Nassau County announced its first confirmed case of monkeypox as vaccines for the virus are being rolled out on Long Island.

Nassau County Executive Bruce Blakeman says residents should not panic because the virus is not as contagious as COVID-19. It is primarily spread through intimate skin-to-skin contact.

"This is not coronavirus - it will never be a pandemic," Blakeman says.

He says the county will still be rolling out the monkeypox vaccine to stop the spread. Nassau has received 400 doses of the vaccine, which will be given out on Monday.

Blakeman says the vaccine centers will be operational at both Nassau University Medical Center and the Northwell HIV Treatment Center.

Suffolk officials are also urging residents not to panic as the county has confirmed three monkeypox cases.

"This is not COVID, and I just want to reassure everybody that it's containable," says Suffolk County Health Commissioner Dr. Gregson Pigott.

Beginning next week, pop-up monkeypox vaccine sites will administer 750 doses in Fire Island Pines and Cherry Grove.

Officials say individuals must meet certain New York state requirements to be eligible for the vaccine.

"Statewide eligibility right now includes individuals with recent exposure to monkeypox within the past 14 days, those at high risk of recent exposure to monkeypox and individuals who've had skin-to-skin contact with someone in a social network experiencing monkeypox activity," says Suffolk County Executive Steve Bellone.

Suffolk officials say they plan to set up vaccine sites on the mainland when they receive more doses from New York.
