1 year old had mmr vaccine 11 days ago, little dot rash over body and a large pea sized lump at nape of neck hairline can't see doctor for a week?

Common finding: This is a common finding in many kids who receive the MMR. It is a sign the weakened virus in the vaccine did its job well and the kid had a minor rash in response.The real thing would have been 20X worse. The lump is a reactive lymph node and will reduce in size within 2-3 wks.You might call the office to have the experience recorded in the chart, but I wouldn't worry about going in.
