Biden's Covid-19 Promises Aren't All Scientifically Possible Yet

Biden’s most notable comment on the virus was the promise to make testing widely available at pharmacies and allow those who test positive to get free access to antiviral pills. That makes sense because in clinical trials, Pfizer’s drug Paxlovid showed close to 90% efficacy at reducing hospitalizations when given to people who test positive for Covid-19 within five days of reporting symptoms. But giving away Paxlovid isn’t quite that simple, because the drug interferes with the absorption of other drugs. Many people who are vulnerable enough to be good candidates for Paxlovid are going to be on multiple other drugs and would need a doctor’s supervision to take the five-day course of pills safely.
