Immunize​.org summarizes ACIP’s August 3 meeting recommending nirsevimab for RSV prevention in infants and inclusion in Vaccines for Children program

The Advisory Committee on Immunization Practices (ACIP) met on August 3 and recommended routine use of the monoclonal antibody product nirsevimab (trade name: Beyfortus, Sanofi) for the prevention of respiratory syncytial virus (RSV) lower respiratory tract infection (LRTI) in all infants younger than age 8 months during their first RSV season and in some children at high risk of severe disease during their second RSV season. Nirsevimab received FDA approval on July 17. Presentation slides are available online. Immediately after the meeting, CDC issued a media release announcing the director had adopted the ACIP recommendations, a step that initiates processes related to insurance coverage and implementation. Highlights of the meeting are provided below.
 
RSV Epidemiology

RSV is a common cause of respiratory illness and the leading cause of hospitalization of infants in the United States. Most (68%) infants are infected in the first year of life, and nearly all (97%) are infected by age 2 years. Of those infants with RSV infection, 2–3% require hospitalization, with an estimated 58,000–80,000 U.S. children younger than age 5 years hospitalized annually.
 
RSV infection typically causes mild upper respiratory symptoms, but can also cause bronchiolitis and pneumonia. Severe disease is most likely in very young infants and older infants born prematurely or with serious chronic diseases. Rates of severe disease are also 4–10 times greater in American Indian/Alaska Native (AI/AN) children than in the general population. Approximately 100–300 children younger than age 5 years die from RSV each year.
 
The RSV season typically occurs during October through March. The timing and severity of the season varies from year to year and between locations, particularly in areas outside the contiguous United States, such as Alaska, Hawaii, and overseas U.S. territories.
 
Nirsevimab Use

Nirsevimab is a long-acting monoclonal antibody product that provides passive immunization to the recipient for at least 150 days after administration. The pre-formed antibodies do not stimulate the immune system like an active immunization (vaccine). The rate of RSV-associated hospitalizations among recipients in clinical trials was 83% lower than among placebo recipients, and the rate of severe disease was 76% lower. Side effects were rare, with injection site reactions and rash reported in fewer than 1% of recipients.
 
Nirsevimab is administered intramuscularly (IM), with three dosing options based upon the child’s age and weight. Timing of nirsevimab administration is seasonal. Infants born during (or shortly before) the RSV season should be immunized within the first week of life (either before discharge from the delivery hospital or as an outpatient). Infants younger than 8 months of age who are born outside the season should receive nirsevimab shortly before, or early in, their first RSV season, and may be immunized when receiving other routine live or non-live vaccinations. Infants weighing less than 5 kg receive a 50 mg dose, and those weighing 5 or more kilograms receive a 100 mg dose.
 
ACIP separately recommended a 200 mg dose of nirsevimab (given as two 100 mg injections) for children age 8 through 19 months entering their second RSV season and at high risk of severe disease. Those recommended to receive nirsevimab in their second RSV season include those currently recommended by the American Academy of Pediatrics to receive palivizumab, a different monoclonal antibody that requires monthly administration. In addition, immunization was recommended for AI/AN children, who, as a population, are at high risk of hospitalization with RSV.
 
Nirsevimab is supplied in pre-filled 50 mg and 100 mg syringes that are stored at 2o–8oC, like refrigerated vaccines. The retail cost will be $495 per dose for 50 mg or 100 mg prefilled syringes. CDC will publish additional clinical considerations and professional educational materials in coming weeks.

 Unique Implementation Considerations

The ACIP decision to include nirsevimab in the Vaccines for Children (VFC) program will facilitate access for all infants, regardless of insurance status. However, some implementation challenges remain because the product is not a traditional vaccine. Some jurisdictions may have different scope of practice regulations related to who is allowed to administer it. Seasonal administration will require planning and training. Payment issues will need to be addressed to facilitate its use in birthing hospitals. There may be issues to resolve in electronic health record system documentation and reporting to state immunization information systems.

ACIP Vote
   
ACIP made two separate and unanimous votes to recommend nirsevimab for two groups:
  • Infants younger than age 8 months born during or entering their first RSV season should receive one dose (50 mg for infants weighing less than 5 kg, 100 mg for those 5 kg or more)
  • Children age 8 months through 19 months who are at increased risk of severe RSV disease and entering their second RSV season – one dose (200 mg) 
The Committee also unanimously approved including nirsevimab in the VFC program.

Future discussions

ACIP members noted that a maternal vaccination for RSV designed to protect newborns is being considered for licensure by FDA. If a maternal RSV vaccine is licensed and recommended, ACIP will revisit the nirsevimab recommendations and adjust them as necessary.
 
