A Christmas tree made of approximately 19,000 used COVID-19 vaccine vials was displayed at the vaccination center of the Children’s Palace in Bucharest, Romania’s capital. The tree stands 3 meters tall and has a diameter of 2.2 meters. The preparations for this Christmas tree began on March 1st, when the vaccination center in the Children’s Palace opened. Before being used to form a Christmas tree by center staff a month ago, all of the used vials were stored in a safe room.
