Actually, tarrifs on drugs is not such a bad thing. Imported drugs have been shown to have higher levels of contaminants (toxic metals, arsenic, and etc) than domestically produced drugs. Especially when given to children the effects can be disastrous.
And these contaminants also have a strong link for being a culprit in triggering autism in children.
Meaning it could be that these vaccines, made in India are not harmful in themselves, but the contamination and poor controls over their manufacture are responsible for the autism epidemic.
So....I'd let this one alone.
