Covid: Five things we still need to keep an eye on

Why is it important? Some scientists think this is the single most important issue in the months ahead. We are familiar with hard-to-treat superbugs, from MRSA to super-gonorrhea, which were created by misusing antibiotics. The same process can happen with antivirals. These drugs, such as Paxlovid and molnupiravir, are currently playing a vital role in saving lives and are one reason restrictions are being eased. Even more importantly, they are the safety net in the future. If a new variant emerges that significantly bypasses our immunity, we will be dependent on antivirals to buy us time until an updated vaccine can be developed and rolled out.
