Once you've had COVID-19 and recovered, are you now immune from the virus? There's still no clear answer, but the experts share their perspectives:
That's the critical question that will help shape how the United States re-opens for business in the coming months.It's still too soon to tell if the first wave of COVID-19 survivors will remain immune to the virus for any appreciable length of time.
"With the four seasonal beta coronaviruses that circulate and cause all the upper respiratory infections you see in your practice, those people lose immunity in months to a year or two," Poland said. That's why people fall prey to the common cold again and again. However, other patients who did not develop serious infections did not gain high levels of MERS-specific antibodies, making any immunity potentially short-lived, the report said.But early animal research that hasn't yet been peer-reviewed shows that antibodies in rhesus monkeys that had COVID-19 protected them from becoming infected when exposed again to the virus, Chinese scientists reported on the website BioRxiv.
