Measles cases are rising nationwide, prompting parents to vaccinate their children. As of Tuesday, over 160 people have contracted measles in at least eight states. While vaccination is highly effective, there are some things to know about measles and the MMR vaccine.
Can you get measles if you’ve been vaccinated? Yes, but it’s rare. About three out of 100 vaccinated individuals may contract the virus when exposed. Their symptoms are milder than those who haven’t been vaccinated, and they’re less likely to spread the disease.
The Centers for Disease Control and Prevention (CDC) reports that one dose of the MMR vaccine is 93% effective against measles, while two doses provide 97% protection. Most adults are immune to measles after receiving the initial vaccination series, but a booster shot may not be necessary for those who received the full series.
Measles is caused by a virus that primarily affects children and spreads through respiratory droplets when an infected person coughs or sneezes. The disease can cause symptoms like high fever, runny nose, watery eyes, and a distinctive rash. In severe cases, measles can lead to hospitalization for unvaccinated individuals.
Key facts:
– 90% of unvaccinated people exposed to measles contract the virus.
– Measles is highly contagious and airborne.
– The MMR vaccine is effective against measles, mumps, and rubella.
– Seniors born before 1957 likely developed lifelong immunity after contracting measles.
