In July, the United States already hit 33-year annual high in confirmed measles cases with 1,288 across 38 states
As of July 8, CDC reported 1,288 confirmed measles cases ([link removed]) in 2025 in 38 states, including the first cases reported this year in Wyoming. Among confirmed cases of all ages, 13% were hospitalized. Among those younger than age 5 years, 21% were hospitalized.
CDC only requires reporting of laboratory-confirmed measles cases. Cases without laboratory testing for confirmation are not included in these numbers. Actual numbers of cases are, therefore, higher than confirmed case counts.
A map of 2025 measles cases ([link removed]) in the contiguous United States, as of July 9, from the Johns Hopkins International Vaccine Access Center ([link removed]), appears below. The U.S. Measles Tracker ([link removed]) website includes state and county-level data.
Immunize.org offers measles-related resources for the public on two of our affiliated websites:
* VaccineInformation.org: Measles ([link removed]) web page
* LetsGetRealAboutVaccines.org: Measles ([link removed]) web page
LetsGetRealAboutVaccines.org gives plain language answers to questions such as, “Why does my child need to be vaccinated against measles?” and “What are the vaccines’ side effects?” See the “Getting Measles vs. Getting Vaccinated” table and downloadable fast facts sheet. LetsGetRealAboutVaccines.org also offers web links to partner sites for more information and social media assets.

National Immunization Awareness Month starts August 1. Promote protection with Voices for Vaccines' resources.
August is National Immunization Awareness Month ([link removed]) (NIAM). This annual observance highlights the importance of protecting people of all ages against vaccine-preventable diseases through on-time vaccination. This year, NIAM serves as a focal point to share trustworthy, credible information about the importance of staying up-to-date with routine immunizations.
Voices for Vaccines' (VFV) NIAM web page ([link removed]) includes key messages and sample social media content to grab the public's attention on immunizations. VFV encourages its partners to share these messages and resources using the hashtag #NIAM2025.
During NIAM, encourage your patients to schedule appointments to get up to date on annual exams and recommended vaccines. Research shows that healthcare providers remain the most trusted source of vaccine information for parents and patients.

FDA changes license for one of Moderna’s COVID-19 vaccines (Spikevax) to include children beginning at age 6 months at risk for severe COVID-19 disease
On June 25, FDA changed the license for one of Moderna’s two 2025–2026 formulation COVID-19 vaccines (Spikevax ([link removed]) ). Spikevax is now licensed for use in people with one or more high risk conditions for serious COVID-19 disease at age 6 months through 64 years. It remains licensed for use in all people age 65 years and older. Previously, children younger than age 12 years received Spikevax under the terms of emergency use authorization (EUA).
In fall 2025, Moderna also will offer a new formulation of mRNA COVID-19 vaccine with the tradename mNexspike. The mNexspike product is licensed for use in children and adults age 12 years through 64 years who are at increased risk of severe COVID-19 disease and for use in all adults age 65 years or older. This product is not licensed or authorized for use in children younger than age 12 years. See themNexspike labeling ([link removed]) for additional information.

“Lack of Evidence for Vaccine-Associated Enhanced Disease from COVID-19 Vaccines Among Adults in the Vaccine Safety Datalink,” published in Pharmacoepidemiology & Drug Safety, wins journal award for excellence
In its August 2024 issue, Pharmacoepidemiology & Drug Safety published Lack of Evidence for Vaccine-Associated Enhanced Disease from COVID-19 Vaccines Among Adults in the Vaccine Safety Datalink ([link removed]). This article won the 2024 Ronald D. Mann Best Paper Award given annually to this journal’s best paper. The prize is cosponsored by the publisher, John Wiley & Sons, Ltd., and by the International Society for Pharmacoepidemiology. An excerpt from the abstract appears below.
Methods: In this cross-sectional study, we assessed COVID-19 severity as a proxy for VAED [vaccine-associated enhanced disease] among 400 adults hospitalized for COVID-19 from March through October 2021 at eight US healthcare systems. Primary outcomes were admission to an intensive care unit (ICU) and severe illness (score ≥6 on the World Health Organization [WHO] Clinical Progression Scale). We compared the risk of outcomes among those who had completed a COVID-19 vaccine primary series versus those who were unvaccinated. We incorporated inverse propensity weights for vaccination status in a doubly robust regression model to estimate the causal average treatment effect.
Results: The causal risk ratio in vaccinated versus unvaccinated was 0.36 . . . for ICU admission and 0.46 . . . for severe illness.
Conclusion: Among hospitalized patients, reduced disease severity in those vaccinated against COVID-19 supports the absence of VAED.
Lead author, Thomas G. Boyce, a pediatric infectious disease specialist at Marshfield Clinic, is a member of the Vaccine Safety Datalink team. Immunize.org is honored to acknowledge that Dr. Boyce has graciously donated the award honorarium to Immunize.org to continue our efforts to share information about vaccine safety.

World Health Organization updates position paper on herpes zoster (shingles) vaccines
The World Health Organization (WHO) published WHO Position Paper on Herpes Zoster Vaccines—July 2025 ([link removed]) in the July 4 issue of its Weekly Epidemiological Record. This position paper focuses on zoster vaccination and supersedes the 2014 vaccine position paper on varicella and zoster vaccines. It reviews the evidence on the recombinant zoster vaccine (Shingrix, GSK ([link removed])) and provides recommendations on its use. The paper contains off-label recommendations.
The following passage appears in the document:
Herpes zoster [HZ] vaccination should be considered in the context of a life-course approach to immunization. In moving towards this approach, consideration needs to be given to the establishment of vaccination programmes for older adults which contribute to healthy ageing. Structures and strategies put in place for COVID-19 vaccination may be leveraged to deliver HZ vaccines as part of primary care services. Vaccination programmes for older adults could further be used to administer other important vaccines for this age group – such as influenza, RSV and pneumococcal vaccines.
