Face masks are still an effective way to help stop the spread of the BA.5 subvariant.
The last Omicron wave affected younger people. But the new BA.5 variant is seeing case numbers in older age groups higher than ever before – just as hospitals are under the most pressure.
Is it time for a new generation of COVID vaccines? Here’s where the research is at.
Achieving herd immunity via vaccination was always going to be a hard ask. Now it’s mathematically impossible.

With the relaxation of mask-wearing mandates, there’s even more need to know how much over-the-counter tests help.
It’s hard to keep up. But new Omicron sub-variants are emerging that may lead to reinfections and another spike in cases.
Final approach on the air charter into the Voisey’s Bay mine, a fly-in/fly-out nickel, copper and cobalt mine located near Nain, Nunatsiavut, in northern Labrador.
