This is the most common issue. Make sure your computer is set up with:

    The Preparing Vaccines lesson does not work with Firefox or Safari.

  3. JavaScript and pop-ups enabled


Problem advancing to the next page:

  • If you can’t advance to the pre- or post-lesson checks, please try updating your computer with system requirements above. 
  • EZIZ lessons require all buttons clicked, questions answered, or audio to finish before proceeding to the next page. Be sure to click on any buttons or photos according to instructions.
  • If you have already clicked on everything and the Next button still does not work, the two most common problems are:
  1. A glitch occurred during page loading.
    Delete your browser history (temporary internet files/cache/history, exit all web browser windows, and re-access the lesson.
    Follow these instructions for deleting the temporary internet files:
    Internet Explorer
  2. The computer you are working on is behind a content filtering system (ie. it blocks you from accessing certain websites like entertainment or game websites).
    Please request your IT department whitelist “” and “”. This will ensure that no files are being restricted from loading.
