Informed consent is a principle in medical ethics, medical law and media studies, that a patient must have sufficient information and understanding before making decisions about their medical care. Pertinent information may include risks and benefits of treatments, alternative treatments, the patient's role in treatment, and their right to refuse treatment. In most systems, healthcare providers have a legal and ethical responsibility to ensure that a patient's consent is informed. This principle applies more broadly than healthcare intervention, for example to conduct research and to disclose a person's medical information.
The booster shots are not mandatory in most countries. Your doctor should have informed you of the benefits and side effects of the booster shots, so there's no point in commenting on it here.
