Which vaccine was falsely linked to autism in 1998?

Explanation:
A mistaken link emerged in 1998 between a combined measles, mumps and rubella vaccine and autism. This specific vaccine, known as the MMR, was the one implicated in that controversial claim. The study that made the connection was later found to have serious methodological flaws and undeclared conflicts of interest, and it was fully retracted with the lead author stripped of his medical license. Large, well-conducted studies since then have found no evidence that the MMR vaccine causes autism. The incident serves as a historic reminder of how fragile trust can be when claims aren’t solidly supported by evidence, and it underscores the importance of ethics and rigorous science in public health. Other vaccines like DTP, Hib, or Varicella were not the focus of this particular controversy.
