Great Neck resident Agota Adler, 85, has beaten hardships before, having survived the Holocaust in Hungary and then fleeing the communist regime that followed the war. She immigrated twice, to Brazil and then to New York. She eagerly signed up for her coronavirus vaccine, but last week’s snowfall and the difficulty of obtaining a ride to the hospital was resolved by young volunteers who drove Adler to her appointment. “Chaverim took me from my home to the hospital in Queens, where I was vaccinated. I did not feel any pain,” Adler said.
