How do you figure out how effective a vaccine needs to be if you can’t test it widely on humans? A team of health and computer scholars took up that challenge, and they have a warning for anyone counting on a vaccine to mean the end of social distancing. They created a computer simulation of every person in the United States to test how effective a vaccine would have to be for America to confidently stop social distancing. It turns out it isn’t just about the vaccine – human behavior also plays a crucial role.
The East African Community has been in place for two decades. In that time membership has increased and the bloc has launched a number of successful initiatives. But there are enduring tensions which the COVID-19 pandemic has brought into sharp relief. Peter O'Reilly and Chris Vaughan explain how member states have failed to co-ordinate their activities in responding to the pandemic. They also point out how the enduring appeal of the EAC’s ideals has been kept alive by civil society and the business community.
