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 Texas, the Family Code outlines who has the authority to consent to medical, dental, psychological, and surgical treatment for a minor child. Generally, a parent or legal guardian has the right to consent to the child's treatment. However, there are exceptions where others may consent, such as when a court has granted managing conservatorship to an individual, or when a minor is authorized by law to consent to their own treatment in certain circumstances, such as when they are on active duty with the armed forces, are 16 years or older and live separately from their parents, or have a child or are pregnant, among other situations. Additionally, Texas law allows minors to consent to vaccinations in specific instances, such as when it is recommended by a health care practitioner for a minor's known medical condition. It's important to note that Texas may have specific statutes regarding the consent for vaccinations, especially in light of public health concerns, and these can be subject to change. An attorney can provide the most current legal advice regarding these matters.
