Measles outbreak: overview, thank you, and next steps

The measles outbreak in Minnesota, which occurred from May to Sept., has officially ended with 52 reported cases. However, measles remains a threat as new travel-related cases continue to emerge. There is the risk of a new outbreak each time an unvaccinated person returns to Minnesota with measles. In addition to the outbreak, Minnesota has had 10 travel-related cases of measles which led to the infection of eight additional people, resulting in a total of 70 cases of measles in 2024.

Vaccinate. Ask your patients about any upcoming travel plans. For children traveling internationally the MMR vaccine can be administered as early as 6 months of age. Be sure to review MMR vaccination status at every patient visit and encourage vaccination for those who are not yet immunized. 

  • Revisit the MMR conversation even if a parent has refused in the past. There is a perception among some parents that MMR vaccine is not needed because of low measles disease rates in the U.S. A recent outbreak of measles may cause some parents to rethink their decision to delay vaccination. Resources to support communication and outreach to patients is available on Measles (Rubeola) Basics.
  • The Client Follow-Up tool in the Minnesota Immunization Information Connection (MIIC) can support identifying and recalling children who are overdue. If you have interest in sending text message reminders to your patients, email health.miictexting@state.mn.us

Be alert for measles and report suspected cases at time of suspicion. Be especially suspicious of measles in unvaccinated people with recent travel who have a rash and fever. Information on reporting cases, specimen collection, and minimizing transmission are available on Measles Information for Health Professionals.


Thank you

We extend our gratitude to the dedicated clinics, hospitals, and local public health teams whose vigilant efforts in identifying and managing cases, as well as promoting immunization, played a key role in bringing the outbreak to a close.


Pertussis cases continue to increase

The Minnesota Department of Health (MDH) recently published Health Advisory: Pertussis Exceeds 2,000 in MN. Infants are at highest risk for morbidity and mortality from pertussis infection, but teenagers are experiencing the highest number of cases. This is in large part due to the known waning of immunity from the acellular pertussis component of Tdap vaccine. Take the following action steps to protect our most vulnerable and end the outbreak.

Vaccinate

  • Pregnant persons should receive Tdap during each pregnancy, regardless of prior Tdap history. It is typically given between 27-36 weeks' gestation but can be given safely at any time during a pregnancy when pertussis is in the community.
  • Infants and young children should receive DTaP at 2, 4, 6, and 15-18 months and 4-6 years of age.
  • 11–12-year-olds should receive Tdap as routinely recommended.
  • Adults should receive Tdap whenever Td is recommended, and all adults should have at least one dose of Tdap. It is recommended for routine immunization and wound management and provides additional pertussis protection.
  • Encourage all caregivers, adult household members and visitors who have not received Tdap vaccination to be vaccinated at least two weeks prior to contact with an infant.

Recall patients who are due or overdue for DTaP or Tdap using MIIC’s Client Follow-up feature due or overdue for DTaP and Tdap. Contact health.miichelp@state.mn.us if you need assistance. You can also participate in the MIIC Texting Program to send texts to patients overdue or recommended for DTaP, Tdap, and other routine immunizations. Contact health.miictexting@state.mn.us for more information.

Test and treat

Patients with cough illness should be tested for pertussis, even in mild cases, to prevent further transmission. Recognizing, testing, and treating early for pertussis is key to minimizing transmission.

  • Pertussis should be treated with antibiotics if diagnosed within the first 21 days of cough. Consider all family members when caring for a pertussis positive patient.
  • People symptomatic in the household should be recommended treatment, and People who are asymptomatic should be recommended post-exposure prophylaxis.
  • Exclude symptomatic children and adolescents from school, child care, and activities for the first 5 days of antibiotic treatment or 21 days of cough, whichever comes first.
  • Asymptomatic children and adolescents do not need to be excluded.

Pertussis is in the community. Share information about pertussis symptoms. For information to educate your patients visit:


Prevent cervical cancer with HPV vaccination

January is Cervical Cancer Awareness Month. Join MDH’s Immunization and Sage Cervical Cancer Screening programs in promoting on-time human papillomavirus (HPV) vaccination for adolescents 9-12 years of age and routine cervical cancer screening for adults. MDH will be promoting HPV vaccination for pre-teens through public social media posts, media ads, and more.

HPV infection can cause six types of cancer, including most cervical cancers. HPV vaccination can prevent more than 90% of these cancers. Recent data from MDH shows that Black, Asian, Hispanic, and American Indian Minnesotans are more likely to be diagnosed with cervical cancer than other races and Asian Minnesotans are more than two and a half times more likely to die from cervical cancer. Less than 60% of Minnesota 13-year-olds have started the HPV vaccine series and less than 30% have completed it. For more information on adolescent vaccination coverage data and gaps visit Adolescent Immunizations.

To participate, providers can provide a strong recommendation for HPV vaccination and start the conversation about HPV vaccine beginning at 9 years old.

