Personalized mRNA cancer vaccines (targeting tumour antigens) can sensitise tumours to Immune checkpoint inhibitors (ICIs). This makes them more receptive to the latest immunotherapy breakthroughs in treating cancers.
Personalized mRNA cancer vaccines are still very expensive. What this research has found, is that existing mRNA vaccines for unrelated things like Covid, have some of the same effect. The effect was significant and happened with lung and skin cancers. The researchers theorise it may broadly work for all cancers treated with immunotherapy.
Sadly, we still haven't cured misinformation with the same success rate. In some countries, people trapped in disinformation media bubbles won't benefit from these new lower rates of cancer.
