"... The mysterious incidents,

May ???   Have been. ????

Iranian authorities need to take a page out of the USA stealth government  Book.

On how to LIE to it's populous,
when they introduce a, 'must have', vaccine,
that is designed to control the Citizens.

The comments come as Iranians officials in recent weeks have begun to acknowledge the poisonings, which started last year and have caused hundreds of schoolgirls across the country to fall ill.

The attacks have so far affected over 50 schools and more than 400 schoolgirls in 21 provinces across Iran, with some politicians placing blame on religious extremist groups opposed to girls' education.

This was much worse than I expected.
