The country's top infection disease expert is giving his approval for families to gather for Thanksgiving if they are vaccinated.

Dr. Anthony Fauci says cases are still high and people should wear a mask when they are out in the community and around groups of people in indoor settings.

"If you get vaccinated and your family's vaccinated, you can feel good about enjoying a typical Thanksgiving, Christmas with your family and close friends," Fauci says.

Chief of Infection Disease at Northwell Health Dr. Bruce Farber says he hopes people will listen to Dr. Fauci's conditions for holiday gatherings.

"I don't know whether people will listen," Farber says. "Some people will, and many people won't and that's up to them, you know, it's their individual right to do what they want."

Some Long Islanders say there is a little fear of breakthrough cases, while others say they are not worried at all.

"I think they're making people crazy," says Plainview resident Gig Properzio. "That's what they're doing, they're making everybody nuts."

Doctors say they are concerned about a post-holiday surge in COVID-19 cases and some are urging people to get the booster shots as soon as they can.
