As COVID-19 vaccines are rolled out around the world, a top doctor is warning of a new virus strain that is killing the young in their thousands.
Brazil is swamped by new virus cases, with a warning to Australia that this variant is far more dangerous than anything seen before.

The Brazilian variant, known as P1, has been described as like a viral match to kerosene. It's up to 150 per cent more infectious than regular COVID-19 and attacks people in their 30s, 40s and 50s.
"P1 could be the variant that is the big troublemaker for the next surge," he said.

In just one month, Brazil's daily deaths have surged well past 3000 a day.
The variant has already made its way to Canada, to a Whistler ski resort that's popular with Australians, while 16 players in the professional ice hockey team the Vancouver Canucks have caught it too.
"There are cases here with the Canucks where the individuals here are very ill," Canadian sportscaster Darren Dreger said.
Dr Feigl-Ding, who is a Senior Fellow at the Federation of American Scientists, said it should serve as a warning to many, particularly Australians.
