Hi all.
I just came across this article.
http://www.health.gov.au/internet/main/publishing.nsf/content/cda-cdi3302k.htm
Routine surveillance following an outbreak. Here's some quotes...
"The number of vaccine doses was known for 57 of the 78 cases, of which none had received 2 doses of a MCV, four (7%) had received 1 dose and 53 (93%) had received no doses: the remaining 21 cases were of unknown vaccination status (Figure 3)"
and
"Queensland had a total of 31 cases of measles notified in the 1st quarter of 2009. Of these, 25 cases in a Sunshine Coast high school were linked to an imported case from India diagnosed on 12 January 2009, and were of genotype D4. None of the 25 cases were vaccinated at the time of exposure. In this case an outbreak occurred amongst a cohort of unvaccinated children despite the vaccination coverage in the overall geographical area being estimated at greater than 90%"
So what does this suggest to us? If you're not vaccinated, you're more likely to get measles in an outbreak. Also, if vaccination rates decrease further, outbreaks are more likely to occur.
Can anyone at AVN explain these findings in a plausible manner?
