Where things stand This is the final edition of our Solving COVID newsletter. The pandemic is by no means over, but in a sense, COVID has indeed been "solved." We now know that vaccines are the way out of this crisis. A number of them have proven remarkably effective at preventing severe illness and death, and at reducing spread of the virus. Over time we will fine-tune vaccination programs as we learn more about dosage, boosters, and long-term immunity. COVID-19 may never disappear completely, but with these potent tools in-hand, we are well equipped to bring it to heel. The international challenge we face is getting these shots into as many arms as possible, especially in areas with high-risk populations. If we fail, we risk prolonging the pandemic and endangering the progress we've made should a new vaccine-resistant variant emerge and sweep across the globe in yet another devastating wave. Let us hope we win this race against time.
