[Marvel Cinematic Universe] So, about the super soldier serum...

One of the coo things about Captain America is that he's utterly unique.  No one has since been able to recreate the super soldier serum since the 1940s.  Except....they have.  

In The Incredible Hulk, they begin juicing Emil Blonsky with something that essentially makes him a super soldier.  He might not quite be on Cap's level at first, but when he first gets juiced, he is unquestionably a peak human.  

For those saying he turned into The Abomination, that wasn't until *after* he went through a completely different test that he was warned *would turn him into a monster*.  If he, or anyone, simply went through 1 or 2 injections, they would simply remain peak human, with at worst the slightly scary spine thing Blonsky started developing.    And don't forget the serum was still *highly* experimental, so any kinks could still be worked out.  

Point of all this being, have people just forgotten that a working super soldier serum exists?

The serum in Incredible Hulk, while seemingly similar to the Super Soldier Serum is not the same thing.  The "weird spine thing" was not the end all, and while he would not have become a full on Abomination, it probably would not have stopped there.  The serum also seriously messed with his judgement, which is more important.
