Evidence review finds aluminum-adjuvant vaccines not tied to autism, asthma or type 1 diabetes

Current evidence does not support direct (causal) associations between aluminum-adjuvant vaccines and serious or long-term health outcomes, including autism, diabetes and asthma, finds a review of the latest data published by The BMJ.
Current evidence from randomized controlled trials and large observational studies shows no causal association between aluminum-adjuvant vaccines and serious or long-term health outcomes, including autism, type 1 diabetes, asthma, or myalgia. The most common adverse reactions are rare, localized, and self-limited injection site nodules or granulomas.
Small amounts of aluminum salts (adjuvants) are commonly used in vaccines against diphtheria, tetanus, pertussis (whooping cough), hepatitis, HPV, and meningitis to make them more effective and longer-lasting. Yet, despite a decades-long safety record, questions about potential long-term effects continue to arise in scientific and public settings.

To address this, researchers searched scientific databases to identify randomized controlled trials and observational studies published up to 27 November 2025 that assessed health outcomes after exposure to aluminum adjuvants included in vaccines.

They found 59 eligible studies that investigated a range of outcomes including autism, asthma, headache, muscle pain (myalgia), and skin reactions (nodules and granulomas) at the injection site. Studies of investigational vaccines were excluded, as their findings are not directly applicable to existing immunization programs.

The studies were of varying quality, but the researchers were able to assess their risk of bias and certainty of evidence using established tools.

High quality evidence from randomized controlled trials and large observational studies consistently showed no association between aluminum-adjuvanted vaccines and health outcomes, including autism, type 1 diabetes, asthma, and myalgia.
The most consistently documented reactions were persistent nodules or granulomas at the injection site, but they were uncommon, local, and self-limited.

The 'nostalgia effect': Scientists produce less disruptive work as they age
As scientists age, their work shifts from producing disruptive innovations to creating novel combinations of existing ideas, with a tendency to cite older research. This "nostalgia effect" is transmitted through academic hierarchies, influencing younger researchers and shaping the direction of entire fields and nations. Countries with younger research communities generate more disruptive science, highlighting the importance of balancing continuity with the influx of new ideas.

Anaesthetized people can process words

A deep brain structure called the hippocampus can learn and process language even when a person is under general anaesthesia. A probe that can record the activity of individual neurons in real time detected the region responding to the speech in a podcast and learning how to differentiate different tones. That doesn’t mean anaesthetized people are ‘secretly awake’ — just that this one structure, the hippocampus, computes and integrates information even under anaesthesia.
