The recent measles outbreak in the US has raised concerns about vaccination efficacy and boosters. With nearly 500 cases reported across 21 states, health officials are urging parents to vaccinate their children against the highly contagious virus.
According to the Centers for Disease Control and Prevention (CDC), the MMR vaccine is effective against measles, but it’s not a guarantee. Roughly three out of 100 people who’ve received the two-dose vaccination may still contract the virus when exposed.
Those who do get measles after being vaccinated experience milder symptoms and are less likely to spread the disease. However, the risk remains higher for unvaccinated individuals, with 90% contracting the virus if exposed.
Do you need a booster shot? Most vaccinated adults are immune to measles and don’t require a booster. Those born before 1957 may have developed lifelong immunity after contracting the virus at a younger age.
Measles is a highly contagious vaccine-preventable disease that primarily affects children. It’s spread through contact with infected nasal or throat secretions, breathing in the air, or contaminated surfaces. Symptoms include high fever, cough, runny nose, watery eyes, and a distinctive rash.
While vaccination is crucial, understanding measles and its symptoms can help prevent its spread. Parents should prioritize their child’s vaccination schedule to protect against this highly contagious disease.
