What has been your experience with the operation of the New York City (and other) vaccination centers.
Mine was excellent. I was in and out in about 20 minutes (not counting the post-vaccination waiting time to check for adverse side effects). The staff were courteous, friendly, and very helpful. If your paperwork was not quite right, they had alternative ways of checking on your eligibility, which they did readily and promptly. Under very difficult circumstances, it could not have been better.
