Measles Vaccination Recommendations in 2025
With measles outbreaks on the rise again in parts of the U.S., it’s more important than ever to make sure you and your family are fully protected. Measles is a highly contagious virus that can cause serious complications, especially in young children and people with weakened immune systems. Thankfully, the MMR vaccine (measles, mumps, and rubella) is highly effective in preventing infection — but are you up to date?
At Homestead Direct Primary Care, we’re here to help you stay informed and protected. Let’s break down the current vaccine recommendations for different groups:
Babies
Under 6 months: Too young for routine MMR. If there’s a known outbreak or international travel planned, a dose may be given early between 6–11 months.
12–15 months: This is when the first routine MMR dose should be given.
4–6 years: The second routine MMR dose is due before starting school.
💡 Traveling abroad? Babies between 6–11 months can receive one early dose, but this won’t count toward the routine two-dose series — they’ll still need two more after age 1.
Children Who've Only Had One Dose
If your child missed their second dose between 4–6 years, it’s not too late! The second MMR can be given at any time, as long as it’s at least 28 days after the first dose.
Full protection against measles is achieved with two doses — one dose is about 93% effective, while two bring that up to 97%.
Adults
If you were born before 1957, you’re generally considered immune because measles circulated widely before the vaccine era.
If you were born in 1957 or later, you need at least one dose of MMR, unless:
You have lab evidence of immunity, or
You had documented measles or received two doses in the past.
📌 Adults at higher risk — like healthcare workers, international travelers, or college students — should have two doses of MMR, at least 28 days apart.
Older Adults Unsure of Their Immunity
Not sure if you’re still immune? Here are your options:
Get a blood test to check your measles antibody levels.
Or, just get vaccinated — it’s safe to get the MMR again, even if you’ve had it before.
💉 There’s no harm in a booster if you’re uncertain — and it’s often easier and faster than testing.
Final Thoughts from Homestead DPC
Measles may seem like a childhood illness of the past, but it’s still very much a present-day threat. The good news? The MMR vaccine is safe, effective, and widely available. If you're unsure about your or your child’s vaccination status, we’re here to review records, order immunity testing if needed, and get you on track with current CDC guidelines.
