As the nationwide demand for COVID-19 vaccines drops, several communities in New Jersey are dropping appointment requirements and allowing walk-ins.

Between 20-30 people were seen lined up Sunday morning outside the El Centro Catholic Church in Trenton.

Lines of people were also seen on the campus of Sacred Heart Church, where 500 Moderna vaccines were administered.

"I have a lot of people who were trying to make appointments with CVS and all the other appointments they were given out but there was no luck," said Yaritza Gudiel, of Mercer County.

The city will also be hosting walk-up events on April 29 and April 30 from 5 p.m. to 9 p.m. for those who can't get off of work so that they also have access.

"We have noticed that in Trenton," said Maria Richardson, the chief planner of Trenton's COVID response team. "We attribute that to more than one factor. The fact that the Johnson & Johnson vaccine was halted had created a lot of anxiety among people that were ready to get vaccinated and now they are hesitant. But also, because we have done a great effort in vaccinating people."

Nearly 2.8 million New Jersey residents have already been vaccinated, and at least 57% of Mercer County adults have received at least one dose - causing a decline in the demand. Gov. Phil Murphy hopes to fully vaccinate 4.7 million New Jersey residents by June 30.
