Thousands waited in the rain Saturday for their shot at getting a COVID-19 vaccine outside the pop-up site at Elmont Memorial High School.

The site was the latest to focus on a community of color hit hard during the pandemic.

Nassau officials teamed up with Northwell Health to run the site and with neighborhood leaders to get the word out.

There were a total of 1,000 appointments, which did not last long.

“You can imagine 1,000 appointments get taken up very quickly,” says Nassau County Executive Laura Curran. “There's such a demand, there's such a need for this vaccine.”

More doses will likely be available at distribution sites now that the FDA has granted emergency use authorization to Johnson & Johnson's vaccine, which only requires one shot.

County officials say they don't know how many doses they will get next week. However, they say more than 1,000 volunteers, doctors and nurses are ready to administer them.

Another pop-up site is being planned in Glen Cove.

“I'm going to stay positive that I think we are going to have a relatively normal summer, based on the fact that we can vaccinate the overwhelming majority of the community,” says Dr. Lawrence Eisenstein, Nassau’s health commissioner.

Soon, Nassau County will be able to add senior citizens to the list of people they can vaccinate after getting approval from the state. Previously, the county was only allowed to vaccinate essential workers and people with comorbidities.
