From the Palermo tragedy to the melanoma vaccine: Vaia, "Science saves lives."

The tragedy of the four-year-old girl who died in Palermo's Zen neighborhood has reignited the debate on prevention and trust in science. This debate, according to Francesco Vaia, former Director General of Prevention at the Ministry of Health and Director General of the Spallanzani Institute, must begin, first and foremost, with respect for a family affected by such profound grief.

"Before any other consideration comes respect for a child who is no longer with us and for a family experiencing unspeakable pain," Vaia emphasizes, urging that this matter not be turned into a trial against the parents.
"The investigations will clarify what happened."

According to the former Director General of Prevention, medical checks and ongoing investigations will definitively establish the cause and circumstances of death. Beyond the individual case, however, the story calls for a broader reflection on the value of vaccinations and the effects of health misinformation.

"Vaccines have saved millions of lives and made rare diseases that for generations killed or left severely disabled, especially children," says Vaia.

For the doctor, vaccination cannot become a battleground for political or ideological conflict. "Vaccines, and especially their correct use, remain one of the most effective public health tools," he reiterates.

The alarm about online disinformation

The focus is particularly on content shared on social media without solid scientific basis. Vaia criticizes those who fuel fears and doubts about vaccines by leveraging information lacking consolidated evidence.

Health misinformation, he emphasizes, "is neither neutral nor harmless": it can influence people's choices, encourage them to forgo vaccination, and reduce both individual and collective protection.
An even greater responsibility, according to Vaia, falls on those who work in the medical and healthcare world and contribute to the dissemination of information without scientific basis.

From the preventive vaccine to the one against melanoma

The paradox Vaia points out is that, just as mistrust of vaccines is growing, scientific research is greatly expanding their potential.

The reference is to the results of the personalized mRNA therapeutic vaccine against melanoma developed by Moderna and Merck. Combined with immunotherapy, the treatment demonstrated a significant benefit in reducing the risk of disease recurrence or spread in the Phase 3 study.

A prospect that could open new frontiers in the fight against cancer. Vaia also cites the work of Paolo Ascierto, one of the leading international experts on melanoma, calling the results "extremely significant."

The research, he emphasizes, must of course complete its evaluation process, but the results confirm the value of investing in science and innovative medicine.

"Frightened citizens must be listened to."

Vaia finally distinguishes between those who express doubts and those who, instead, knowingly spread false information.
"Novaxism isn't fought by insulting people, but by explaining, communicating well, and providing clear scientific evidence," he observes. The debate, therefore, must begin with listening and the ability to communicate the available data in an understandable way.

According to the doctor, the situation is different for those who build consensus and visibility by deliberately distorting scientific evidence. "Words can have serious consequences," he warns.

"Science thrives on doubt; it cannot be demonized."

Vaia's conclusion is a plea to defend the scientific method without turning it into dogma: "Science must be discussed, verified, and improved because it feeds on doubt, but it cannot be demonized or exploited by political parties."

The key, for the former health director, remains rebuilding a relationship of trust between citizens, medicine, and research. Because, he concludes, "good science saves lives; misinformation can contribute to losing them."
