considered fully vaccinated. They do not need additional doses of MMR vaccine and are in compliance with Colorado school immunization entry requirements. Families can check the Colorado Immunization Information System (CIIS) for vaccination records. Note that not all Colorado medical practices participate in CIIS.

Anyone exposed to measles who does not have immunity against the disease may be asked to quarantine. The MMR vaccine given within 72 hours of exposure can prevent or lessen the severity of the disease and is recommended for those who are not immune. Immune globulin (IG) is recommended within 6 days of exposure for those at risk of severe measles disease.

Frequently Asked Questions

Does my child need an MMR vaccine if they are under the age of 1? 

The routine childhood schedule is 1st dose at 12–15 months and 2nd dose at 4–6 years. There are no changes to statewide measles vaccination recommendations at this time. Children 12 months and older who have received their first MMR dose may receive the second dose at least 28 days later.

Does my child need to isolate? 

Children who are exposed to measles and do not have proof of vaccination or immunity may need to stay home from child care or school for 21 days after exposure, or until public health says it is safe for them to return.

How can I best protect my child from measles? 

The measles, mumps, and rubella (MMR) vaccine is the best way to prevent measles. Two doses of the vaccine offer about 97% protection. Parents should check their CIIS account to make sure their child is up to date on recommended vaccines. Vaccination helps protect people who cannot receive the vaccine, including babies younger than one year old and people with certain medical conditions.

What do I do if my child has symptoms of measles? 

If your child develops symptoms that could be measles, call your healthcare provider before going to a clinic, urgent care, or emergency room. Calling first helps prevent spreading the virus to others. If you have questions, call the Colorado Department of Public Health and Environment (CDPHE) measles information line at 720-653-3369.

Flu Vaccination

This year, trivalent flu vaccines are formulated to protect against three main groups of circulating seasonal influenza Type A and B viruses: an A(H1N1) virus, an A(H3N2) virus, and a B/Victoria lineage virus. With rare exceptions, all individuals aged 6 months and older should get a flu vaccine every season.

Making an Appointment

Flu vaccinations are available to current Boulder Medical Center patients. Appointments can be scheduled via MyChart or by calling your provider’s office. If you have an upcoming appointment, you can request your flu vaccination at that time, or attend one of our Saturday clinics.

Scheduling Family Members

If scheduling for family members, ensure you are in their MyChart account when booking the appointment. Each individual must have a separate appointment time. We cannot see multiple family members in one time slot.

COVID Vaccination

COVID vaccinations are available to current Boulder Medical Center patients aged 6 months and older.

Appointments

Appointments can be scheduled via MyChart or by calling your provider’s office. If you have an upcoming appointment, you can request your COVID vaccination at that time.

COVID Vaccination Insurance Coverage and Waivers

While most insurance carriers are expected to cover this year’s COVID-19 vaccination, coverage details may vary depending on the updated recommendations from the CDC’s vaccine advisory panel, anticipated in late 2025. Because of this, all patients receiving the vaccine will be asked to sign the BMC COVID Vaccination Waiver.

If you have Medicare, you will also be asked to sign the Advance Beneficiary Notice of Non-Coverage (ABN).

Additional information about COVID and the COVID vaccine is available on the CDC COVID vaccine webpage.

Respiratory Syncytial Virus (RSV) Vaccination

For Infants

This year, there are two options to protect your baby from RSV. Most babies only need one, not both. Discuss with your provider the best choice for you and your child.

• RSV Vaccine given during pregnancy
  • Protection is passed to the baby during pregnancy
  • Vaccine given to the parent at 32 – 36 weeks of pregnancy
  • Given September – January

• RSV Antibody given to the baby
  • Provides direct protection to the baby
  • Recommended for babies younger than eight months
  • Given October – January
  • Also recommended for some children aged 8-19 months if deemed still at risk for severe RSV

For Older Adults (Abrysvo)

• RSV can be dangerous for certain adults. CDC recommends the RSV vaccine for:
  • Individuals aged 75 years and older
  • Adults ages 50–74 who are at increased risk of severe RSV disease
