COVID-19 Vaccination Information and Resources

Mount Sinai Health System will pause the administration of the Johnson & Johnson vaccine in accordance with recommendations by New York State, CDC and FDA due to extremely rare, adverse events related to the vaccine. All Mount Sinai South Nassau vaccination van events will use the Pfizer vaccine for the time being. People who have received the Johnson & Johnson vaccine who develop severe headache, abdominal pain, leg pain, or shortness of breath within three weeks after vaccination should contact their health care provider. We will provide more information when available.

At this time, we regret that we are unable to take requests for new vaccination appointments. As our vaccine supply permits, we are reaching out to eligible patients and community members to schedule appointments. If you are looking to book a vaccine appointment, please consider vaccination options through New York State and New York City. All second-dose and employee vaccinations are proceeding as scheduled. For more information, visit our Vaccine Appointment Information page.

As of Tuesday, April 6, all residents of New York State ages 16 and over are eligible for COVID-19 vaccination.

There are a lot of myths on the internet about COVID-19 vaccines. Mount Sinai is working with a company called NewsGuard to provide the most accurate information. If you’ve heard something that sounds questionable and want to know if it’s true or not, you can look it up in NewsGuard’s report on the top COVID-19 vaccine myths.

If you received Dose 1 from Mount Sinai and are scheduled to receive Dose 2, we encourage you to keep your appointment. However, if you:

  • Need to reschedule due to an emergency
  • Believe your Dose 2 appointment was canceled in error

Please call us at 646-605-5760. This line is NOT for general questions about the vaccine or new appointments.
