The world might be facing a "post-herd immunity" era for measles. This is a scary thought.  In recent times, measles has been popping up in places with low vaccination rates. This includes parts of the American south-west, Mexico, and Canada.  The United States is currently experiencing its largest measles outbreak in 25 years.  The outbreak started in west Texas and has spread to neighboring states like New Mexico and Oklahoma. Sadly, two young children and one adult who were not vaccinated have died.

        There is a big problem with measles.  It is extremely contagious.  It is more contagious than any other vaccine-preventable disease.  This makes it the first to come back when vaccination rates drop.  The United States had eliminated measles in 2000.  But now, there are 935 confirmed cases across 30 states.  Nearly one in three children under five involved in the outbreak have been hospitalized.  This is a big deal.  The risk of measles is high in the Americas and has increased 11 times compared to 2024.

        Measles cases have also surged in Europe.  In 2024, there were ten times more cases than in 2023.  Most of these cases were in Romania.  This spike is due to a drop in vaccine rates.  Only three countries in Europe have high enough vaccination rates to prevent outbreaks.  The measles virus is spreading from country to country.  Many cases are in areas with large Mennonite communities.  These communities have a history of moving through the American south-west, Mexico, and Canada.  Mennonite teachings do not ban vaccines.  But some in the community may have limited contact with health authorities, leading to lower vaccination rates.

        The current health secretary, Robert F Kennedy Jr, has been spreading false information about vaccines.  This is worrying.  He has made false claims about the measles vaccine.  He has also promoted unproven treatments for measles.  The scientific consensus is clear: the best way to prevent measles is through vaccination.  Measles is a serious disease that can kill or cause lifelong disabilities.  It is not easily treated.  Vaccination has saved millions of lives worldwide.

        The National Institutes of Health is launching a trial for a "universal" influenza vaccine.  This is good news.  But the administration's hostility toward Covid-19 vaccines is concerning.  Experts fear that the rate of infection for diseases like measles will increase.  This is due to the spread of misinformation and the undermining of public health infrastructure.  It is crucial to promote vaccination and prevent the spread of false information.  The health of communities depends on it.
