Coronavirus: vaccines ‘surest way to prevent more deaths’ as global toll hits 4 million

The pandemic has cost Nairobi health care worker Mary Nanjala dearly. Her two sisters, brother and mother were all infected with Covid-19, and two close friends have died of complications from the disease.

“One friend was buried last Friday. This has left me very scared as the deaths came too near. We were very close friends,” Nanjala said. “I feel very sad as my friends were young and left behind children.”
