Can anyone tell me the name of this alien movie I am describing?

The aliens have a hive ship they leave in orbit and send smaller (round) transport ships to the surface. They want the Earth but they are willing to relocate humanity to another world, so they say. So, many people start boarding their transports and go to the hive ship where, it turns out, they are drained of their blood. The aliens then expel the bodies into space before the transport ships return to earth for another load. In the movie, the American president is a woman. She has a son who has some type of disease. The aliens try to win her confidence by curing the boy. In the end, the president infects the hive queen with a virus and humanity is saved. This is a recent movie, perhaps as late as 2017.
