You would want to use register() or preRegister() to register the variables to the template. The difference is that register() needs to be called when the template is being rendered, where preRegister() can be called any time before. So it depends on how your code is set up. Assuming you're rendering your own template, you probably have something like:

$template = vB_Template::create('mytemplate');
// register variables here
$template->register('mycarekeywords', $mycarewords);
$template->register('mycaredescription', $mycaredescription);
print_output($template->render());

so you'd want to add those two middle lines.
