Health Watch

I was thinking only the other day that my blog sorely lacked anything even vaguely health-related. The thought makes me want to curl up in shame as a future medical doctor and public health worker.

Introducing: this blog post, which features one of the loudest health stories to break this year. Other stories I hope to watch in the future are the sin tax reform and the rising mental health awareness.

Read this blog post to find:

  • Outstanding details about a key health issue of the past year
  • My amateur commentary and stance on the issue

Dengvaxia: A Study on Politics in Health

Looking at the facts of the ongoing case, it’s not hard to assume money unethically and even illegally passed hands somewhere at the top. The controversy also made one thing astoundingly clear: our national health system is cracked and prone to fail.

Timeline and Key Points

By late 2016, critics from the legislative and private societies escalate in hounding the DOH on their decision to implement a 3.5 BILLION-PESO mass immunization program with a new vaccine previously untested in the general market. By 2017, the issue has escalaed to outraged panic and a widespread distrust of the government and, unfortunately, of vaccines.

The dealings were fishy. The vaccine rolled out in the mere span of months, edging out other priorities in the national health agenda. Instead of being made available to the market for private, voluntary consumption, the vaccine was administered through a program to more than 830000 children in schools and through private officials.

A percentage is now possibly at risk of more severe dengue. All of them are endangered by bad public policy and mass hysteria.

  • 2015 May: In a story that broke out late 2017, the Department of Foreign Affairs reports that then-Health Secretary Garin met with toonofficials from French pharmaceutical Sanofi Pasteur, the developers of Dengvaxia. The dinner meeting involved a company VP, senior director and country manager. Garin initially denies under scrutiny any meeting (“I only met with the Health Minister”), but later admits and says the meeting had no malice.
  • 2015 December: Then-President Aquino meets with officials from Sanofi Pasteur at an international summit. This is branded as the first official meeting and conceptualization of the government acquisition of Dengvaxia.
  • 2015 December: Weeks after that first official meeting, Dengvaxia is licensed and approved for use in the Philippines by the Food and Drug Administration. The vaccine has been previously approved for use in endemic areas in Mexico. Prior to approval, data presented say subjects from Metro Manila and Cebu participated in the phase 1 to 3 of the clinical trials. A decade of “efficacy and safety studies” in 10 countries, involving 30000 children, has been conducted.
  • 2016 January: The Philippines Formulary Executive Council debates on procurement. The proposed funding to include Dengvaxia into the government program involves drawing from the savings of other agencies. The FEC does not recommend its introduction to a mass immunization program, and concedes as an exemption to small-scale application (1 year, considering LGU capacity; P50 million). Undersecretary Hartigan-Go says that the inclusion of Dengvaxia is made by a political decision by a higher committee. Note that Hartigan-Go is also affiliated with Zuellig Pharma, the distributor of Dengvaxia.
  • 2016 April: The World Health Organization releases a document on their recommendations. They present the following considerations for governments contemplating the introduction of the vaccine: (1) for areas wih a high proprotion of already exposed individuals (at least 50%), (2) to those aged 9 years old and above, and (3) administer in three doses. Later December 5 2017, WHO will clarify that they never recommended the introduction of the vaccine in a national immunization program, versus implications made by the DOH.
  • 2016 April: The Department of Health rolls out a 3.5 billion-peso mass immunization program. The program provides free vaccines to selected Grade 4 public school students, covering Metro Manila, central Luzon, and CALABARZON. A Special Allotment Release Order for budget is made to accommodate the expense, which almost equates to the entire vaccination program of the DOH in the last year. The budget is also coursed through  the Philippine Children Medical Center. Therchase order is made without approval from the Philippines National Drug Formulary. An initial 730000 children received the first of three doses.
  • 2016 March to August: The DOH later reports that in this period, 997 “adverse effects following immunization” occurred, as cited in a draft report by the House of Representatives Committee on Health (see later). Of these, 30 cases were serious and required hospitalization. The DOH reports 2 deaths, while the house committee receives counterfactual reports citing at least 4 fatalities. No other details on “adverse effects” and updates were provided.
  • 2016 October: The House with house representative Tan probes the issue. Senator Gordon seeks an investigation on the “undue haste” in using the program.
  • 2016 October: On the same month, the media also covers the death of C de Gyzman, a 10 year-old child diagnosed with dengue (DHF/shock). Doctor Antonio Dans of the Philippines College of Physicians: “all dengue breakthroughs after vaccination are vaccine-induced”.
  • 2016 December: The FDA orders Sanofi to stop advertisements saying Dengvaxia is an over-the-counter drug.
  • 2017 May: FDA orders Sanofi and the chain Watson’s to stop promoting and offering immunization services without authorization. On October, both parties pay the penalty of five thousand pesos for failure to comply with said order.
  • 2017 May: The program is temporarily stopped, but Sec. Ubial later resumes the program. The need to complete doses is the commonly cited justification.
  • 2017 November: Sanofi issues a warning against its own vaccine, based on new analysis of six years’ clinical data. Dengvaxia, administered  to a person who has never had dengue, could lead to “more cases of severe disease”.
  • 2017 December: Health Secretary Duque suspends the program, with the promise that the DOH will closely monitore the health of the vaccinated children.
  • 2017 December: The blue ribbon committee and the panels on health and demography, and finance reopen investigations. Key actors such as Aquino and Garin are put to question.
  • 2018: Unused stocks of bought Dengvaxia are set to expire.
  • 2018: The European Medicines Agency will decide on the marketing of Dengvaxia in EU States and Iceland, Liechtenstein and Norway.

