Laws vary from state to state, but many states have laws (statutes) enacted by their state legislatures that determine which persons have the legal authority to consent to medical treatments, medical procedures, and vaccinations (also known as immunizations or inoculations) of minor children (generally under the age of 18).
In Washington State, the authority to consent to medical treatments, procedures, and vaccinations for minor children is generally vested in their parents or legal guardians. However, Washington law also allows for certain exceptions where minors can consent to their own medical care. For example, minors who are 13 years of age or older can consent to outpatient mental health treatment without parental consent under certain conditions. Additionally, minors may consent to reproductive health services at any age. Washington State also has specific laws regarding vaccinations, such as the Mature Minor Doctrine, which may allow a minor deemed sufficiently mature by a healthcare provider to consent to vaccinations. It is important to note that these laws are subject to change and can be complex, so consulting with an attorney for current and personalized legal advice is recommended.