  • Vaccinate as early as age 9 and promote on-time completion of HPV vaccine series by age 13. 
  • Share HPV cancer prevention messages with families and through social media and engage with MDH social media posts.

For more information on strategies for improving HPV vaccination rates in your clinic, visit For Health Care Providers Serving Adolescents.

Prepare for end of maternal RSV vaccination season on Jan. 31

ACIP recommends administering Abrysvo, an RSV vaccine, to pregnant people at 32-36 weeks' gestation from Sept. through Jan. This strategy allows for maternal antibody transfer to infants who are born when RSV activity is high. CDC provides key points for this recommendation:

  • Administration of maternal RSV vaccine starting in Sept. (at least one month before the start of the RSV season) and continuing through Jan. 31 (at least two months before the end of the RSV season) maximizes the cost-effectiveness and benefits of the vaccine.
  • RSV vaccine administered after Jan. 31 may not be covered by the pregnant person’s insurance.
  • All infants born between Oct. through March to pregnant persons who did not receive RSV vaccine should be offered nirsevimab, the RSV monoclonal antibody immunization.

All doses of maternal RSV vaccine should be documented in MIIC so information can be easily shared with birthing hospitals. Encourage pregnant people to access their immunization record through Docket, an application that provides a digital option to securely access immunization history in MIIC. For more information visit Docket and MIIC Immunization Records. RSV vaccine and nirsevimab documentation cards for patients are available on Respiratory Syncytial Virus (RSV) for Health Professionals.

For additional details refer to MMWR: Use of the Pfizer Respiratory Syncytial Virus Vaccine During Pregnancy for the Prevention of Respiratory Syncytial Virus–Associated Lower Respiratory Tract Disease in Infants: Recommendations of the Advisory Committee on Immunization Practices — United States, 2023.


Updated vaccine location finder for MnVFC and UUAV programs

MDH is pleased to announce the launch of an updated vaccine location finder to assist the public in finding facilities that participate in the Minnesota Vaccines for Children (MnVFC) and the Un- and Underinsured Adult Vaccine (UUAV) programs. The MnVFC program offers free or low-cost vaccines to children who are eligible and 18 years of age and younger. The UUAV program offers free or low-cost vaccines for eligible adults 19 years of age and older. You can view the vaccine location finder here on Vaccine Map.


Promote seasonal influenza vaccine among livestock workers

Avian influenza A (H5N1) virus, also known as bird flu, is causing outbreaks in wild birds, poultry, dairy cows, and other livestock. We are encouraging all those who work with livestock to receive the seasonal flu vaccine and urging employers of farm workers to encourage vaccination.

  • 61 human cases have been confirmed across the country as of Dec. 2024, the majority of whom had documented close contact with livestock.
  • The current risk to the general public is low, but those who work with or have recreational exposures to infected animals are at higher risk of infection. 
  • Currently there is no vaccine available for HPAI, but increasing seasonal flu vaccination among farm workers can prevent co-infections with H5N1 and seasonal flu, prevent severe illness, and help reduce the strain of the flu season on health care systems. It also can make it easier for public health agencies to better detect cases of H5 bird flu, should they occur.
  • Continue to offer influenza vaccine to all of your patients, and especially to patients who work on farms or own livestock.

Updated VISs translations of COVID-19 and RSV

Translated versions for the COVID-19 and RSV Vaccine Information Statements (VIS) are now available in 23 languages. These can be found on Immunize.org: VIS Translations Index.


Heplisav-B vaccine now an option for pregnant people

Heplisav-B is now included with Engerix-B, Recombivax HB, and Twinrix as a hepatitis B vaccination option for pregnant people 19-59 years of age. Additional research data presented to the Food and Drug Administration (FDA) on Sept. 11, showed no increased risk of major birth defects or miscarriage with use of Heplisav-B during pregnancy. The FDA: HEPLISAV-B package insert has been updated with this information. For details, refer to MMWR: Updated Recommendation for Universal Hepatitis B Vaccination in Adults Aged 19–59 Years — United States, 2024. MDH’s hepatitis B adult vaccine protocols have been updated and can be found on Vaccine Protocols: Hepatitis.


PreHevbrio discontinuation and guidance

PreHevbrio (hepatitis B vaccine, recombinant) was nationally recalled in Nov. due to bankruptcy of the company, VBI Vaccines Inc. and thus terminating operations. The company is notifying distributors, clients, and health care providers by direct mail to not use or further distribute and immediately destroy any existing vials. Further details can be found on VBI Vaccines Issues Voluntary Nationwide Recall of All PreHevbrio Vaccine Due to Discontinuation of Company Operations.

CDC has provided guidance on finishing the hepatitis B vaccine series for people who started with PreHevbrio on CDC: Hepatitis B Vaccine Administration and MDH vaccine protocols for hepatitis B have been updated on Vaccine Protocols: Hepatitis. If you have questions about hep B vaccination or PreHevbrio discontinuation email health.vaccineSME@state.mn.us.
