A new meta-analysis of studies involving more than 14 million people published in the Journal of Infection shows that COVID-19 vaccination is associated with a lower risk of developing long COVID, with two doses reducing the odds by 24% and one dose reducing the odds by 15%.
Reduced gas exchange in the lungs -- oxygen coming in, carbon dioxide going out -- appears to be associated with brain fog in long COVID, researchers will report in Chicago at next week's annual meeting of the Radiological Society of North America.
A new research letter published yesterday in JAMA Network Open shows no new safety concerns or reactogenicity signals among babies and toddlers who received their first COVID-19 vaccines by the age of 2.
California's health department confirmed the case through lab testing. The patient contracted it after traveling from East Africa, where there has been an outbreak of the clade I strain. The person was treated in San Mateo County and then released. The person is at home recovering, the CDC said Saturday.
The best window for recovery is in the first six months after getting COVID-19, with better odds for people whose initial illness was less severe, as well as those who are vaccinated, researchers in the United Kingdom and the United States found
A third dose of COVID-19 vaccine offered essential workers some protection from developing long COVID during Omicron variant predominance, according to a new study in The Journal of Infectious Diseases.
“This case is very concerning for a number of reasons,” says Rick Bright, an American immunologist and vaccine researcher and a U.S. government health official from 2016 to 2020. “It’s in an otherwise healthy teenager. Like a similar case in Missouri, there’s no clear source for infection and no direct farm connection.”
