President Biden plans to welcome Prime Minister Justin Trudeau and a delegation of Canadian officials to the White House on Tuesday – a virtual session due to COVID-19 constraints that will try to recreate some of the ceremonial flourishes of an in-person visit to Washington.

Biden and Trudeau plan to discuss the public health and economic crises caused by the pandemic, as well as shared goals on addressing climate change, addressing racism and discrimination, and other issues, a senior U.S. administration official told reporters ahead of the meeting.

Japan may have several million fewer coronavirus vaccine doses than originally planned because the country does not have the appropriate syringes. It's another setback to one of the slower vaccination rollouts among developed economies.

The Pfizer vaccine normally contains five doses per vial. But a special syringe known as a low dead space syringe, which expels more medicine from the space between a syringe's needle and plunger, can eke out six doses per vial.

China has approved one domestic coronavirus vaccine for commercial use. Four more are in late stage human trials, and a nationwide vaccination campaign is already underway.

Dr. Anthony Fauci said Friday he welcomes the positive news about an additional COVID-19 vaccine announced in the past 24 hours, calling the results "really encouraging." And he added that the Biden administration hoped to be able to start vaccinating children by late spring or summer.

It may seem counterintuitive, but health officials say that even after you get vaccinated against COVID-19, you still need to practice the usual pandemic precautions, at least for a while. That means steering clear of crowds, continuing to wear a good mask in public, maintaining 6 feet or more of distance from people outside your household and frequently washing your hands. We talked to infectious disease specialists to get a better understanding of why.

Why do I have to continue with precautions after I've been vaccinated?

India's drug regulators gave the country a gift on New Year's Day: a vaccine against the coronavirus.
