Then they are not a threat.
Measles start 4 days before the rash appears and travel through the air. Obviously keeping them home from school does not factor into this. Then again, vaccinated children don't need to miss school.
Vaccinated children might prefer to be exposed, since their wild measles infections, etc, would (for most of them, not all) be asymptomatic.
Nevertheless, I would keep my kids home, symptoms or not, until the 4 day incubation period passed, just in case they caught something.
That way my kids couldn't spread it, whether they became symptomatic or not. Meanwhile, vaccinated kids will spread it without realizing they are a risk.
The exposure starts BEFORE the rash. I thought you knew everything about his *harmless* disease. :think:
It just shows you assumed before asking.
And since you were clueless about transmission in vaccinated populations:
China has measles despite 99.9% compliance. It's not the fault of the 0.01% either. A full 3% cannot be protected no matter how many shots they get. They will spread it and make other students sick before they even know what has happened.
Then unvaccinated children will be blamed if they show signs of exposure to that vaccinated child.
Since they are mandatory, it would be without.
And that's wrong. It's plainly discrimination against healthy, organic lifestyles. You don't have to use a vaccine to control the spread of disease.
Exclusion from private and public schools is the only viable option for those who do not care about the health of those children attending these schools.
Labeling them as not caring doesn't justify it. Sick children shouldn't be in school. That's how you protect the immune compromised. You can't stop the schoolchildren from spreading sickness with vaccines.
