Officials say county-run vaccination sites are only delivering second doses of the coronavirus vaccine today as first doses have been delayed due to winter weather.

Sites like the Yes We Can Community Center in Nassau County have not yet received new first doses of the coronavirus vaccine. The same problem is happening at sites in Suffolk County.

Facilities are reopened after two days of closure, but vaccinations are not back running in full due to those delivery delays because of weather across the country.

Some senior citizens in Long Island say they have still not been able to make appointments for their first dose of the vaccine.

Hicksville resident Susan Smith says it’s frustrating to still be waiting after being eligible.

“I think it’s terrible,” Smith says. “They should be getting it to us. The president says by the end of July, it’s a long way off, especially for us older people.”

Gov. Andrew Cuomo says the delayed vaccine should start arriving at the beginning of next week.

White House coronavirus adviser Andy Slavitt says they are ensuring that the vaccines are not spoiling.

“The vaccines are sitting safe and sound in factories and hubs ready to be shipped out as soon as the weather allows,” Slavitt says.

Nassau County officials say vaccinations at county-run sites scheduled for Thursday or Friday will now be taking place on Monday.

Those with appointments should check their email for a link to reschedule.
