Fifteen years ago, Every Child by Two (now Vaccinate Your Family [VYF]) and the Autism Science Foundation first collaborated on a monograph sharing the science that shows there is no link between vaccination and autism spectrum disorders (ASD). They recently released an updated version of The Truth About Autism and Vaccines, which now includes discussion of current vaccine safety research and our current understanding of autism causes, signs, early diagnosis, and evidence-based treatments.
Use this guide to educate your communities and policymakers about the importance of ensuring that valuable research time and funding are dedicated to the most promising lines of inquiry related to the causes of and treatments for ASD.

It was corrected to display the correct range of 12–15 months.
Immunize.org has now corrected this error on all 17 translations of this patient handout. Updated translations include:

For week 11, ending March 15, CDC’s Weekly Influenza Surveillance Report, FluView, showed influenza-like illness activity at high to very high levels in 20 of 33 reporting jurisdictions. CDC classified this season as a high-severity season for people of all ages. During week 11, 3.9% of outpatient visits were for influenza-like illness, above the epidemic threshold of 3.0% for the sixteenth consecutive week. Seventeen pediatric deaths associated with seasonal influenza virus infection were reported during week 11, bringing the 2024–25 season total to 151 childhood deaths.
RESP-NET
Visit the CDC Respiratory Virus Hospitalization Surveillance Network (RESP-NET) for weekly reports of hospitalizations due to three vaccine-preventable seasonal respiratory viruses: COVID-19, influenza, and RSV. COVID-19 vaccination is recommended for everyone ages 6 months and older; RSV vaccination at this point in the season is recommended for certain high-risk adults ages 60 through 74 and all adults age 75 years and older. RSV immunization of infants and certain high-risk toddlers with nirsevimab (Beyfortus, Sanofi) is recommended until the end of March.
Influenza Vaccination Dashboard
CDC's Weekly Flu Vaccination Dashboard shows that as of February 22, an estimated 37.2 million doses of flu vaccine were given in community pharmacies (~317,000 fewer than this same time point last flu season) and 21.1 million doses were given in physicians’ medical offices (~4.2 million fewer doses than this same time point last flu season).
CDC recommends everyone age 6 months and older get annual influenza vaccination. Given the high levels of circulating influenza across the country, vaccination remains important for all eligible, unvaccinated people.
Identify pharmacies in your area that may offer influenza and COVID-19 vaccines by entering a zip code in the VaccineFinder on Vaccines.gov or Vacunas.gov.

"Reasons for 2024 ACIP Changes to Adult RSV Vaccine Recommendations": Watch the 2-minute answer, part of the Ask the Experts Video Series on YouTube.
Have you wondered why the ACIP recommendations for adult RSV vaccination were changed after just one season? This week, our featured episode from the Ask the Experts Video Series is titled Reasons for 2024 ACIP Changes to Adult RSV Vaccine Recommendations. The video explains how updated evidence on the balance of RSV vaccination benefits and risks led ACIP in June 2024 to make a definitive routine age-based recommendation for adults age 75 years and older, accompanied by a risk-based recommendation for those age 60 through 74 years with specific high-risk conditions.
The 2-minute video is available on our YouTube channel, along with our full collection of quick video answers to popular Ask the Experts questions.

Voices for Vaccines posted a new entry in its Vax Talk podcast series: Measles and Bird Flu and RSV–Oh My! featuring Joe Bresee, MD, on measles outbreak, influenza season, and H5N1 bird flu. A description from the VFV web page appears below.
In this episode, we break down the biggest vaccine headlines, from the alarming measles outbreak in Texas to the severity of this year’s flu season and the emerging threat of H5N1 bird flu. Special guest Dr. Joe Bresee from the Task Force for Global Health shares expert insights on pandemic preparedness, vaccine innovation, and global immunization efforts. He explains why bird flu is spreading among mammals, the risks of human-to-human transmission, and how surveillance is critical to preventing a future pandemic.
The episode also unpacks how avian flu could impact flu vaccine production, given that most vaccines still rely on chicken eggs, and why mRNA technology may be the future of flu prevention. Finally, the hosts dive into the fight against vaccine misinformation and hesitancy, exploring how behavioral science plays a key role in boosting vaccine confidence.

Confident healthcare provider recommendations for influenza vaccine are powerfully persuasive. This influenza season has been a tough one and it is not over yet. To help you maximize patient protection, Immunize.org, in collaboration with CSL Seqirus, updated the 65+ Flu Defense website.
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:
- Influenza in Adults 65+: The Facts
- Influenza Vaccination: Questions Patients Aged 65 and Older Frequently Ask Their HCP
- The Importance of Preventing Influenza and COVID-19
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 to assist your ongoing efforts in protecting this vulnerable population.
Immunize.org’s elegantly designed “Vaccines Save Lives” pins are meaningful gifts for people who care about vaccination.

Notable Publications
In the March 14 issue, Pediatrics published COVID-19 Vaccination During Pregnancy and Major Structural Birth Defects. Portions of the results and conclusions sections appear below.
Among 78,052 pregnancies, we identified 1248 major structural birth defects . . . 160.6 per 10,000 live births . . . among unvaccinated people and . . . 156.4 per 10 000 live births . . . among vaccinated people . . . No differences in the prevalence of major structural birth defects were observed given COVID-19 vaccination . . . Findings were unchanged by insurance provider, SARS-CoV-2 infection during pregnancy, and concomitant of other maternal vaccines. No differences in the prevalence of birth defects were observed among vaccinated people by brand . . .
COVID-19 vaccination during early pregnancy is not associated with an increased prevalence of major structural birth defects in infants. These results support the safety of COVID-19 vaccination in early pregnancy.
A video abstract is available.
On March 18, CDC issued a Health Alert Network (HAN) Health Update: Ongoing Risk of Dengue Virus Infections and Updated Testing Recommendations in the United States. CDC issued this HAN to provide additional information on dengue virus transmission in the United States, use of a specific assay when dengue is the most likely diagnosis, and new resources for investigating and responding to dengue cases in non-endemic areas of the United States.
