There is more help for vulnerable seniors in Nassau County to get a COVID-19 vaccine.

Many seniors have told News 12 their stories of struggling with the online reservation system, saying it is difficult to navigate and sometimes state phone lines are overwhelmed. Now Nassau County is trying to ease the struggle.

Nassau launched its own dedicated call center Thursday to help seniors with coronavirus questions and booking vaccine appointments.

The hotline is 516-227-9590. It is staffed seven days a week from 9 a.m. to 4:45 p.m.

According to state data, 14.4% of Long Islanders have been fully vaccinated. Many of those are seniors, but doctors say it's not enough and are encouraging all seniors to get an appointment.

"We are seeing that the people who are getting the sickest are those who have the least reserve, and that tends to be senior citizens," says Northwell Health's Dr. Adam Berman.

Nassau County's senior coronavirus hotline is being run through the Department of Social Services in Uniondale, and officials say they'll be able to answer calls in multiple languages.

Suffolk County says it has a similar service through its 311 information line.