The Many Flavors of Failure

I first heard about Dengvaxia as an example offhandedly mentioned in a health-related (or was it development-related?) debate round a year or two ago. Back then, I didn’t understand the many ways the proceedings were flawed or suspicious. People were proud that the Philippines was the first Asian country to roll out the vaccine. I was like, okay, cool.

Fast forward to December 2017, and the case is hot enough that it was the focus of one of our epidemiology/policy classes under the research module. The curiosities surrounding the immunization program cross over different fields, from research ethics, good governance, public health policy, and more.

Corporate Interest

Corporate innovation often penetrates the market without any public regulation. In many cases, the government can have no pre-existing framework to deal with such novelties. This is the case of Uber worldwide, making strides while policies scramble to catch up.

What makes this case so interesting and infuriating is that the Philippines does have existing frameworks with regards to the introduction of drugs to the country’s national health program. The FEC and the PNDF exist for a reason. And yet, damningly, health executives chose to ignore the recommendedation of health experts— without apt justification—- in what is probably the service of corporate interest.

Research Ethics and Validity

It’s easy to be fooled by press releases. Sanofi says that clinical trials have been conducted, implying proof of safety, concept and efficacy. What they don’t say is this (download source):

The clinical trials are still ongoing. The data they cite refer only to a primary endpoint, and not the actual end of the clinical trial. Not to mention the related lack of common sense; if the product hasn’t been tested in private markets, where did it get the support to enter public, mandatory programs?

Add their obsfucation. Up to the 2017 hearings the operational definition of “severe dengue” used by Sanofi, DOH officials, health critics and journalists still differ. Is it the improbably tame version of 2 days fever and some bleeding? Or dengue hemorrhagic fever and shock?

Futile Protocols and Power Asymmetries

As mentioned, we do have checks and balances. Within the exective, the FEC is meant to provide to expert recommendations toward public policy (and now, we recommend, the council should be independent of the executive). Yearly budget negotiations are meant to concretize the vision of the government when it comes to program prioritizations. Senate and Lower House committees exist to fish out discrepancies. And finally, the Supreme Court arbitrates for the protection of rights.

So where were all of these mechanisms? They existed, but were circumvented. The DOH launched the program undermining the FEC, creating exemptions, and drawing money from a special order. The mechanisms existed, but the Congress was too late and also toothless.

The last bastion, the media, pulls through, but gains momentum and public interest too late. We are a people accustomed to reactive measures, not proactive and protective ones.

A power asymmetry must exist for these failures to happen, and it’s concentrated heavily on the hands of people who stand to profit. Is it P-Noy, who wanted to add one last credential to his administration? Was it a top government official, who stood to profit in under-the-table dealings?

We need to strengthen these structures that are in place to properly inform policies. How can we help? Put pressure on our Representatives to care, drive more public interest in matters of health? We’re open to suggestions here…

Pharmacovigilance and Professional Practices

As the DOH promises to monitor the health of all children who took the vaccine, I can only hope for the best. This is a DOH that must evolve from it’s previous incarnation, the one which:

  • Did not document which of the children had dengue previously and which are exposure-free
  • Cannot quantitatively define what “adverse events” meant in their report
  • Lead into this storm

Fear and Surrender

In general, vaccination coverage in the country is rising. But non-compliant health decision-makers still persist, mainly due to a lack of awareness on it’s importance, failure of accessibility and even fear of the unknown.

Here, the DOH under Garin is reported to have failed in reaching its coverage goals. The percentages were way off the target (Philstar, 2014):

A paper by Castillo et al (2014) cited that majority of cases in a measles outbreak in 2010 involved non-immunized children (download source):

The failure of the Dengvaxia program to assure the safety of our citizens is one that damages the efforts of the Expanded Program on Immunization towards here immunity.

Children, bless their souls, have died. The people’s fears are rationalized: vaccination equates serious and harmful consequences. These are lessons that may take years and millions of pesos to unlearn.

Final Notes

The understanding that health is a system and is part of a system is an invaluable one. In an ideal world, healthcare exists within a system where politics is powerless. In reality, health becomes the battleground of conflicting interests. Unfortunately the only certain casualties are the people.

To be fair to many of the actors in this story, catching a crisis as it happens in front of you can be impossible. Sometimes we really can do nothing but be late and retroactive. Most officials, workers and people on the ground are probably blameless, working diligently within their capabilities. This nature absolves them of malice, but not accountability.

The intersection of fields makes it clear that the burden of quality healthcare rests on all types of professionals and influencers. It comes down not only to doctors and pharmaceutical developers, but also to policy makers, economists, media influencers, local government units, behavioral scientists, and so on. We all have a role to play, and this continuing controversy teaches us to play that role with understanding and urgency in the future.
