A vaccinated resident of St. Louis County has contracted a rare case of measles, as reported by FOX 2.
St. Louis, MO, September 21, 2026 — A resident of St. Louis County who has been vaccinated against measles has contracted the illness, according to a report from FOX 2. The case is described as rare.
Details surrounding the specific circumstances of the infection and the individual’s vaccination history were not immediately available. Measles is a highly contagious viral illness that typically spreads through respiratory droplets when an infected person coughs or sneezes.
The Centers for Disease Control and Prevention (CDC) recommends vaccination as the most effective way to prevent measles. The measles, mumps, and rubella (MMR) vaccine is routinely given to children in two doses, and it is also recommended for adults who may not have been vaccinated or have not had the illness.
While vaccination significantly reduces the risk of contracting measles, extremely rare instances of breakthrough infections can occur. The exact factors contributing to such rare cases are often complex and can depend on various elements, including the specific vaccine, the individual’s immune system response, and the level of exposure to the virus.
Information regarding any potential public health responses, contact tracing, or further details from the FOX 2 report was not provided in the summary. The contractor’s name was not provided.
