Israel got priority by being 'just right' sized with an efficient healthcare system and being able to demonstrate the ability to organise a mass vaccination as quickly as possible. As such they acted as a very large scale test of what we can expect as the number of people vaccinated increases. I don't think this is particularly to the detriment of Germany. Wasn't Israel vaccinating people before Germany had approved any vaccination?
