During a briefing, the epidemiologist Maria van Kerkhove warned that COVID-19 vaccines, shortly, might be "ineffective" against a "constellation of mutations." However, there is a "next generation of vaccines" that could fight the pandemic.
On Monday, the WHO reported that globally new cases have declined for eight weeks in a row, and deaths have decreased for seven consecutive weeks. "This is good news, but new infections and deaths remain high globally," the WHO Director-General Tedros Adhanom said.
Moreover, "while a handful of countries have high vaccination rates & are now seeing lower numbers of hospitalizations and deaths, other countries in Africa, the Americas and Asia are now facing steep COVID-19 epidemics. These cases and deaths are largely avoidable," the official added.
