That trials were sped up is not nonsense as that is exactly what happened. You disagree it compromised safety but that doesn’t change you were wrong as the other poster pointed out to you. It went against industry norms to get a vaccine out as soon as possible: that an overlap of trials is considered equally safe by some is irrelevant to that point.

Regardless, you did not argue against the posters main point but instead chose to push back against what you thought would be an easy win and you did so with a factually incorrect rebuttal.
