What if we stop vaccinating? Doctor explains how quickly diseases can relapse

Vaccines are one of the greatest, most affordable weapons in contemporary medicine, yet their reach is underappreciated. We now have vaccines that prevent over 30 potentially fatal diseases and enable individuals of all ages to live healthier, longer lives. According to the World Health Organisation (WHO), immunisation prevents between 3.5 and 5 million deaths each year from illnesses like measles, diphtheria, tetanus, pertussis (whooping cough), and influenza. But what if this life-saving shield were suddenly removed? The consequences would be swift, severe, and far-reaching.
