A growing measles outbreak in the US has raised concerns about vaccination rates and protection against the highly contagious disease. As of March 12, Texas and New Mexico reported over 250 cases, with two deaths linked to unvaccinated individuals.
According to experts, when vaccination rates drop below a certain threshold (95% or higher), outbreaks can occur. The measles, mumps, and rubella (MMR) vaccine is highly effective against the disease, with 93-97% effectiveness after one or two doses.
Those in proximity to the outbreak should ensure they have been vaccinated, especially if they have not had measles or were born before 1957. Adults who have received only one or two doses of the MMR vaccine may need a booster shot. The Centers for Disease Control and Prevention (CDC) recommends vaccination for certain groups, including healthcare workers, students, and travelers to high-risk areas.
Measles is extremely contagious and can spread beyond the epicenter of an outbreak. However, sporadic cases outside of unvaccinated communities are unlikely to lead to new outbreaks.
Key takeaways include: measles can cause severe disease and be fatal, and the MMR vaccine is safe and effective in preventing it.
