People who are vaccinated or who take Paxlovid during a Covid-19 infection have a lower risk of developing long Covid, new research shows.
The US Centers for Disease Control and Prevention defines long Covid as new, returning or ongoing health issues more than four weeks after an initial infection. According to the CDC, 1 in 5 Covid-19 survivors ages 18 to 64 and 1 in 4 survivors 65 or older have an ongoing health issue that might be attributable to Covid-19 infection.
A study published Thursday in JAMA Internal Medicine analyzed data from 41 studies, including more 860,000 people around the world. Of the four studies with vaccination information of nearly 250,000 people, those who had been vaccinated against Covid-19 had almost half the risk of long Covid than people who weren’t vaccinated.
