A new study shows that Covid-19 vaccines don't impair fertility in men or women — but a Covid infection could potentially affect a man's fertility for up to 60 days. Research funded by the National Institutes of Health and published on Thursday in the American Journal of Epidemiology tracked data from more than 2,100 women and some of their partners in the U.S. and Canada for roughly a year, ending in November 2021. It found that getting vaccinated against Covid had no discernable effects on fertility rates in either men or women, adding to a growing body of evidence regarding the safety of Covid vaccines. The study also found that men who tested positive for Covid within 60 days of their partner's menstrual cycle were 18% less likely to conceive during that cycle, compared ...

(CNN) — Kris Sokolowski has always been active, spending his free time mountain climbing, running and practicing martial arts.

And it just wasn't going away for a couple of days," he tells CNN Tra...

Booster shots of the Pfizer-BioNTech and Moderna vaccines have proven highly effective at preventing Omicron-related hospitalisations, according to three new studies by the US Centers for Disease Control and Prevention. The booster doses were 90 percent effective at keeping people out of hospital after they had become infected with the Omicron variant. The doses were also 82 percent effective at preventing emergency department and urgent care visits, data indicated. “It really shows the importance of getting a booster dose,” the CDC’s Emma Accorsi, one of the study’s authors, said on Friday. “Americans should get boosters if at least five months have passed since they com...
