Stein, vaccines, and the new, better Green Party
Jill Stein has gotten some negative media attention due to an answer in a Reddit AMA regarding vaccines. Part of her statement:
"I think there’s no question that vaccines have been absolutely critical in ridding us of the scourge of many diseases — smallpox, polio, etc. So vaccines are an invaluable medication," Stein said. "Like any medication, they also should be — what shall we say? -- approved by a regulatory board that people can trust. And I think right now, that is the problem. That people do not trust a Food and Drug Administration, or even the CDC for that matter, where corporate influence and the pharmaceutical industry has a lot of influence.”
followed up later with this, mentioning controversies with the use of hormone replacement for menopause, and treatments for Alzheimer's that backfired:
it's really important that the American public have confidence in our regulatory boards so that all of our medical treatments and medications actually are approved by people who do not have a vested interest in their promotion.
and clarification on Twitter:

Snopes also lists the claim that Stein is anti-vaccination as unproven.
My mother, a psychiatrist, was concerned about Stein's take on vaccines, so I did some research to make sure I had all the needed context.
The Washington Post story, which is the norm among large, nonpartisan media outlets, takes a skeptical look at Stein's claims, assuming that the formal independence of the FDA more or less as true.
The closest Stein gets to anti-vaxx arguments is here:
"There were concerns among physicians about what the vaccination schedule meant, the toxic substances like mercury which used to be rampant in vaccines. There were real questions that needed to be addressed. I think some of them at least have been addressed. I don’t know if all of them have been addressed."
Pretty different from what her remarks were being portrayed as. At its core, Stein doesn't believe that vaccines have any of the purported negative effects that are common currency among anti-vaxxers. Nor does she see any existing issues as overriding the massive public health necessity of vaccination. In fact, she specifically says vaccination rates need to go up in light of Jenny McCarthy and others. As she said on Twitter, the issue is that government agencies have a credibility problem. Even if their statements are 100% true, the intensive lobbying by pharmaceutical companies, and a revolving door between the FDA and private industry, invites skepticism. And indeed that is part of why parents may choose to ignore warnings about things like vaccinations. Even if "the FDA is a tool of Big Pharma" is unrelated to "vaccines are essential for public health," it can muddy the waters.

The pharmaceutical lobby is incredibly powerful. A 2005 piece by the Center for Public Integrity pointed out over $100 million annually in lobbying. To quote, emphasis mine:
The industry's multi-faceted influence campaign has also led to a more industry-friendly regulatory policy at the Food and Drug Administration, the agency that approves its products for sale and most directly oversees drug makers. Most of the industry's political spending paid for federal lobbying. Medicine makers hired about 3,000 lobbyists, more than a third of them former federal officials, to advance their interests before the House, the Senate, the FDA, the Department of Health and Human Services, and other executive branch offices.
A 2015 story in TIME about the now-current head of the FDA, Robert Califf M.D pointed out that he was making six figures in consulting fees annually from pharmaceutical companies. Pharmaceutical companies were instrumental in the passage of Medicare Part D, which is a cash cow because it has no price controls unlike most government health programs. Pharma is also the only part of the health system that was not impacted by the Affordable Care Act, trading perks in exchange for not blocking the bill.
I've been a registered Green from mid-2009 until today, minus the time myself and many others registered independent to vote in the Democratic primary this year. In years past, Green ideology was a complete mess. It was sort of socialist, sort of capitalist, and alternatively enthusiastic about and skeptical of science. Going to a party conference, I was frustrated by the lack of coherence and a tendency towards conspiracy theories and quack medicine.

This election cycle is different, because the primaries have manufactured a large disenchanted bloc of voters who see Stein as an answer. This has had the effect of making Green ideology more consistent, and pushing out its more kooky aspects. An amendment to the 2016 platform was passed by the National Committee to make the Green Party explicitly anti-capitalist and move towards eco-socialism. This would resolve the ambiguous take on economics in Green politics and give the party something to stand on. The party this year also voted to remove support for practices like homeopathy. I do believe that Jill Stein has been part of the solution rather than the problem- her status as a doctor makes outsiders more likely to listen, and since her run in 2012 there has been pressure to move beyond a niche party.
Your vote in November is yours alone. Don't let people bully you into a decision. If you are in a swing state, it's a tough decision and in some sense I'm glad I don't have to make it. If you live in a safe state, a vote for the Greens would be huge. A large result would secure millions in public funding, improve ballot access. Minor parties spend more money on litigation to get on the ballot than anything else. And even if Clinton wins, a 5%+ for Stein shows that the Sanders movement against politics as usual has survived.
Enough is enough. Vote Stein.
