Les vaccins perdent de leur efficacité au fil du temps, pour diverses raisons. Comment les chercheurs évaluent-ils cette efficacité ? Que sait-on des performances de vaccins actuels contre Omicron ?
For a number of reasons, as time goes on vaccines become less effective. So how do researchers calculate how well vaccines are working?
The risk of getting the coronavirus from a surface is low. But the frequent hand-washing from early in the pandemic is a good thing since most people weren’t washing their hands enough to begin with.
COVID-19 and holiday family gatherings are not a good pair. But taking the right precautions before, during and after the family gets together can greatly reduce coronavirus risk this holiday season.
A recent report by the CDC estimated that the true number of COVID-19 cases in the US could be six to 24 times more than the number of confirmed cases. A public health scholar explains the implications.
The recent spike in new coronavirus cases in the US is not due to a second wave, but simply the virus moving into new populations or surging in places that opened up too soon.
People are turning to quarantine bubbles as a way to see friends and family while limiting the risk from the coronavirus. Research shows that this can work, but it’s not easy to be in a quaranteam.
