When should I get the influenza vaccine?

The worst flu season ever. And it started early.

The worst flu season ever. And it peaked early.

I was asked this question by one of my infection control practitioners. We started offering the flu vaccine the first week of October and some have delayed getting the shot for fear that immunity will not last the season. She pointed me to this NPR article, “Yes, It Is Possible To Get Your Flu Shot Too Soon,” as driving the fear of too little too soon.

So when should you get the flu shot?

Short answer – I don’t know.

There are multiple variables that make it a difficult question to answer. When does flu season start? When does it end? Influenza has immunologic variation from year to year and different strains circulate each year. How good is the match between the circulating strains of influenza and the vaccine? How good is the immunologic response of the host?

So many questions. By answering these question maybe we can come up with an estimated optimal time to receive the flu vaccine. (more…)

Infectious Diseases and Cancer


Dr. William Coley. Not a brain surgeon.

With apologies to my colleagues, but infectious diseases really is the most interesting specialty in medicine. There are innumerable interesting associations and interactions of infectious diseases in medicine, history, art, science, and, well, life, the universe and everything. ID is so 42.

A recent email led me to wander the numerous interactions between infections and cancer.

There are the cancers that are caused by infection. HPV and cervical and throat cancer. EBV and lymphoma. HHV8 and Kaposi’s Sarcoma. I certainly hope I am not reincarnated as a Tasmanian Devil. (more…)

No Compromise on Vaccine Refusal


A few years ago some colleagues and I at the Institute for Science in Medicine were debating what our official position should be regarding non-medical vaccine exemptions. We all agreed that the ideal situation would be no non-medical exemptions. There is no legitimate reason for such exemptions and the evidence clearly shows that states who allow non-medical vaccine exemptions have lower vaccination rates.

The debate was about whether or not that should be our only position, to take a strong and uncompromising stance, or should we also advocate that states who do allow non-medical exemptions to make them as difficult as possible (which also is effective in reducing vaccine refusal). The concern was that the perfect solution was politically too difficult and the lesser solution was at least something (like a prosecutor including lesser charges in case they lose on the big charge).

I advocated for the latter position, which is what we ultimately decided. After the Disneyworld measles outbreak, however, I think the political calculus has changed. It is much more politically viable to simply advocate for the elimination of all non-medical exemptions. (more…)

If You Think Doctors Don’t Do Prevention, Think Again

Prevention has long been a priority of conventional medicine

Prevention has long been a priority of conventional medicine

One of the common criticisms we hear from alternative and integrative medicine proponents is that doctors don’t do anything to prevent illnesses and have no interest in prevention. They claim that doctors are only trained to hand out pills to treat existing illnesses. Sometimes they even accuse them of deliberately covering up cures and wanting to perpetuate illnesses like cancer so they can make more money by treating patients. Nothing could be more absurd. Every reputable doctor would rather prevent illnesses than treat them. In his book Heart 411, cardiologist Steven Nissen even said he would be glad to see his specialty become obsolete: “Don’t worry about us; we will gladly hang up our scalpel and stethoscope if we can find a better way to lead you to a heart-healthy life.”

Doctors own prevention. They invented it, from vaccines to clean water to preventive screening tests. Mainstream medicine was responsible for the greatest preventive achievement in history: the smallpox vaccine campaign succeeded in preventing anyone from ever getting smallpox again. I defy you to comb through historical records and find any doctor who ever said “Let’s stop vaccinating for smallpox so we can make more money treating its victims.”

Prevention is one of the six fundamental principles of naturopathy. Alternative practitioners pride themselves on prevention, but they don’t actually do a very good job of it. In fact, there is evidence that their patients are less likely to get immunizations and some of the standard preventive screening tests recommended by the USPSTF. Instead of rigorously implementing evidence-based preventive strategies, they tend to offer other speculative, untested recommendations.

Dealing with vaccine hesitancy and refusal

How do we deal with parents who would rather their babies face diseases than vaccines?

