Canadian Prime Minister Justin Trudeau said Friday that his country is doing its part to help poorer nations gain access to COVID-19 vaccines. Trudeau was responding to a question whether a country like Canada should forego booster shots to allow poorer nations better access to vaccines. "It's not always enough to re-direct vaccines that we've purchased or paid for to go to countries around the world, we need to be sending money as well to invest in the logistical chains or hubs," Trudeau said.
