Fully vaccinated people asymptomatic if infected with Covid delta variant, says WHO
The variant is spreading quickly and infecting unprotected and vulnerable people
Though many people who are fully vaccinated still getting infected with Covid-19 delta variant, the shots are protecting them from being severely sick or dying according to The World Health Organization.
"There are reports coming in that vaccinated populations have cases of infection, particularly with the delta variant," Dr. Soumya Swaminathan, the World Health Organization's chief scientist, said at a press briefing Monday. "The majority of these are mild or asymptomatic infections," reports CNBC.
However, hospitalizations are rising in some parts of the world, mostly where vaccination rates are low and the highly contagious delta variant is spreading, she said.

In the US, officials have said virtually all recent Covid hospitalizations and deaths were occurring among unvaccinated people. Breakthrough infections are rare, and about 75% of the people who die or are hospitalized with Covid after vaccination are over the age of 65, according to data from the Centers for Disease Control and Prevention.
"The delta variant is ripping around the world at a scorching pace, driving a new spike in cases and death. Not everywhere is taking the same hit, though," WHO Director-General Tedros Adhanom Ghebreyesus said. "We are in the midst of a growing two-track pandemic where the haves and have-nots within and between countries are increasingly divergent in places with high vaccination coverage."
The variant is spreading quickly and infecting unprotected and vulnerable people, he said.
Swaminathan warned that vaccinated people can still get Covid and pass it on to others, which is why WHO officials have been urging people to continue wearing masks and practice social distancing. "But certainly it reduces your chances of severe hospitalization and death significantly," she added.
Some studies have shown that those infected with Covid after vaccination produce much less virus than those who are unvaccinated, reducing the risk of passing the virus to others. WHO officials said that more studies are needed to understand the vaccines' impact on transmissibility.
