Measles Outbreak in MN Shows King County is Vulnerable, Too

Vaccines have made a huge impact in protecting us from preventable diseases. But in some communities, immunization rates have dropped dramatically, creating the opportunity for diseases to return. A current outbreak in Minnesota shows what could happen in Washington.
Hennepin County in Minnesota is in the midst of a large outbreak of measles which is primarily affecting the Somali community there. There are over 60 cases at this point in time and the count is expected to rise because vaccination rates against measles in that community have plummeted from 92% in 2004 to just 42% in 2014. Measles is highly contagious and vaccination rates need to be well over 90% to prevent the spread of this horrible disease. It appears that the community was misinformed about the risks and benefits of measles vaccine by anti-vaccine celebrity Andrew Wakefield* who visited there on several occasions. Even in the face of overwhelming evidence based medicine showing vaccines are safe and effective, pediatricians and family physicians are confronted every day with parents who question vaccine safety and delay, defer or refuse one or more recommended vaccines.
Vaccine advocates are concerned about families who delay or decline vaccination because of outbreaks like the one currently active in Minnesota. With similar pockets of low immunization rates and regular measles exposures, King County is vulnerable to a similar outbreak. Although measles is much more likely to affect those unimmunized by choice, the vaccine is not 100% effective and measles can occur in a small percentage of people who did the right thing and got their vaccine. Also, there are those who are unimmunized because of medical condition or age since the vaccine is not recommended until 1 year of age.
First and foremost, vaccines protect those who receive them. But receiving vaccines in many cases also helps to protect your family, friends and neighbors from disease as well. Talk to your doctor about keeping up to date in child and adult vaccinations (yes, adults need vaccines too). If everyone eligible for vaccines got immunized, we would be a healthier community.
*For those who don’t know, Andrew Wakefield is the researcher from the United Kingdom who tried to link MMR (measles, mumps and rubella) vaccine and autism. But his research has been discredited and his medical license revoked. Extensive research has shown that there is no link between vaccines and autism. Leading autism advocates including Alison Singer, president of the Autism Science Foundation have concluded that vaccines do not cause autism.
