One of the reasons for this difference is that infections trigger many different parts of the immune system, and the size of the antibody response will depend on factors like how much virus you inhaled, whether you have underlying medical conditions and the severity of your symptoms. Ritonavir-boosted nirmatrelvir is not recommended for patients with known or suspected severe hepatic impairment (i.e., Child-Pugh Class C), and it should be used with caution in patients with pre-existing liver diseases, liver enzyme abnormalities, or hepatitis.
