Measles outbreak caused by recently vaxed person?

[menudo]

Am I reading this right?

The source patient was a student aged 17 years who had received 2 doses of MCV. On March 15, 2003, the student had returned to the United States from Beirut, Lebanon, where measles was known to be circulating. He had cough and fever the following day and rash on March 21, when he visited an emergency department and was diagnosed with a viral exanthem. Upon returning to school, the patient stayed at the school health center before returning to his dormitory.

In the outbreak described in this report, consistent with previous evaluations (10), 2 doses of MCV were highly effective in preventing the spread of measles, although a substantial number of exposed students, combined with a 1% failure rate among recipients with 2 doses, resulted in two generations of transmission in the school. Recipients of 2 doses of MCV had milder symptoms and shorter duration of illness than unvaccinated patients. Two unvaccinated students were hospitalized for dehydration, but none of the vaccinated students required hospitalization

Here is the whole CDC article:

Yet, they keep mentioning 2 girls who caught it were unvaccinated...which makes 11-3=8 vaccinated people infected. If you read it too quickly you'd think they "caused" it...puhlease!!

I read this last week and thought about posting something.

I actually made a couple of other friends read it to make sure I had noted it correctly.
you and I are on the same page.

Very interesting article! It was interesting to read the detail of who was vaccinated and who wasn't, and how unvaxed kids with and without exemptions were handled.

So the person who went to Lebanon and imported the measles had been "adequately" vaccinated. Interesting.

I didn't get the impression that person had been recently vaxed, though. It seemed like they had been vaxed as a child.
