CDC guidance is clear on timing: MMR can help within 72 hours for many people without evidence of immunity, and immune globulin may be an option within 6 days for specific higher-risk situations. Learn what caregivers should watch for at home—plus what families with immunocompromised children should plan with clinicians and public health.