The next scheduled ACIP meeting will be held on October 25–27, although additional emergency meetings may be announced prior to that time. Information about past and future ACIP meetings may be found on the ACIP website.

New! Immunize​.org updates its summaries of 2023 state immunization requirements for childcare, school, and college entry, including new summary maps.

Childcare and school requirements for vaccination vary by state and are critical to making childcare facilities and schools a safe and healthy learning environment for everyone. In the spring of 2023, Immunize​.org surveyed all state immunization program managers to update its detailed data tables on state vaccine-specific requirements for childcare, school, and college students. Based on information provided or confirmed by immunization managers, Immunize​.org updated its State Requirements by Vaccine main page and each of its pages detailing vaccine-specific requirements by state for childcare, K-12, and post-secondary education settings. In addition, new and improved state maps were produced to visually represent vaccine-specific requirements and state policies related to exemptions. These maps are ideal for use in presentations by policymakers, healthcare professionals, and advocates. 



Below are links to each of the vaccine-specific requirement pages and the exemptions page:

August is National Immunization Awareness Month; promote vaccination with helpful resources for all ages

August is National Immunization Awareness Month (NIAM). This annual observance highlights the efforts to protect people of all ages against vaccine-preventable diseases through on-time vaccination. This year, NIAM serves as a focal point to get back on track with routine vaccines.

NIAM is a good time to remind healthcare providers that they are still the most trusted source of vaccine information for parents and patients. Encourage patients to schedule appointments to ensure they are up to date on annual exams and recommended vaccines.

CDC’s NIAM web page includes two toolkits, one for reaching healthcare professionals and the other for reaching parents and patients. Each includes key messages, sample social media content, and educational resources. CDC encourages its partners to share these messages and resources throughout August using the hashtag #ivax2protect.

“Vaccination Coverage among Adults in the United States, National Health Interview Survey, 2021” published by CDC

On July 19, CDC published Vaccination Coverage among Adults in the United States, National Health Interview Survey, 2021. The conclusion section appears below.

Coverage increased for influenza and herpes zoster vaccination in recent years. Disparities in vaccination coverage by race and ethnicity were seen for all vaccines assessed. Increasing the proportion of adults who receive recommended vaccines and ensuring equitable access to, and uptake of recommended vaccines is a high-priority public health issue.

“Measles Outbreak—Central Ohio, 2022–2023” published in MMWR

CDC published Measles Outbreak—Central Ohio, 2022–2023 on August 4 in MMWR. Our analysis of Notes from the Field is summarized below.

  • Although the United States has maintained measles elimination since 2000, measles outbreaks continue to occur in countries around the world. Thus, there is always a risk of measles importation that could affect undervaccinated communities.
  • In November 2022, two 2-year-old children were admitted to the same hospital in Ohio for suspected measles infection, so public health officials launched an investigation 
  • A total of 85 people in central Ohio tested positive for measles
  • This outbreak was characterized by young median patient age (1 year), low rates of MMR vaccination, and high rates of respiratory coinfection (e.g., respiratory syncytial virus [RSV]), with twice the hospitalization rate reported among previous U.S. measles cases
  • Two-dose MMR vaccination coverage among children entering kindergarten in Ohio during the 2021–22 school year (i.e., before the outbreak) was 5% lower than the national coverage estimate of 93%
  • Healthcare facilities, clinicians, and childcare centers serving undervaccinated populations should remain on high alert for measles and emphasize the importance of timely MMR vaccination

WHO releases message from Director of Immunization, Vaccines, and Biologicals on the release of country vaccination estimates 

On July 31, the World Health Organization (WHO) released Message by the Director of the Department of Immunization, Vaccines and Biologicals at WHO—July 2023. A portion of the article appears below. 

The WHO/UNICEF estimates of national immunization coverage (WUENIC) for 2022 were released on 18 July. . . .

The WUENIC findings are encouraging: some immunization services have begun to recover after the disruptions caused by COVID-19 – meaning that immunization services reached 4 million more children than in 2021. Despite this overall improvement, the recovery has been uneven across countries, across vaccines, and across age groups. Even with evidence of a recovery underway in 2022, more than 20 million children still missed out on one or more vaccines last year, and over 14 million missed out entirely. These numbers are higher than in 2019, the year before the pandemic hit. . . .  

Most concerningly is that as a group, low-income countries are not yet showing signs of immunization recovery. For these countries, measles vaccine coverage has continued to backslide in 2022, raising the alarm even further for immediate action. We must catch-up, restore, and strengthen all national immunization programs to ensure that all children, no matter where they are, have access to and receive the life-saving vaccines which are their right. 

The WUENIC-2022 release of country estimates coincided with the halfway mark for the Big Catch-Up, underscoring the need for sustained action to strive for catch-up, equitable recovery and strengthening for the remainder of the year and beyond.
