“A leading immunologist warned of a ‘post-herd-immunity world,’ as measles outbreaks affect communities with low vaccination rates in the American south-west, Mexico and Canada. The US is enduring the largest measles outbreak in a quarter-century. Centered in west Texas, the measles outbreak has killed two unvaccinated children and one adult and spread to neighboring states including New Mexico and Oklahoma. ‘We’re living in a post-herd-immunity world.
