Nirmatrelvir is an oral protease inhibitor that is active against MPRO, a viral protease that plays an essential role in viral replication by cleaving the 2 viral polyproteins.1 It has demonstrated antiviral activity against all coronaviruses that are known to infect humans.2 Nirmatrelvir is packaged with ritonavir (as Paxlovid), a strong cytochrome P450 (CYP) 3A4 inhibitor and pharmacokinetic boosting agent that has been used to boost HIV protease inhibitors. Not only will this help to produce a more robust antibody response, but by the time youre ready to be boosted, there might be a newer version of the vaccine available that will specifically work against Omicron.
