NASN and Sanofi Pasteur have joined forces to launch Stats4Vax: Improving teen vaccination rates one school nurse at a time (Stats4Vax). This new program provides resources to guide conversations with parents/guardians to see that teens are up-to-date on their immunizations. Nurses in all states can access the resources, and this school year, those in NC, CA, and FL are invited to pilot the Challenge encouraging high school nurses to track and improve teen vaccine rates (which are dismally low for some vaccines!).
