After the Vatican Council II closed, the Popes started to implement the changes that were asked for by the Council. They are still in the process of that in the early 21st century, and will be at it for another fifty years. The Church doesn't move on the same time schedule as the modern world.
We are still waiting for this to happen. It usually takes decades to fully implement a Council, and this hasn't yet happened with Vatican II.

In Vatican City, thus the name Vatican Council II.
There were exactly no doctrines defined at the Second Vatican Council. The Second Vatican Council was the first purely pastoral council ever held in the Church.

It has been fifty years since the Council issued its last document, and the sad truth is that it is just now starting to be implemented. Most of the things that have happened in the past fifty years were NOT called for by the Council, but were done in the "spirit of Vatican II". The current Holy Father, and his two predecessors have made it abundantly clear that most of the things done in the "spirit of Vatican II" were wrong.
