Newly updated 65+ Flu Defense website offers resources for healthcare professionals serving older adults  

Confident recommendations for influenza vaccine from healthcare providers are powerfully persuasive. To assist you in maximizing protection for your patients, Immunize.org, in collaboration with CSL Seqirus, updated the 65+ Flu Defense website at www.influenza-defense.org.

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:

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 at www.influenza-defense.org to assist your ongoing efforts in protecting this vulnerable population.

CDC releases survey results on nirsevimab acceptance among pregnant people on the Weekly RSV Vaccination Dashboard  

On January 10, CDC released National Immunization Survey (NIS) data from the NIS-Adult COVID Module on the acceptance of nirsevimab among pregnant people. Among females age 18–49 years with a baby younger than 8 months of age interviewed during October 29–November 25, 2023:  

  • 20.6% reported they got nirsevimab for their infant
  • 26.9% reported they definitely will get nirsevimab for their baby
  • 47.3% probably will get nirsevimab for their baby or are unsure 
  • 5.2% probably or definitely will not get nirsevimab for their baby 
CDC will update estimates and release them monthly on CDC's Weekly RSV Vaccination Dashboard, RSVVaxView.

RSV activity remains elevated nationwide and is continuing to increase in many parts of the country.

To prevent severe RSV disease in infants, either Pfizer's RSV vaccine (Abrysvo) for pregnant people or nirsevimab (Beyfortus, Sanofi) for infants is recommended.
  • Maternal vaccination: seasonal administration of maternal RSV is only recommended through the end of January for most of the continental United States
  • Infant immunization: infants born to unvaccinated mothers during RSV season should receive nirsevimab through the end of March in most of the continental United States

January is Cervical Health Awareness Month; promote the importance of HPV vaccination 

January is Cervical Health Awareness Month, a great time to share the importance of human papillomavirus (HPV) vaccination. Almost all cervical cancer cases (99%) are linked to infection with high-risk HPV strains, a very common virus transmitted through intimate contact.

CDC recommends HPV vaccination for everyone 26 years old or younger, beginning as early as age 9. Adults age 27 through 45 years who are not already vaccinated may decide to get the HPV vaccine after speaking with their clinician.

Protect your patients from cervical cancer, and the many other HPV-related cancers affecting men and women, by recommending, promoting, and offering the HPV vaccine.

Review your COVID-19 resources with the latest Immunize.org “Checklist of Current Versions of U.S. COVID-19 Vaccination Guidance and Clinic Support Tools”  

Immunize.org reviews and updates the 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 at the top of the page. The January 9 checklist provides updated links to CDC's COVID-19 materials.

Several footnotes now highlight the different storage requirements for two presentations (glass or plastic) of Pfizer-BioNTech’s Comirnaty vaccine available in manufacturer-filled syringes (MFSs).

  • Glass MFSs must be stored at refrigerated temperatures (2º through 8ºC, 35º through 46ºF) and should NOT be frozen. Labels on individual glass syringes and their cartons prominently display a “DO NOT FREEZE” warning. 
  • Plastic MFSs are shipped and may be stored at ultracold temperatures (–90º through –60ºC, –130º through –76ºF)

Future CDC materials will indicate this difference in storage guidance.

All COVID-19 vaccine providers should review the checklist regularly and download the latest CDC schedule and standing order documents. Discard any outdated versions of cited documents. The checklist is posted on Immunize.org's Vaccines A–Z: COVID-19 main page to help practices stay up to date.

Influenza-like illness is high from coast to coast; encourage influenza, COVID-19, and RSV vaccination now

CDC’s Weekly U.S. Influenza Surveillance Report, FluView, provides a valuable picture of laboratory-confirmed influenza and influenza-like-illness (ILI) activity state by state. ILI activity is caused by a variety of respiratory illnesses, including three vaccine-preventable infections: influenza, COVID-19, and RSV.

Influenza Surveillance
For week 1, ending January 6, CDC’s Weekly U.S. Influenza Surveillance Report, FluView shows that 37 jurisdictions experienced high or very high activity. Nationwide, 5.7% of patient visits reported through the Outpatient Influenza-Like Illness Surveillance Network (ILINet) were due to respiratory illness that included fever plus a cough or sore throat (i.e., ILI). The national baseline is 2.5%. Thirteen pediatric influenza-associated deaths were reported this week, bringing the total to 40 pediatric deaths thus far during the 2023–24 season. Given the relatively low influenza, COVID-19, and RSV vaccination rates to date, millions more people remain unprotected, compared to last season.

Visit the CDC Respiratory Virus Hospitalization Surveillance Network (RESP-NET) for weekly reports of hospitalizations across the United States due to three vaccine-preventable seasonal respiratory viruses: COVID-19, influenza, and RSV. 

Influenza Vaccination Dashboard
CDC's Weekly Flu Vaccination Dashboard shows that as of December 30, an estimated 45% of adults have received an influenza vaccine, with state estimates ranging from 31% to 55%. Influenza vaccination among pregnant people is lagging behind where it was in December 2022. Only 36.2% of pregnant people were vaccinated against influenza by December 2023, compared to 39% last year, despite the growing body of evidence of safety and benefit for both mother and infant. It is critical to protect people now, as influenza activity is becoming widespread.

CDC recommends everyone age 6 months and older get annual influenza vaccination. Influenza and other vaccines (e.g., COVID-19 vaccine, RSV vaccine) may be given at the same visit, if indicated. Infants 6 months of age and older may receive influenza and COVID-19 vaccines at the same visit when they receive the RSV preventive antibody, nirsevimab.

Locate influenza and COVID-19 vaccines in your area by entering your zip code in the VaccineFinder on Vaccines.gov or Vacunas.gov. To be listed as a provider by VaccineFinder, see the information on this website.

“Effectiveness of Bivalent mRNA Vaccines in Preventing COVID-19-Related Thromboembolic Events among Medicare Enrollees Aged ≥65 Years and Those with End Stage Renal Disease―Unites States, September 2022–March 2023” published in MMWR 

CDC published Effectiveness of Bivalent mRNA Vaccines in Preventing COVID-19-Related Thromboembolic Events among Medicare Enrollees Aged ≥65 Years and Those with End Stage Renal Disease―Unites States, September 2022–March 2023 on January 11 in MMWR. A portion of the summary appears below. 

Thromboembolic complications of COVID-19 include ischemic stroke, venous thromboembolism, and myocardial infarction. COVID-19 vaccines are effective in preventing severe outcomes, including hospitalization and death. . . .

During September 2022–March 2023, receipt of bivalent mRNA COVID-19 vaccine was 47% effective in preventing thromboembolic events among immunocompetent persons aged ≥65 years and 51% effective among adults aged ≥18 years with end stage renal disease (ESRD) receiving dialysis, compared with receipt of the original monovalent vaccines alone. . . .

COVID-19 vaccines helped provide protection against COVID-19–related thromboembolic events. Persons aged ≥65 years and adults with ESRD should receive all recommended COVID-19 vaccine doses to prevent COVID-19–associated complications, including thromboembolic events.
