Dr. Frank Esper works for the Cleveland Clinic Children s Hospital.
He said as COVID-19 vaccines are made available to more people across the country, we re beginning to work toward herd immunity.
What is herd immunity? A doctor explains how the coronavirus vaccine can help stop the virus spread.
Herd immunity happens when there s enough protection in the community to prevent continued spread of the virus, Esper said. When you see a high percentage of people who are immune to a germ, then that germ is not able to spread so quickly through the community. It s finding roadblocks because people are immune, he said. If the virus comes to you and you have immunity against it, that s a dead end for that virus. That virus has been blocked from spreading.
When it comes to protecting against the novel coronavirus, are two face masks better than one?
While face masks have proven to tamp down on droplet spread, including harmful, virus-laden particles, questions remain if doubling up on masks could boost protection, with several experts chiming into the debate.
Those who spoke to Fox News said there’s little to no evidence to sway the issue in either direction, though some may disagree. There are no data to support (or refute) the idea that wearing two face masks would provide more protection against coronavirus, Dr. Dean Winslow, infectious disease expert at Stanford Health Care, wrote in an email.

Nearly 60% of all new coronavirus cases may come from people who carry the virus but who exhibit no symptoms of Covid-19, according to a new
CDC model findings experts say are even more concerning in light of a new, more contagious variant of the virus that s emerged.
For the model, published in
JAMA Network Open, researchers at CDC looked at data from a number of Covid-19 studies from last year, which they used to establish several baseline assumptions. For example, the researchers presumed that 30% of individuals who contract the new coronavirus never develop symptoms but remain 75% as infectious as those who do develop symptoms.
