We have vaccines, now comes the hard part
Recent good news on vaccines for COVID-19 brings us closer to ending the acute phase of this terrible pandemic. But the sense of collective relief must be accompanied by a healthy dose of reality.

This means that mitigation measures¾mask-wearing, social distancing, avoiding large crowds, and practicing good hygiene¾will likely be necessary for the foreseeable future.
