Johannesburg, South Africa CNN  — 

The funeral pyres in New Delhi tell the tragic story of an uncontrolled Covid-19 wave.

For a world that’s grown numb to wave after wave of infection, the images of patients dying due to a lack of oxygen while others lie untended on the floor are a brutal reminder that this pandemic is far from over.

In late March, in a desperate attempt to curb infection, the Indian government restricted the export of Covid-19 vaccines from its giant manufacturing hubs, to meet some of the country’s more urgent needs. Now, the consequences of that move are playing out across the world.

Kenya’s President Uhuru Kenyatta personally assured Kenyans they would be able to get their second dose if they’d received a first one.

But Martin Mutisya, a 53-year-old tour guide, has been keeping up with news – he knew he had to hurry just to get his first shot.

“I am concerned, because there are supposed to be two shots, but if that doesn’t happen, what is the worst-case scenario?” he asked.

The worst-case scenario is now happening, said World Health Organization (WHO) and Kenyan public health officials. The East African nation will run out o
