In its April 4 weekly update, CDC reports 607 confirmed measles cases in 2025, with 93% of the cases associated with six outbreaks. Twenty-one states, pictured below, have reported at least one case this year. Most reported cases (481 of 607, 79%) have been reported by the Texas Department of State Health Services. On April 6, media outlets reported that an 8-year-old unvaccinated girl died of measles on April 3 at a Lubbock, Texas, hospital.
A map of 2025 measles cases, as of April 3, is shown below.
Vaccination is the only way to prevent measles: one dose protects about 93% of recipients and a second dose increases the likelihood of protection to 97% or higher. Two doses of MMR are recommended for all children and for adults who lack evidence of immunity and are at increased risk of exposure (such as healthcare professionals and international travelers born in 1957 or more recently) to protect against measles, mumps, and rubella. A single dose of MMR is recommended for previously unvaccinated adults born in 1957 or more recently who lack evidence of immunity and who are not at increased risk of exposure. With the exception of stem cell transplant recipients, people with two documented doses of live measles-containing vaccine administered on or after the first birthday do not need additional MMR doses or blood tests to evaluate measles immunity.
Children routinely receive their first dose of MMR at age 12–15 months and a second dose at 4–6 years, although the second dose may be administered as early as 4 weeks after the first dose. Infants who live in areas experiencing an outbreak or who travel internationally may receive a dose of MMR as early as age 6 months but will still need two doses after their first birthday for full protection. Families should follow state or local public health guidance concerning administration of early doses.

The 2023 ACIP recommendation for nirsevimab (Beyfortus, Sanofi), the RSV preventive antibody for all infants and high-risk toddlers, aligns the recommended timing of Beyfortus administration with the seasonality of RSV infection, which varies across the United States. In most of the “lower 48” states, Beyfortus use should begin October 1 and end March 31. Clinics in these areas with remaining Beyfortus inventory should refrigerate it under proper storage conditions until its recommended use resumes this fall.
Alaska and tropical climates have RSV circulation patterns that differ, and the recommended timing of Beyfortus administration differs. Locations with tropical climates include southern Florida, Hawaii, Guam, Puerto Rico, U.S. Virgin Islands, and U.S.-affiliated Pacific Islands. Providers in these jurisdictions should follow state or territorial guidance on timing of Beyfortus administration.

Immunize.org updated Spanish translations of 17 VISs to correspond with CDC's recently posted revisions, dated January 31, 2025. The revisions comply with a January 20, 2025, presidential executive order. Changes were limited to replacing the words “persons,” “person,” and “they” with the words "women," "woman," and "she" when referring to pregnancy or breastfeeding.
When given any VIS translation, the patient should also receive the current VIS in English. You Must Provide Patients with Vaccine Information Statements (VISs) – It’s Federal Law! offers additional tips on using VISs.
To locate all available VISs and clinical resources in a given language, visit our translations home page.Check the version dates of your inventory of VIS translations at regular intervals. Discard translations of previous versions as updated translations of current versions become available. Due to minimal content changes and uncertain schedules, Immunize.org elected not to update other VIS translations at this time.

National Infant Immunization Week (NIIW), April 21–28, highlights the importance of protecting infants from vaccine-preventable diseases and celebrates the achievements of immunization partners. Since 1994, hundreds of communities have joined together during NIIW to highlight the crucial role vaccination plays in protecting our children, communities, and public health.
CDC and the American Academy of Pediatrics recommend that children stay on track with their well-child appointments and routine vaccinations. Completing the recommended vaccinations by age 2 years is the best way to protect young children from 15 potentially life-threatening diseases. In light of the recent measles outbreaks, these messages are more important than ever.
CDC makes it simple to plan your NIIW activities by using their promotional materials including English and Spanish logos, sample social media content, social graphics, and key messages. Please share your posts using the hashtag #ivax2protect. Find more actionable strategies, resources, and data to support getting people of all ages on-schedule with their routine immunizations.

Confident healthcare provider recommendations for influenza vaccine are powerfully persuasive. This influenza season has been a tough one and it is not over yet. To help you maximize patient protection, Immunize.org, in collaboration with CSL Seqirus, updated the 65+ Flu Defense website.
This helpful site includes information, tools, and tips for communicating with adults age 65 and older about the scope and severity of influenza. Resources include:
- Influenza in Adults 65+: The Facts
- Influenza Vaccination: Questions Patients Aged 65 and Older Frequently Ask Their HCP
- The Importance of Preventing Influenza and COVID-19
Older adults are at increased risk of severe influenza, COVID-19, and RSV illness, including hospitalization and death, especially if they are not up to date on these vaccinations. A clinician recommendation is the most important reason why a patient will get vaccinated.
Check out the updated 65+ Flu Defense website to assist your ongoing efforts in protecting this vulnerable population.
