CDC posts 2024–25 COVID-19 mRNA vaccine standing orders templates and at-a-glance resources. Immunize.org updates “Checklist of Current Versions of U.S. COVID-19 Vaccination Guidance and Clinic Support Tools.”

CDC posted highly anticipated new 2024–25 COVID-19 mRNA vaccine resources at its U.S. COVID-19 Vaccine Product Information main page. This page links to standing orders templates for Pfizer-BioNTech and Moderna mRNA vaccines (each vaccine has one template for young children and a separate one for people age 5 years and older). It also links to at-a-glance summaries for the two mRNA vaccines. Corresponding resources for the 2024–25 Novavax COVID-19 vaccine are coming soon.

Immunize.org reviews its Checklist of Current Versions of U.S. COVID-19 Vaccination Guidance and Clinic Support Tools at least monthly, prominently indicating when it was last revised. Due to the high priority of these updated CDC resources, Immunize.org revised the checklist for a second time in September.

All COVID-19 vaccine providers should regularly review this checklist. Download the latest documents and discard outdated versions.

Immunize.org updates “Standing Orders for Administering Respiratory Syncytial Virus Vaccine (RSV) to Adults Age 60 Years and Older”

Immunize.org updated its clinician resource, Standing Orders for Administering Respiratory Syncytial Virus Vaccine (RSV) to Adults Age 60 Years and Older to incorporate changes CDC recently made to its website for clinical considerations for RSV vaccination of adults age 60 through 74 at increased risk of severe disease. The changes to the website align the online guidance with the final, published ACIP recommendation. The following changes were made to the Immunize.org standing orders template:

  • The indication for vaccination based on residential setting was limited to nursing homes only. Previously, CDC’s website guidance included residents of nursing homes and other long-term care facilities (LTCFs).
  • Examples were added to illustrate the types of people age 60 through 74 without an ACIP-specified risk factor who may, nonetheless, be judged by a clinician to be at increased risk for severe RSV disease
  • A note was added to indicate ACIP’s recommendation that a vaccination provider should not deny a patient age 60 through 74 RSV vaccination because they lack documentation of a self-reported risk factor for severe RSV disease

Resume administration of nirsevimab preventive antibody (Beyfortus, Sanofi) to protect infants from RSV beginning October 1 in most jurisdictions

The 2023 ACIP recommendation for administration of nirsevimab (Beyfortus, Sanofi), the RSV preventive antibody product recommended as a one-time dose for infants younger than age 8 months born to mothers not effectively vaccinated against RSV during pregnancy, takes into account the seasonality of RSV activity. ACIP recommends that nirsevimab use should generally begin October 1 and end March 31 in jurisdictions with RSV seasonality typical of most of the contiguous United States (the “lower 48”).

Alaska and tropical climates may have RSV circulation patterns that differ from most of the contiguous United States. 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 public health guidance on timing of nirsevimab administration.



Healthcare providers should resume age-appropriate nirsevimab administration to eligible infants and high-risk toddlers as of October 1, unless otherwise recommended by your public health department. This includes:

  • Infants born from October through March, during their first week of life, if the mother was not effectively vaccinated with Abrysvo (Pfizer) RSV vaccine during pregnancy
  • Infants born April through September (younger than age 8 months) as they enter their first RSV season, if the mother was not effectively vaccinated with Abrysvo (Pfizer) RSV vaccine during pregnancy
  • Children age 8 through 19 months entering their second RSV season who are at increased risk of severe RSV disease (e.g., American Indian and Alaska Native children, children with chronic lung disease of prematurity, severe immunocompromise, cystic fibrosis with growth under 10th percentile), regardless of history of maternal vaccination

Providers are encouraged to send reminders to parents of high-risk infants age 8 through 19 months who need a dose this fall.

See Immunize.org’s standing orders template for the use of nirsevimab to review details of recommendations, including dosing, criteria for nirsevimab use in high-risk children during their second RSV season, and guidance for rare circumstances when nirsevimab is recommended for an infant younger than age 8 months despite maternal RSV vaccination.

Stay alert for measles cases

Given the 2024 increase in reported U.S. measles cases, Immunize.org reminds healthcare providers to watch for unvaccinated patients with febrile rash and other symptoms of measles (e.g., cough, runny nose, conjunctivitis). According to CDC's Measles Cases and Outbreaks web page:

  • As of September 19, 2024, a total of 262 measles cases were reported by 32 jurisdictions
  • Thirteen outbreaks (defined as 3 or more related cases) have been reported in 2024, and 70% of cases (184 of 262) are outbreak-associated. For comparison, 4 outbreaks were reported during 2023 and 49% of cases (29 of 59) were outbreak-associated.



On January 25, 2024, CDC issued a Clinician Outreach and Communication Activity (COCA) Now message titled Stay Alert for Measles Cases. A portion of the message outlining the recommendations for managing a suspected measles case is shown below.

  • Isolate: Do not allow patients with suspected measles to remain in the waiting room or other common areas of the healthcare facility; isolate [them], ideally in a single-patient airborne infection isolation room (AIIR) if available, or in a private room with a closed door until an AIIR is available. Healthcare providers should be adequately protected against measles and should adhere to standard and airborne precautions when evaluating suspect cases regardless of their vaccination status.
  • Notify: Immediately notify local or state health departments about any suspected case of measles to ensure rapid testing and investigation. Measles cases are reported by states to CDC through the National Notifiable Diseases Surveillance System (NNDSS) and can also be reported directly to CDC at measlesreport@cdc.gov.
  • Test: Follow CDC’s testing recommendations and collect either a nasopharyngeal swab or throat swab for reverse transcription polymerase chain reaction (RT-PCR), as well as a blood specimen for serology from all patients with clinical features compatible with measles. RT-PCR is available at CDC, at many state public health laboratories, and through the APHL/CDC Vaccine Preventable Disease Reference Centers.
  • Manage: In coordination with local or state health departments, provide appropriate measles post-exposure prophylaxis (PEP) to close contacts without evidence of immunity, either MMR or immunoglobulin. The choice of PEP is based on elapsed time from exposure or medical contraindications to vaccination.
  • Vaccinate: Make sure all your patients are up to date on measles vaccine, especially before international travel. People 6 months of age or older who will be traveling internationally should be protected against measles.

