Maryland-based Novavax has sent millions of COVID vaccine doses to wealthy nations and none to the initiative that supplies poorer countries

The company behind a COVID-19 vaccine touted as a key tool for the developing world has sent tens of millions of doses to wealthy nations but provided none yet to the U.N.-backed effort to supply poorer countries, a sign that inequity persists in the global response to the pandemic. A quarter-million doses from the company were supposed to be available to the vaccine-sharing initiative, called COVAX, by March. But the U.N. agency in charge of deliveries says the first shipments now likely won’t be made until April or May.
