About Vaxnext
Last updated: September 18, 2026
Vaxnext is a family vaccine tracker app for iPhone and Android, and this website is where its guides live. This page says who publishes them, how they are written, what they are not, and how to tell us when something is wrong.
1. Who publishes Vaxnext
Vaxnext, the app and the website, is published by SMARTNESS HOME, a company whose registration details, postal address and contact e-mail are on the Legal Notice.
Articles are signed "Vaxnext". They are written and maintained by the small team that builds the app — not by a guest author, a content agency or an automated writer. Nobody on that team holds a medical license, and no article claims otherwise.
2. How the guides are written
Every guide starts from an official source: a CDC page (the child and adolescent immunization schedule, Travelers’ Health, the Yellow Book), an American Academy of Pediatrics or HealthyChildren.org page, a WHO or NIH page, or a state health department. The source is linked in the body of the article where the fact appears; some guides also say on which day that page was checked.
Doses, ages and intervals are copied from those pages, not summarized from memory. Before it is published, each article passes an automated check that requires at least one official source, a medical disclaimer, and no claim about the app that the app does not deliver.
3. How often the guides are reviewed
Each article shows a Published date and, once it has been revised, an Updated date. The same dates feed the page’s structured data and the sitemap, so what you see is what search engines see.
Every article is re-checked against its sources at least once a year, and earlier when the CDC or the AAP changes a page it cites or when a federal recommendation is announced. The most recent site-wide review was completed on September 3, 2026.
4. Not reviewed by a clinician
Vaxnext articles are not reviewed by a physician, a nurse or a pharmacist before publication. They are general information based on public schedules, and they do not replace medical advice. A decision about a vaccine, for you or for your child, belongs with a doctor, a pharmacist or a public health authority who knows the person in front of them.
The same applies to the app: it compares the doses you enter against the published schedule. It is not a medical device.
5. Reporting an error
If you find a mistake, a broken link or an outdated figure, write to the contact e-mail listed on the Legal Notice. Say which article and which sentence. A confirmed error is corrected and the article’s Updated date moves.
General information — not medical advice.
