Parathyroid is one of the biggest health threats facing the world, with around one in four people over 65 having it, according to the World Health Organization.

A vaccine for it has been in the works for decades, but only recently have we seen it get a significant boost in popularity.

Here are three tips to help you get the best benefit from a vaccine.

1.

Don’t be afraid to test Your doctor will know your symptoms and take a test if he or she feels there’s something you need help with.

But testing can also be a great way to find out how well you’re immune to the disease.

2.

Don’T be afraid of testing again, or even after you get a vaccine If you’re not feeling well and want to test, it can be hard to keep it a secret.

If you can’t be completely comfortable with the idea, testing might be a good way to help with that.

3.

Be ready for the inevitable It’s easy to get too wrapped up in the results.

But if you’re a bit nervous about testing, make sure you test every three months or so, and try not to rush.

If anything else happens, like you experience side effects, you can always go back to your previous tests.
