Usage edit
This is a simple navigation template based on {{navbox}}.
To use, copy and paste {{Vaccine safety}} at the bottom of an article.
The template is suitable for transcluding at the bottom of articles related to Vaccine safety.
This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.
To change this template's initial visibility, the |state= parameter may be used:
{{Vaccine safety|state=collapsed}}will show the template collapsed, i.e. hidden apart from its title bar.{{Vaccine safety|state=expanded}}will show the template expanded, i.e. fully visible.
