State lawmakers are growing increasingly frustrated with the rollout of the COVID-19 vaccine amid a lack of supply from the federal government and scheduling mishaps.

A bipartisan group of lawmakers on Friday in the Hudson Valley released a joint statement raising concerns they have heard from constituents over the distribution -- the confusion, the lack of doses and the problems with accessing websites to schedule a vaccination appointment.

The statement, released by Democratic Sen. Elijah Reichlin-Melnick, Democratic Assemblyman Ken Zebrowski and Republican Assemblyman Michael Lawler, all of the Hudson Valley, reflected the increasing concern among lawmakers over the distribution.

"We are deeply concerned with the current distribution process for delivering the COVID vaccine. A lack of transparency and clear guidance has created unnecessary panic and frustration for our constituents," the lawmakers said.

"The federal government’s failure to supply New York State with sufficient vaccine doses to cover essential workers and seniors has created this problem, but while we wait for more doses to arrive, the process for scheduling appointments must be standardized and made much more transparent. It is unacceptable that seniors must spend hours of their day calling around to different locations - only to hear busy signals, receive conflicting information, or to hear that all appointments are booked and no more appointments are being accepted."

New York on Friday began to open additional mass vaccination sites, including one at the University at Albany campus and other public colleges around the state. 

Still, the lack of supply of doses for the vaccine has struggled to keep with the demand. If appointments can be made, they can take up to 14 weeks for a shot to get into a New Yorker's arm.

Sen. Gustavo Rivera, the chairman of the Senate Health Committee, earlier this week blasted the distribution of the vaccine so far, saying he was "appalled" by the problems.
