Dr. Laura Ward says there is already evidence that breast milk contains antibodies which help protect against lower-respiratory issues.

Israel targets flights, religious scofflaws, as virus rages
Prime Minister Benjamin Netanyahu on Sunday said Israel will be closing its international airport to nearly all flights, while Israeli police clashed with ultra-Orthodox protesters in several major cities and the government raced to bring a raging coronavirus outbreak under control.
The entry of highly contagious variants of the virus, coupled with poor enforcement of safety rules in ultra-Orthodox communities, has contributed to one of the world's highest rates of infections. It also has threatened to undercut Israel's highly successful campaign to vaccinate its population against the virus.
In just a month, Israel has vaccinated over a quarter of its 9.2 million people. At the same time, the virus continues to race through the country, with authorities confirming an average of over 8,000 new cases a day.

France faces 3rd lockdown if curfew not enough
France's government may impose a third lockdown in the coming days if an existing 12-hour-a-day curfew doesn't significantly slow virus infections.
Exactly a year after France announced Europe's first confirmed case of the coronavirus, Health Minister Olivier Veran said in an interview published Sunday in the Le Parisien newspaper that if infections don't drop, and "if the variants start to spread everywhere, we will take extra measures. And that's called confinement. ... We will close down."
An official in French President Emmanuel Macron's office said Sunday that "everything is on the table" but no firm decisions will be made until the effect of the nationwide 6 p.m.-6 a.m. curfew is clear in the coming week.
