Covid vaccines may increase the lifespan of cancer patients – this could be a game changer | Devi Sridhar

A study suggesting mRNA vaccines help the body fight malignant cells raises the tantalising prospect of a low-cost, low-risk treatment that could help with all cancersI’m often asked whether we’re better prepared for the next pandemic. It’s a mixed answer, but the bright spot is scientific progress on vaccines. The Covid vaccines were produced faster than any previous effort, and are credited with saving millions of lives from 2021 onwards. The mRNA vaccines – Pfizer/BioNTech and Moderna – were designed within days of the Sars-CoV-2 genome being published in January 2020, and went into safety trials over the following months before finally being approved in the UK at the end of 2020.But could they have additional benefits? According to a recent study published in Nature, mRNA vaccines seem to trigger a powerful immune response that increases the median survival time by about 75% for certain cancer patients. These findings – which are being further developed – could indicate the power of repurposing vaccines and medicines that have already passed trials for safety and are available at reasonable cost.Prof Devi Sridhar is chair of global public health at the University of EdinburghFit Forever: Wellness for midlife and beyond.
