Hyderabad:The coronavirus pandemic has infected more than 6,62,46,564 and killed over 15,24,731 people across the world. More than 4,58,28,772 people have recovered so far.
The US is the worst-hit nation with cases more than 1,47,72,535 and fatalities over 2,85,550.
The Covid-19 pandemic has not settled down into a predictable pattern, as the situation of transmission and cases in different countries varies a lot, said an expert from World Health Organization (WHO), noting there's no one-size-fits-all solution globally.
Speaking at a virtual press conference on Friday, Mike Ryan, Executive Director of the WHO's Health Emergencies Program, cautioned that "vaccines do not equal zero Covid" and that vaccines and vaccination "will only add a major powerful tool to the toolkit we have now."
