Is it malpractice for a doctor not to take a patient's vital signs?

Let's assume it was malpractice. What are your damages? Medical malpractice cases are very expensive to pursue because you need an expert witness to establish the negligence and that costs thousands of dollars.

It is a departure from accepted standards of practice but unless that caused significant injury there is no legal action to take in response to it.

Every little misstep is not malpractice in a legal sense. To be legally malpractice, the negligence must be causally related to damages caused. In your case it seems none really happened. BUT you should mention this to your doctor.

Malpractice has a couple of parts in order to be actionable. The two main parts include violation of the standard of care and actual damage. It is unusual for a PCP to fail to take vital signs and that might well be a violation of the standard of care, but it doesn't sound as if you experience any damage as a direct result of that violation. Given that, you wouldn't have a malpractice claim. You might want to talk to your doctor about this issue and/or consider finding a new doctor.

Did you suffer any injury or damages as a result of the doctor failing to take your vital signs. Without a provable injury you will not be able to move forward with any legal claim. Good luck,
