US President Joe Biden is trying to beef up access to home COVID-19 tests. In his remarks on Thursday, he’s expected to announce that more than 150 million Americans with private health insurance will be able to get the tests reimbursed by their insurers. In Britain and other parts of Europe, at-home COVID-19 tests have long been available for free and have become a part of everyday life. Marco Werman speaks about the different approaches that many other countries have taken with home tests with Oksana Pyzik, a global health adviser and lecturer at University College London.
