CDC published Cholera Vaccine: Recommendations of the Advisory Committee on Immunization Practices, 2022 in the September 30 issue of MMWR Recommendations and Reports. A portion of the summary appears below.

Cholera is rare in the United States, but cases occur among travelers to countries where cholera is endemic or epidemic and associated with unsafe water and inadequate sanitation. Travelers might be at increased risk for poor outcomes from cholera if they cannot readily access medical services or if they have a medical condition that would be worsened by dehydration, such as cardiovascular or kidney disease. This report describes previously published ACIP recommendations about use of CVD 103-HgR for adults aged 18–64 years and introduces a new recommendation for use in children and adolescents aged 2–17 years. ACIP recommends CVD 103-HgR, the only cholera vaccine licensed for use in the United States, for prevention of cholera among travelers aged 2–64 years to an area with active cholera transmission. Health care providers can use these guidelines to develop the pretravel consultation for persons traveling to areas with active cholera transmission.

Influenza season has begun. CDC expects influenza activity, which is currently low, to increase in the coming weeks or months. CDC’s Weekly U.S. Influenza Surveillance Report, FluView, provides a valuable snapshot of influenza activity state-by-state.

Influenza Surveillance
For week 38, ending September 24, CDC's Weekly U.S. Influenza Surveillance Report, FluView summary reports that, nationwide, 2.2% of patient visits reported through the Outpatient Influenza-Like Surveillance Network (ILINet) were due to respiratory illness that included fever plus a cough or sore throat (i.e., influenza-like illness [ILI]). Multiple respiratory viruses are co-circulating, and the relative contribution of influenza virus infection to ILI varies by location.



Influenza Vaccination Dashboard
CDC's Weekly Flu Vaccination Dashboard data show that 71.4 million doses of influenza vaccine have been distributed in the United States through September 17, 2022. Vaccine manufacturers project that they will supply the United States with 173.5 million to 183.5 million doses for the 2022–23 season.

CDC recommends everyone age 6 months and older get annual influenza vaccination. Influenza and other vaccines (e.g., COVID-19 vaccines) may be given at the same visit, if needed. COVID-19 vaccination alone provides no protection from influenza or any other respiratory virus. To be listed as a provider by VaccineFinder, see the information at this website.

If you don’t provide influenza vaccine at your site, please strongly recommend vaccination and refer people to sites that do vaccinate. The American College of Physicians offers free Adult Vaccination Prescription Pads listing ACIP-recommended vaccines for adults to enable easy referral to vaccinating sites.



“Vaccines.gov” offers VaccineFinder, a service of Boston Children’s Hospital, to help people find influenza, COVID-19, and other vaccines for any age group.

Immunize​.org's www.Give2MenACWY.org website promotes the importance of adolescent vaccination, including the recommended MenACWY vaccine booster dose at age 16. Many teens are behind on vaccines because of the pandemic, so vaccination is more important than ever.

Materials on this colorful website for healthcare professionals incorporate the 2020 ACIP meningococcal vaccine recommendations and coverage statistics from CDC’s National Immunization Survey–Teen (NIS–Teen). One particularly popular resource on the site is the updated Algorithm for MenACWY Immunization in Adolescents 11 through 18 Years of Age.

The website is divided into five easy-to-access sections:

• Vaccinate Teens – Teen vaccination schedules and tips for improving vaccination rates
• Give 2 Doses – Tools to help improve second dose coverage of MenACWY vaccine
• 16-Year-Old Visit – Resources to help providers and patients remember the important vaccines recommended for 16-year-olds
• Tools for Providers – Tools to explain meningococcal ACWY vaccine recommendations and improve coverage for all adolescent vaccines
• Resources – Links to print materials, organizations involved in adolescent vaccination, personal stories about the importance of vaccination, and other resources of interest

The site also categorizes materials according to whether they are primarily of interest to providers, to adolescents, or to parents.

In its article-in-press version, Academic Pediatrics released Association between Aluminum Exposure from Vaccines before Age 24 Months and Persistent Asthma at Age 24 to 59 Months. A portion of the article, written by Vaccine Safety Datalink (VSD) investigators (including CDC), appears below.

In a large observational study, a positive association was found between vaccine-related aluminum exposure and persistent asthma. While recognizing the small effect sizes identified and the potential for unmeasured confounding, additional investigation of this hypothesis appears warranted.

On September 27, NIH announced results of an international study, linking a temporary increase of less than 1 day in menstrual cycle length with COVID-19 vaccination. The study was published in BMJ Medicine, and titled Association between Menstrual Cycle Length and COVID-19 Vaccination: Global, Retrospective Cohort Study of Prospectively Collected Data. The first paragraph of the press release appears below.

A large international study has confirmed the findings of a previous U.S. study that linked COVID-19 vaccination with an average increase in menstrual cycle length of less than one day. The increase was not associated with any change in the number of days of menses (days of bleeding). Funded by the National Institutes of Health, the new study included data from nearly 20,000 people from Canada, the United Kingdom, the United States, Europe and other parts of the world who received any of nine different vaccines. For most study participants, the increase resolved in the cycle following vaccination.

JAMA Network published Estimation of COVID-19 mRNA Vaccine Effectiveness against Medically Attended COVID-19 in Pregnancy during Periods of Delta and Omicron Variant Predominance in the United States on September 26. The conclusions and relevance section appears below.

In this study, maternal mRNA COVID-19 vaccination, including booster dose, was associated with protection against medically attended COVID-19. VE [vaccine effectiveness] estimates were higher against COVID-19–associated hospitalization than ED/UC [emergency department or urgent care] visits and lower against the Omicron variant than the Delta variant. Protection waned over time, particularly during Omicron predominance.

CDC published Widespread Hepatitis A Outbreaks Associated with Person-to-Person Transmission—United States, 2016–2020 in the September 30 issue of MMWR. A portion of the summary appears below.

Hepatitis A epidemiology in the United States has shifted as a result of recent and ongoing outbreaks associated with person-to-person transmission. During August 1, 2016–December 31, 2020, 33 states reported hepatitis A outbreaks involving approximately 37,500 cases. Among cases with available information, 56% of persons reported drug use, 14% reported homelessness, and 61% were hospitalized; 380 outbreak-associated deaths were reported. . . .

Increased hepatitis A vaccination coverage, through implementation of nontraditional vaccination strategies to reach disproportionately affected populations, along with improved universal and catch-up childhood vaccination, will be necessary to respond to the current hepatitis A outbreaks and prevent similar outbreaks in the future.

CDC published Effectiveness of a Second COVID-19 Vaccine Booster Dose against Infection, Hospitalization, or Death among Nursing Home Residents—19 States, March 29–July 25, 2022 in the September 30 issue of MMWR. A portion of the summary appears below.

In a large cohort of nursing home residents, receipt of a second mRNA COVID-19 booster dose during circulation of SARS-CoV-2 Omicron subvariants was 74% effective at 60 days against severe COVID-19–related outcomes (including hospitalization or death) and 90% against death alone compared with receipt of a single booster dose. . . .

Efforts should be made to ensure that nursing home residents remain up to date with recommended booster doses of COVID-19 vaccines.
