Happy holidays! IAC will begin 2022 with a new name and new logo. On January 12, IAC Express returns as IZ Express.

Clearly, 2021 has been the year of the vaccinator. The ACIP met 24 days of 2021 to establish, review, and revise vaccination recommendations. In the United States, 490 million doses of COVID-19 vaccines have been administered and 204 million people have been fully vaccinated against COVID-19. As detailed in the Commonwealth Fund report in Notable Publications below, COVID-19 vaccination efforts have already saved more than 1 million lives. It has been the privilege of our entire team to support you through it all.
IAC cherishes our 53,000 IAC Express subscribers and the 35,000+ people who visit our flagship website, every day. IAC began its mission to serve frontline vaccinators through advocacy and education 31 years ago. Many of you have relied on us for decades. However, there are newer frontline vaccinators, especially in the private sector, who are not aware of IAC and our mission to help all vaccinators deliver quality immunization services to people of all ages. In 2022, we are redoubling our efforts to increase our visibility and extend our reach.
In 2022, IAC will rebrand as By sharing our name with that of our flagship website, we hope to make it easier for more vaccinators to find us and our resources. In coming months, we will unveil a new website platform with a sleeker look and improved searchability and navigation. All of these changes are being designed with you and your needs in mind: thank you to those who have already completed our 3-minute user feedback survey to inform this important work. If you have not, you still have time to make your voice heard.
To align with our new name, IAC Express will return to your inbox after the holidays as IZ Express, subtitled Weekly News from It will come from the same email address; only the title will change.

Thank you for your loyal readership and for your tireless efforts to protect your communities from vaccine-preventable diseases. The whole IAC/ team wishes you and your loved ones a happy holiday season and a safe, healthy, fully vaccinated, and boosted 2022!

IAC summarizes December 16 ACIP meeting recommending preference for mRNA vaccines over Janssen vaccine to prevent COVID-19

The Advisory Committee on Immunization Practices (ACIP) met on December 16, 2021, to review the FDA’s December 14 revision of the Emergency Use Authorization (EUA) for Janssen (Johnson & Johnson) COVID-19 Vaccine. As outlined in the Janssen EUA Fact Sheets for Healthcare Providers Administering Vaccine and Recipients and Caregivers, FDA added a contraindication against administration of the Janssen vaccine to individuals with a history of thrombosis with thrombocytopenia syndrome (TTS) following receipt of Janssen or any adenovirus-vectored vaccine (e.g., AstraZeneca COVID-19 Vaccine, which is not authorized for use in the United States).
Fifteen cases of TTS following administration of the Janssen COVID-19 Vaccine were first reported in April 2021, largely in females younger than 50 years of age. Following a brief pause in vaccine use while additional data was gathered, ACIP at that time reaffirmed its recommendation for use of the Janssen vaccine with updated warnings about the potential for TTS, particularly in younger women.
Since April, CDC has continued to carefully monitor VAERS and other surveillance systems and has confirmed 54 cases of TTS reported following receipt of Janssen vaccine through August 2021. This larger number of cases includes both males and females in a wide range of ages, with the highest reported rate (~1/100,000 doses administered) in females 30–49 years of age. Approximately 15% of these TTS cases were fatal.
Updated risk-benefit calculations presented to ACIP demonstrated that the risk of the Janssen vaccine given to an authorized recipient remained much lower than the risk of going without vaccination against COVID-19. However, when compared to widely available mRNA vaccines, one dose of the Janssen vaccine prevented fewer hospitalizations, ICU admissions, and deaths and resulted in more severe health impacts from TTS and Guillain-Barré Syndrome (GBS). Therefore, ACIP unanimously voted to recommend a preference for using mRNA vaccines over the Janssen COVID-19 vaccine for the prevention of COVID-19 for all individuals 18 years of age or older. Janssen vaccine may continue to be used in certain situations, such as when an individual understands the risks and benefits and chooses the Janssen vaccine over mRNA vaccines, when the individual has a contraindication to an mRNA vaccine, or when access to mRNA vaccine is not possible. Considerations for Janssen COVID-19 Vaccine within CDC’s “Interim Clinical Considerations for Use of COVID-19 Vaccines Currently Approved or Authorized in the United States” contains detailed guidance on the new recommendation.
At the meeting, ACIP also heard an update on vaccine safety in children 5–11 years of age. As of December 9, more than 7 million doses of COVID-19 vaccine have been administered in this age group. Most reported adverse events occurred on the day of vaccination and were mild and transient in nature. There have been 14 reports of myocarditis to VAERS; of those, 8 reports (2 after dose 1, 6 after dose 2) have been confirmed to meet the case definition for mRNA vaccine-related myocarditis. CDC and FDA will continue to monitor for myocarditis and follow up on reports.
ACIP also reviewed the current status of the Omicron variant in the United States. CDC is closely monitoring transmission of this variant and its impact on the effectiveness of currently available COVID-19 vaccines. CDC will provide frequent updates to ACIP members as additional information becomes available.
The next scheduled ACIP meeting will be held February 23–24, 2022. Information about past and future ACIP meetings can be found on the ACIP website.

“Dengue Vaccine: Recommendations of the Advisory Committee on Immunization Practices, United States, 2021” published in MMWR

CDC published Dengue Vaccine: Recommendations of the Advisory Committee on Immunization Practices, United States, 2021 on December 17 in MMWR. A summary appears below.

