Edited to add: in circumstances such as these, journalists have a solemn duty to get the story right. They need to be educated in science and proficient in science communication. A retraction later is not good enough; silently updating your story without retraction is tantamount to corporate manslaughter in my opinion. As we know from battling online disinformation, people will still be quoting from the original baseless story decades from now.
Get it right or GTFO.
