When you get COVID-19, the biggest fear is ending up in the hospital. A new look at patients in California who took the antiviral drug Paxlovid found that, after treatment, they had low rates of hospitalizations and emergency department visits. This is an encouraging sign that the treatment might be helping people stay out of the hospital.
However, it's important to understand what this study can and cannot tell us. This was an observational look back at patient records, not a controlled experiment. The researchers didn't compare these Paxlovid patients to similar people who didn't get the drug, so we can't say for sure that Paxlovid caused the low hospitalization rates. Other factors could have played a role.
We also don't know the exact numbers—how many people were in the study or precisely how low the rates were. The findings are specific to patients in California, and we don't have information on side effects from this report. While it's a positive signal that aligns with what we hope the drug does, this early data needs to be followed by more rigorous research to confirm the results and understand the true benefit.