In early 2022, the dengue vaccine Dengvaxia will be available for children 9–16 years old with laboratory-confirmed evidence of a previous dengue infection and living in areas where dengue is endemic in the United States. Dengvaxia is the first dengue vaccine approved by the U. S. Food and Drug Administration (FDA) and recommended by the Advisory Committee on Immunization Practices (ACIP) for use in areas where dengue transmission is frequent and continuous (endemic). Dengue-endemic areas include the U.S. territories of American Samoa, Puerto Rico, and the U.S. Virgin Islands (USVI), and freely associated states, including the Federated States of Micronesia, the Republic of Marshall Islands, and the Republic of Palau. … Dengvaxia, produced by Sanofi Pasteur, has an efficacy of about 80% in protecting children who have previously been infected with dengue against dengue illness, hospitalization, and severe disease.

The vaccine’s initial U.S. distribution will be in Puerto Rico, with expansion to other endemic areas later in 2022.

Flu activity in the United States continues to increase; get vaccinated as a safeguard this holiday season

Influenza Surveillance
For week 49, ending on December 11, CDC's Weekly U.S. Influenza Surveillance Report, FluView summary states that seasonal influenza activity in the United States continues to increase, including numbers of influenza-related hospitalizations.

Influenza Vaccination Dashboard
CDC's new Weekly Flu Vaccination Dashboard shares preliminary vaccination data. This week’s key fact: for children 6 months through 17 years, coverage among states and DC as of December 4, 2021, varies widely, ranging from 20.1% to 64.2%; overall national coverage is 43.4%.

CDC recommends everyone age 6 months and older get an annual flu vaccine. Influenza and 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. 

Vaccine Finder
If you don’t provide influenza vaccine at your site, please strongly recommend vaccination and refer people to sites that do vaccinate. Use VaccineFinder, a user-friendly website to help people of all ages find influenza, COVID-19, and other vaccines. Participating providers can update their vaccine inventory estimates on VaccineFinder. For questions or more information, contact

Becker's Hospital Review publishes "Protect against the Omicron Variant of COVID-19 AND Influenza This Winter" by IAC authors

On December 17, Becker's Hospital Review published Protect against the Omicron Variant of COVID-19 AND Influenza This Winter, written in collaboration with IAC. An excerpt from the article is reprinted below.

Healthcare providers’ reminders and recommendations are key to improving uptake of vaccines, including influenza. Recent surveys from the National Foundation for Infectious Disease show that less than half of adults with a chronic condition report having received an influenza vaccine as of early November. Additionally, less than a third of healthcare providers say they recommend annual influenza vaccines to all of their patients with chronic health conditions. … 
Time is of the essence. Vaccinate now, before the wave of influenza season begins its seasonal surge.

“The U.S. COVID-19 Vaccination Program at One Year: How Many Deaths and Hospitalizations Were Averted?” published by the Commonwealth Fund

In the December 14 issue, the Commonwealth Fund published The U.S. COVID-19 Vaccination Program at One Year: How Many Deaths and Hospitalizations Were Averted? The authors calculate that, in the absence of a vaccination program, there would have been approximately 1.1 million additional COVID-19 deaths and more than 10.3 million additional COVID-19 hospitalizations in the United States by November 2021. A portion of the discussion section appears below.

Our findings highlight the ongoing tragedy of preventable death and hospitalization occurring among unvaccinated Americans. Daily vaccination rates have ticked up recently but only recently to 60 percent of the U.S. population—a lower rate than that achieved by dozens of other countries. As immunity wanes and breakthrough infections continue to emerge, it is clear we must vaccinate (and give booster shots) to many more people—building on the tremendous, though mostly invisible, successes the U.S. vaccination program has accomplished thus far.

“Report of Health Care Provider Recommendation for COVID-19 Vaccination among Adults, by Recipient COVID-19 Vaccination Status and Attitudes—United States, April–September 2021” published in MMWR

CDC published Report of Health Care Provider Recommendation for COVID-19 Vaccination among Adults, by Recipient COVID-19 Vaccination Status and Attitudes—United States, April–September 2021 on December 17 in MMWR. A summary appears below.

To examine the impact of a provider recommendation on COVID-19 vaccination, CDC analyzed data from a nationally representative household survey of COVID-19 vaccination status, attitudes, and behaviors among adults. Adults who reported a provider recommendation were more likely to have received at least one dose of a COVID-19 vaccine (78%) than those who did not receive a recommendation (62%). A healthcare provider’s recommendation was associated with higher vaccination coverage, including among younger adults (18–29 years), some racial and ethnic minorities, and people living in rural areas. Furthermore, a provider recommendation was associated with increased confidence that the vaccines are safe and important for protection against COVID-19. Healthcare providers … can serve as key influencers in decisions by patients to get vaccinated and can contribute to improving vaccine confidence.

“Association of Maternal Cervical Disease with Human Papillomavirus Vaccination among Offspring” published in JAMA

In the December 13 issue, JAMA published Association of Maternal Cervical Disease with Human Papillomavirus Vaccination among Offspring. The conclusions section appears below.  

The findings of this time-to-event cohort study suggest that children whose mothers had a history of cervical cancer or cervical abnormalities requiring biopsy were not more likely to vaccinate their children against HPV, despite their personal experience with vaccine-preventable adverse outcomes. These findings also suggest that mothers with a history of adverse cervical outcomes may be either unaware of the causal link between HPV and cervical disease or that from a behavioral perspective, increased salience of the risks of HPV does not outweigh other factors that contribute to vaccine hesitancy.