How do we deal with parents who would rather their babies face diseases than vaccines?

As long as there have been vaccinations, there has been an antivaccine movement, and as long as there has been an antivaccine movement, there have been parents who refuse to vaccinate. In a past that encompasses the childhood of my parents, polio was paralyzing and killing children in large numbers in yearly epidemics, the fear of which led to the closure of public pools every summer. In such an environment, the new polio vaccine introduced by Jonas Salk in the mid-1950s wasn’t a hard sell. In fact, satisfying the initial demand for it was the problem, not parents refusing to vaccinate their children. Since then, more and more vaccines have been developed to protect more and more children from more and more diseases, to the point where the incidences of most vaccine-preventable diseases is so low that, unlike 60 years ago, most parents today have never seen a case or even known other parents whose child suffered from a case. Even as recently as the 1980s, Haemophilus influenza type B was a dread disease that could cause meningitis, pneumonia, sepsis, and death. Since the introduction of the the Hib vaccine a mere quarter century ago, Hib has been virtually eliminated. Most pediatricians in residency now have never seen a case.

As much of a cliché as it is to say so, unfortunately vaccination has been a victim of its own success, at least in developed countries. Parents no longer fear the diseases childhood vaccines protect against, which makes it easy for antivaccine activists to provide what I like to call “misinformed consent,” by spreading misinformation that vastly exaggerates the risk of vaccines compared to the benefit of vaccinating. Parents who believe the misinformation conclude, based on a warped view of the risk-benefit ratio of vaccines, that not vaccinating is safer. Add to the mix fear mongering against the MMR based on Andrew Wakefield and his dubious 1998 case series that popularized the then-recent idea that vaccines cause autism, and it’s no wonder that parents decide that not vaccinating is safer than vaccinating. If you believe the misinformation, it’s not an entirely unreasonable conclusion. Then add to that the easy availability of “personal belief exemptions” to school vaccine mandates in many states, which include anything from religious exemptions to parents just signing a form that says they are “personally opposed” to vaccination, and it isn’t a huge surprise that vaccine uptake has fallen in some areas to the point where outbreaks can occur. It was happening in California and my own state of Michigan. (more…)

Reviewing Andrew Wakefield’s VAXXED: Antivaccine propaganda at its most pernicious


I’ve finally seen it. I’ve finally seen Andrew Wakefield and Del Bigtree’s “documentary” VAXXED: From Cover-up to Catastrophe, and I didn’t even have to pay to see it! Now, having watched Wakefield and Bigtree’s “masterpiece,” I can quite confidently say that it’s every bit as accurate and balanced a picture of vaccine benefits and risks as Eric Merola’s two movies about the quack Stanislaw Burzynski and his Second Opinion: Laetrile at Sloan-Kettering are about cancer and cancer research, The Beautiful Truth is about the Gerson protocol for cancer, Simply Raw: Reversing Diabetes in 30 Days is about diet and diabetes, Expelled! No Intelligence Allowed is about evolution, and The Greater Good is about…vaccines! Of course, based on what I knew of the story, saw of the VAXXED trailer (which deceptively edited together statements by William Thompson), and have discussed about the efforts of Andrew Wakefield, Del Bigtree, and Polly Tommey to use VAXXED as a tool in a publicity campaign to try to spread fear, uncertainty, and doubt (FUD) about vaccines using the “CDC whistleblowerconspiracy theory (about which a primer can be found here), I shouldn’t have been surprised, but I was actually surprised (slightly) at the manipulative depths to which this film sinks.

On the plus side, its production values are better than those Eric Merola’s films (although I, with no experience, could probably make a film with better production values than Merola), but that just makes it somewhat more effective propaganda. In my review and discussion of the movie and its claims, I will discuss the claims made by Bigtree and Wakefield as well as the movie as a movie. Unfortunately, there is so much misinformation in this 91 minute documentary that I will only be able to hit the “high” points without going far, far beyond even a Gorski level of logorrhea in this post. Worse, there is a considerable amount of dishonest framing, in which actual facts and events are presented in a deceptive manner to tell a distorted narrative. Before that, though, let’s meet the key players.