“Wastewater Surveillance for Influenza A Virus and H5 Subtype Concurrent with the Highly Pathogenic Avian Influenza A(H5N1) Virus Outbreak in Cattle and Poultry and Associated Human Cases—United States, May 12–July 13, 2024” published in MMWR

CDC published Wastewater Surveillance for Influenza A Virus and H5 Subtype Concurrent with the Highly Pathogenic Avian Influenza A(H5N1) Virus Outbreak in Cattle and Poultry and Associated Human Cases—United States, May 12–July 13, 2024 on September 19 in MMWR. A portion of the summary appears below.

Wastewater surveillance can detect influenza A virus and the H5 subtype, although current testing does not distinguish between human and animal sources. . . .

During May 12–July 13, 2024, high influenza A virus levels were detected in wastewater in four states, including three states with seasonal human influenza virus activity noted during this time. The H5 subtype was detected in wastewater in nine states; follow-up investigations in many of these states revealed likely animal-related sources, including those related to milk processing. . . .

Early work to interpret influenza A virus and H5 subtype detections in wastewater can help with public health preparedness and response for the upcoming respiratory illness season.

Recap: “Use of 2024–2025 COVID-19 Vaccines for Persons Aged ≥6 Months: Recommendations of the Advisory Committee on Immunization Practices — United States” published in MMWR Early Release

CDC published Use of 2024–2025 COVID-19 Vaccines for Persons Aged ≥6 Months: Recommendations of the Advisory Committee on Immunization Practices—United States in the September 10 issue of MMWR Early Release. The summary appears below.

The 2023–2024 COVID-19 vaccines provided protection against SARS-CoV-2 XBB-sublineage strains; however, these strains are no longer predominant in the United States. . . .

On June 27, 2024, the Advisory Committee on Immunization Practices recommended 2024–2025 COVID-19 vaccination with a Food and Drug Administration (FDA)–authorized or approved vaccine for all persons aged ≥6 months. In August 2024, the FDA approved and authorized the Omicron JN.1 lineage (JN.1 and KP.2), 2024–2025 COVID-19 vaccines by Moderna and Pfizer-BioNTech (KP.2 strain) and Novavax (JN.1 strain). . . .

The 2024–2025 COVID-19 vaccines are recommended for all persons aged ≥6 months to target currently circulating SARS-CoV-2 strains and provide additional protection against severe COVID-19–associated illness and death.

Recap: "Use of 21-Valent Pneumococcal Conjugate Vaccine among U.S. Adults: Recommendations of the Advisory Committee on Immunization Practices—United States, 2024" published in MMWR

CDC published Use of 21-Valent Pneumococcal Conjugate Vaccine among U.S. Adults: Recommendations of the Advisory Committee on Immunization Practices—United States, 2024 in the September 12 issue of MMWR. The summary appears below.

On June 27, 2024, the Advisory Committee on Immunization Practices recommended 21-valent PCV (PCV21) as an option for adults aged ≥19 years who are currently recommended to receive PCV15 or PCV20. PCV21 contains eight serotypes not included in other licensed vaccines. . . .

Adding PCV21 as an option in the current PCV recommendation is expected to prevent additional disease caused by pneumococcal serotypes unique to PCV21. Postlicensure monitoring of safety and public health impact of PCV use will guide future recommendations.




As illustrated in the table above, PCV21 (Capvaxive, Merck) is designed to protect against serotypes responsible for disease in adults. Unlike PCV15 (Vaxneuvance, Merck) and PCV20 (Prevnar 20, Pfizer), which are routinely recommended for children, PCV21 does not protect against certain serotypes historically responsible for a significant burden of disease in children that are not significant causes of disease in adults. For this reason, PCV21 is not licensed or recommended for use in children.

Recap: "Use of Haemophilus influenzae Type b–Containing Vaccines among American Indian and Alaska Native Infants: Updated Recommendations of the Advisory Committee on Immunization Practices―United States, 2024" published in MMWR

CDC published Use of Haemophilus influenzae Type b–Containing Vaccines among American Indian and Alaska Native Infants: Updated Recommendations of the Advisory Committee on Immunization Practices―United States, 2024 in the September 12 issue of MMWR. The summary appears below.

Haemophilus influenzae type b (Hib) vaccination with a monovalent Hib conjugate vaccine consisting of Hib capsular polysaccharide (polyribosylribitol phosphate [PRP]) conjugated to the outer membrane protein complex of Neisseria meningitidis serogroup B (PRP-OMP [PedvaxHIB]) has historically been preferred for American Indian and Alaska Native (AI/AN) infants to provide earlier protection in these populations at increased risk for invasive Hib disease. . . .

On June 26, 2024, the Advisory Committee on Immunization Practices recommended that hexavalent Vaxelis (diphtheria and tetanus toxoids and acellular pertussis, inactivated poliovirus, Hib conjugate, and hepatitis B vaccine [DTaP-IPV-Hib-HepB]) should be included with monovalent PRP-OMP in the preferential recommendation for AI/AN infants based on the Hib component. . . .

A primary Hib vaccination series consisting of monovalent PRP-OMP or DTaP-IPV-Hib-HepB is preferred for AI/AN infants.
