Swedish climate campaigner Greta Thunberg has donated 100,000 euros ($120,000) from her foundation to the Covax scheme for equitable access to Covid-19 vaccines, the World Health Organization announced Monday. "The international community must do more to address the tragedy that is vaccine inequity," 18-year-old activist Thunberg said. "Just as with the climate crisis, we must help those who are the most vulnerable first." rjm/vog/kjl