How low antivaccine “warriors” will go: Of Facebook harassment reporting algorithm abuse and publicly attacking a 12 year old boy

NOTE: Anyone who has seen several derogatory articles about me on the web and is curious about what the real story is, please read this and this.
Marco Arturo

I was going to write about something else this week, but events over the last several days led me to change my mind. The first was the reaction of a pseudonymous antivaccine “warrior” going by the ‘nym Levi Quackenboss to a viral video posted by a 12-year-old boy named Marco Arturo. The second was my learning that other antivaccine “warriors” had resumed abusing the Facebook reporting algorithm to get pro-science advocates supporting vaccines banned from Facebook for periods up to 30 days and thereby silence them. I wrote about this latter tactic a couple of years ago, when the Australian antivaccine group the Australian Vaccination Network (AVN), or AVN (which was forced to rename itself the Australian Vaccination Skeptics Network in 2014), started abusing Facebook’s algorithm for reporting harassment and abuse in order to get members of the skeptic group Stop the Australian Vaccination Network (SAVN) temporary Facebook bans. It’s a tactic that has continued, with a fresh batch of temporary bans issued by Facebook in response to bogus complaints over the last few days.

I’ve frequently written about how often the preferred tactic of antivaccinationists and others pushing medical pseudoscience is not to answer criticism with evidence, science, and rational argument, but rather to respond with attacks and attempts to intimidate and silence. The reason, of course, is that they do not have any of that to support their beliefs. At some level, I suspect that many of them know it. Be that as it may, those of us who lament how few physicians and scientists, even those sympathetic to scientific skepticism, are willing to publicly speak out and call the quacks to task know that the consequences of doing so are often quite unpleasant: Online attacks, poisoning of one’s Google reputation, attempts to get one banned from Facebook, and, of course, the antivaccinationists’ favorite: Harassment through one’s job by complaining to one’s bosses. To illustrate these hazards, I’ll start with the story of Marco Arturo, before moving on to a more organized effort. (If you read my not-so-super-secret other blog, you’ll have heard of Marco’s story before, but I’ll summarize here as well.) Then I’ll update you on how Facebook continues to allow its reporting algorithms to be abused to silence pro-vaccine voices there. I’ll finish up with examples of what we at SBM have experienced and some thoughts on what can be done. (more…)

Does your antivax doctor have another agenda?

A witch placing a scorpion into a potSeveral weeks back, I wrote a piece in praise of Michigan’s Fresh Air Camp’s decision to admit only properly vaccinated children. Predictably, there was a bit of a backlash from people who, despite the obvious benefits, oppose vaccinations.

I can’t fault a parent for the decisions they make for their kids. We all work from the gut when it comes to our children, and this can make us see risks incorrectly. But I cannot forgive people who should know better. Medical professionals should all support basic public health such as vaccination, just as they should support healthy eating, physical activity, and clean water. I feel strongly enough about this that I have called for pulling the licenses of doctors who oppose vaccination.

As usual when I write about vaccines, I got plenty of hate mail and disturbing blog comments – no biggie. That’s part of standing up for the truth. What really disturbed me was a local doctor, here in the same community that the camps serve, coming out publicly against the new policy. When a medical professional weighs in on a matter of public health, people listen. (more…)

Medical exemptions to vaccine mandates for sale after SB277! Get ’em before they’re gone!

NOTE: Anyone who has seen several derogatory articles about me on the web and is curious about what the real story is, please read this and this.

SB277, which eliminates nonmedical exemptions to school vaccine mandates in California, is a very good law, but it's not perfect. Unfortunately, one provision allows the issuance of medical exemptions based on the say-so of doctors using antivaccine misinformation and pseudoscience.

