The nationwide experiment will initially include around 100,000 volunteers.
A US government website for collecting reports of side effects associated with vaccines is broken. Why has no one noticed?

ISTOCK, GOROVITSEverything in science involves uncertainty. And for drugs and vaccines, “pharmacovigilance” helps researchers and patients navigate this uncertainty by gathering and processing information on the side effects of medical products in the post-marketing period. Clinical trials conducted prior to approval are often small (median 760 people) and quick (median 14 weeks), making it a challenge to pick up serious but rare or latent side effects of medicines. (And even if researchers capture rare adverse events, determining causality is difficult.)
Active post-marketing surveillance therefore is our safety net, and in the United States, the Centers for Disease Control and Prevention (CDC) and Food and Drug Administration (FDA) run a pharmacovigilance program for vaccines known as the Vaccine Adverse Event Reporting System (VAERS).
But if you use Chrome, Firefox, or Internet Explorer to browse the Web, chances are you will get an error page when trying to connect to the VAERS website: www.vaers.hhs.gov. “Your connection is not secure,” my browser tells me. “The owner of www.vaers.hhs.gov has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.”
If this were a temporary problem, it would not be worth writing about. But I first alerted officials about the problem a month ago on April 25. When the problem persisted for three more weeks, I decided to write about it for The BMJ, where I work. The website remains misconfigured today, on day 28 (at least; I only know when I discovered the problem, not when the problem actually started).
PETER DOSHIMaking sense of the problem
I have long felt that our systems of collecting credible scientific information about a drug’s benefits and harms post-marketing were woefully inadequate. Recent research bears this out. Few drugs are studied in controlled trials post-approval, the majority of post-marketing studies planned are too small to detect rare, adverse events, and many planned studies take far too long to actually commence. What is more, VAERS and the equivalent system for drugs, FAERS, are spontaneous reporting systems—it is estimated that, at most, 10 percent of actual adverse events get reported.
FDA declares post-marketing surveillance to be “a critical part of the FDA’s responsibilities,” but nobody has fixed the VAERS website in at least a month.
Moreover, I searched the Internet for news stories, blogs, or tweets about the outage. Nothing. Has nobody even noticed? The website address is printed on every Vaccine Information Statement (VIS), typically a two-page document that must, by law, be distributed to individuals with every dose of vaccine administered in the US. The CDC tells physicians to “Do your part for vaccine safety - Report to VAERS.” But the address given does not connect.
Impact on data quality
Has the website misconfiguration affected the data? It turns out that the VAERS website is accessible at vaers.hhs.gov—that is, by removing the “www.” from the address. And while VISs point to www.vaers.hhs.gov, many links on the Internet point to vaers.hhs.gov (without the www.). Therefore, the effect on the collection of data into VAERS is uncertain. Only a formal analysis can shed light on this important question. Will the CDC/FDA do such an analysis?
CDCWhat can we do
That this is happening with the vaccines’, rather than drugs’, postmarketing surveillance system is particularly unfortunate. The climate for discussions about vaccines is already hostile, and a website address that does not function properly only adds fuel to the fire. At the same time of the outage, the National Foundation for Infectious Diseases (NFID) told more than 750,000 people in a large social media campaign to promote vaccination that “vaccines are safe.” One of the graphics developed for the campaign depicts VAERS as a pillar assuring vaccine safety. Today, this pillar appears to be hollow.
Whether you are pro-all-vaccines, anti-all-vaccines, or one of the many who are neither, we all benefit from robust pharmacovigilance. But the VAERS website outage—and lack of attention it has received—demonstrates there is nothing vigilant about our current system of pharmacovigilance. And it’s time that changes.
I urge anybody who cares about post-marketing surveillance, who agrees with the FDA that it is an “essential” system, to demand that authorities immediately fix the problem, and provide the public with an explanation.
And if you by chance do not feel post-marketing surveillance is important, consider this: US President Donald Trump and the newly appointed FDA commissioner would like to accelerate FDA approvals, which means drugs may soon start entering the market with even more uncertainty over their effects.

This is total hogwash. The fact that "The Scientist" is publishing such blathering drivel is a sign of mental deficiency on the part of the editors. No fact check!
There is no problem with VAERS. There never was a problem with VAERS. If you use Google, you will find the correct web site for VAERS.
The only thing that has happened is that Peter Doshi, a well known antivaccine troll and an anthropologist without a clue about vaccines or immunology has stumbled across a way to try to access VAERS that won't work. A few minutes of simply looking at the explanation for the error will tell you what is wrong. In the example here, the correct access is www.example.com. In our case, the correct web site drops the www. Duh.
This error is telling you that the identification sent to you by the site is actually for another site. While anything you send would be safe from eavesdroppers, the recipient may not be who you think it is.
A common situation is when the certificate is actually for a different part of the same site. For example, you may have visited https://example.com, but the certificate is for https://www.example.com. In this case, if you access https://www.example.com directly, you should not receive the warning.

I question the usefulness of wiki tools like VAERS for data collection. The problem is that there is absolutely no reference control. No matter how many people report they got sick after getting vaccinated, the information is uninterpretable.
I suppose VAERS might serve a placebo function, sort of like an office suggestion box that the boss empties in the wastebasket every Monday morning.

In Decmber 2015, investigative journalsit Sharyl Attkisson reported that in March the CDC removed the latest vaccine injury court statitstics. "It was an abrupt departure from the normal practice of updating the figures monthly. Wiping the latest data means the "adjudication categories by alleged vaccine" chart on a government website no longer reflects the recent, sharp rise in court victories for plaintiffs who claimed their children were seriously injured or killed by one or more vaccine."
What the takeaway message seems to be is that the government modus operandi is to suppress information when the evidence goes against government policy.
