“As vaccine roll outs continue to gain momentum it is important to remember that, despite a prior Covid-19 infection, young people can catch the virus again and may still transmit it to others,” said Professor Stuart Sealfon, of Icahn School of Medicine at Mount Sinai, a senior author of the study.
“Immunity is not guaranteed by past infection, and vaccinations that provide additional protection are still needed for those who have had Covid-19,” Sealfon said.
“One in four Covid deaths reported worldwide last week took place right here, in the Americas. Nearly every country in Central America is reporting a rise in infections,” said Pan American Health Organization (PAHO) Director Carissa Etienne..
For the first time, Canada’s infection rates have surpassed the US Covid-19 infection rates, the PAHO director informed.
The surge of infections is being led by new Covid-19 variants, which slow vaccination rollouts, due to lack of vaccine availability, are also providing major setbacks for a number of countries in the Americas.