SB277, which eliminates nonmedical exemptions to school vaccine mandates in California, is a very good law, but it’s not perfect. Unfortunately, one provision allows the issuance of medical exemptions based on the say-so of doctors using antivaccine misinformation and pseudoscience.

I realize that it’s a cliché to say so, but some clichés are true. Time really does fly. It’s hard to believe that a year ago California—and, by proxy, the rest of the country—was in the throes of a major political war over the bill SB277. SB277, you will recall, was a bill introduced into the California Assembly in the wake of the Disneyland Measles outbreak in early 2015 that eliminated non-medical exemptions to school vaccine mandates beginning with the 2016-2017 school year. Ultimately, SB277 passed and was signed into law by Governor Jerry Brown last July. It was an uncommon victory for science and public health, and already appears to be having a positive effect on vaccine uptake in kindergarten children.

Unfortunately but not unexpectedly, to say that the proposal and passage of SB277 into law drove the antivaccine movement into even greater fits of crazy in response is to put it mildly. It became a common trope on antivaccine websites and blogs to see SB277 compared to fascism, in particular the Holocaust. Robert F. Kennedy, Jr. and “Dr. Bob” Sears explicitly compared SB277 to the Holocaust. Truly, the Godwin was strong in the antivaccine movement. One particularly offensive meme that went around at the time consisted of antivaccinationists suggesting that SB277 was a major step in the direction of requiring unvaccinated children to wear a badge or armband to identify themselves, the way that the Nazis required Jews to wear badges or armbands with a yellow Star of David on them. One, Heather Barajas, even went so far as to be photographed with her children wearing such an “unvaccinated” badge and juxtapose that photo with photos of Jews from the Third Reich wearing yellow Stars of David.

Vaxxed and the Tribeca Film Festival: How Robert De Niro learned the hard way about Andrew Wakefield and the antivaccine movement

Robert De Niro made a massive mistake last week.

Robert De Niro made a massive mistake last week. Fortunately, he started to make up for it.

One of the disadvantages of only doing one blog post a week here at Science-Based Medicine is that sometimes stuff happens at too fast a pace for me. If something happens on Tuesday, by the time Sunday rolls around and it’s time for me to do my weekly post, it’s often old news, too old to bother with. That’s why it’s a good thing that I have my not-so-super-secret other blog, where I can keep up with such events. On the other hand, the advantage of a once-a-week posting schedule is that there are times I can look back at a story that evolved over the last week and, instead of blogging about it in daily chunks, I can put together a post that tells the whole story and puts it in context. Something like that happened last week. The beauty of it is that I played a major role in bringing the story to public consciousness, followed the story as it evolved, and now can provide a fairly complete recounting. Or so I hope.

First, however, let’s take advantage of another good thing about waiting to blog about a story, namely getting to see the reactions of quacks to what happened. No one can do it better than everybody’s favorite all around quack, crank, and all-purpose conspiracy theorist Mike Adams, who greeted me yesterday morning with this headline: VAXXED film pulled from Robert De Niro’s Tribeca Film Festival following totalitarian censorship demands from pharma-linked vaccine pushers and media science trolls. What on earth is Adams talking about, you might wonder? In case you haven’t been following the news, here’s a link to the New York Times story on the same incident: “Robert De Niro Pulls Anti-Vaccine Documentary From Tribeca Film Festival.” Basically, the 2016 Tribeca Film Festival selected an antivaccine documentary directed by Andrew Wakefield for screening and then thought better of it after a major uproar and a whole boatload of bad press.

I’ll deal with Adams’ post a bit later because it’s so hilariously nutty but also because it is basically the propaganda line that antivaccinationists are putting on this PR debacle brought about by Andrew Wakefield and Robert De Niro. (I never thought I’d use those two names in the same sentence.) Let’s go back a week and see what I mean. (more…)
