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 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:
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. Related Links
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.

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. 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. Back to top
