Can We Have a Reasonable Discussion on Vaccines?
In a world where opinion is shaped through social media, a public health strategy based on trying to “educate people” by shoving “facts” in their face when the facts are in dispute is not going to work very well. In reality, it may backfire and produce exactly the opposite result from the one you intended. And that is exactly what is happening here.
So what does this mean exactly? Most likely the mumps portion of the MMR vaccine is less effective in the Marshallese population in particular due to some genetic difference in their immune response. It is also possible this virus is “drifting” by changing a protein here or there or an H or N molecule as similar to the influenza virus. So all in all, there are likely small changes in the natural mumps virus altering the landscape for everyone; however those with Marshallese background are naturally more susceptible.
