Per Wikipedia:  “Haemophilus influenzae (formerly called Pfeiffer’s bacillus or Bacillus influenzae) is a Gram-negative, coccobacillary, facultatively anaerobic pathogenic bacterium belonging to the Pasteurellaceae family. H. influenzae was first described in 1892 by Richard Pfeiffer during an influenza pandemic.

“The bacterium was mistakenly considered to be the cause of influenza until 1933, when the viral cause of influenza became apparent, and is still colloquially known as bacterial influenza. H. influenzae is responsible for a wide range of localized and invasive infections. This species was the first free-living organism to have its entire genome sequenced.

“In 1930, two major categories of H. influenzae were defined: the unencapsulated strains and the encapsulated strains. Encapsulated strains were classified on the basis of their distinct capsular antigens. The six generally recognized types of encapsulated H. influenzae are: a, b, c, d, e, and f. Genetic diversity among unencapsulated strains is greater than within the encapsulated group. Unencapsulated strains are termed nontypable (NTHi) because they lack capsular serotypes; however, they can be classified by multilocus sequence typing. The pathogenesis of H. influenzae infections is not completely understood, although the presence of the capsule in encapsulated type b (Hib), a serotype causing conditions such as epiglottitis, is known to be a major factor in virulence. Their capsule allows them to resist phagocytosis and complement-mediated lysis in the nonimmune host. The unencapsulated strains are almost always less invasive; they can, however, produce an inflammatory response in humans, which can lead to many symptoms. Vaccination with Hib conjugate vaccine is effective in preventing Hib infection, but does not prevent infection with NTHi strains.”

Vaccine Statistics

When debating informed consent, it is important that people calculate the risk versus the reward for all options.  Here are some facts, according to VAERS and the CDC.

  • Since 2000, there is an average of fewer than 7 deaths from HiB-related meningitis in the US annually.
  • Since 2000, there have been at least 841 deaths reported to VAERS associated with the HiB vaccine.
  • Since 2000, there have been 31,789 adverse events reported to VAERS.

 These numbers are unambiguous:  children have at least a six-fold greater chance of dying from the HiB vaccine than from HiB.  If the FDA’s assessment of reporting compliance is correct (<1%), even this elevated risk could be underreported by two orders of magnitude.  The death rate from HiB-related infections is so low that the CDC doesn’t even attempt to list the numbers on their websites for parents or providers, but reports of deaths from the HiB vaccine are publicly available for anyone with an internet connection.  Other statistics from VAERS dating back to 2000:

  • 951 immediately life threatening complications
  • 525 permanent disabilities
  • 4178 hospitalizations or extensions of hospitalization
  • 12,366 emergency room or office visits related to complications

The following section will reference the Hiberix product insert as provided by the FDA.  It should be noted that the HiB vaccine contains high levels of aluminum adjuvants.

Contraindications (do not administer):

  • Allergy or sensitivity to any component of the HiB vaccine.

Adverse Events (as reported by the manufacturer):

  • Guillain-Barré syndrome, syncope, apnea, injection site pain/redness/induration, irritability, drowsiness, fever, anorexia, fussiness, fever, restlessness, diarrhea, vomiting, anaphylaxis, convulsions, angioedema, hypotonic-hyporesponsive episode, vasovagal response, rash, urticaria

Editor’s Opinion

Expansive discussion of this vaccine is unnecessary as the risks from the vaccine clearly and markedly outweigh the near-negligible risks from the disease it’s purported to protect against.  We do not recommend that anyone be administered the HiB vaccine.
