Mandatory flu vaccinations for health care workers

Nosocomial infections, or hospital acquired infections, are a significant issue in hospital environments and has become a serious public health issue. These infections include everything from drug resistant bacteria to several viruses, including the flu.  They have serious repercussions in a hospital environment–everything from employee absenteeism to higher mortality rates of patients.  For example, influenza, which has a reputation of being innocuous, can be dangerous to infants, the elderly and immune compromised patients.  Further, a flu outbreak can leave a hospital short-staffed with sick nurses, techs and physicians, making it more difficult to deal with the outbreak itself.Read More »Mandatory flu vaccinations for health care workers

CDC makes recommendations on the use of HPV vaccine in males

The CDC’s Advisory Committee on Immunization Practices (ACIP) recommends routine vaccination of males aged 11 or 12 years with HPV4 administered as a 3-dose series (recommendation category: A, evidence type: 2§). The vaccination series can be started beginning at age 9 years. Vaccination with HPV4 is recommended for males aged 13 through 21 years who have not been vaccinated previously or who have not completed the 3-dose series. Males aged 22 through 26 years may be vaccinated.Read More »CDC makes recommendations on the use of HPV vaccine in males

Worldwide progress in measles control–vaccines get credit

The Centers for Disease Control and Prevention, commonly known as the CDC, this week published Progress in Global Measles Control, 2001-2010.  In 1980, there were over 2.6 million deaths worldwide from the measles virus.  Though measles is considered by many people as innocuous, it is, in fact, a relatively dangerous infection with a variable prognosis.  For vast majority of sufferers, there are few complications, but for some, even healthy individuals, it can be debilitating or even fatal.  Notwithstanding, I have always wondered why the anti-vaccination gang is willing to risk the possible death of their children by refusing to inoculate them, in light of very few risks or side effects of the vaccination itself.  I digress.

Logical fallacies Part 1-Anti-vaccination gang’s naturalistic fallacy

In this blog, the term “logical fallacy” is used frequently to illustrate a logical or rational failure of a particular argument. There are several definitions of what constitutes a logical fallacy:

[pullquote]❝A logical fallacy is, roughly speaking, an error of reasoning. When someone adopts a position, or tries to persuade someone else to adopt a position, based on a bad piece of reasoning, they commit a fallacy.❞–Logical Fallacies[/pullquote]

[pullquote]❝An argument that sometimes fools human reasoning, but is not logically valid.❞–Fallacious Argument[/pullquote]

[pullquote]❝In logic and rhetoric, a fallacy is usually an improper argumentation in reasoning resulting in a misconception or presumption. By accident or design, fallacies may exploit emotional triggers in the listener or interlocutor (appeal to emotion), or take advantage of social relationships between people (e.g. argument from authority). Fallacious arguments are often structured using rhetorical patterns that obscure any logical argument.❞–Wikipedia[/pullquote]Read More »Logical fallacies Part 1-Anti-vaccination gang’s naturalistic fallacy

FDA approves Zostavax vaccine to prevent shingles in individuals 50 to 59 years of age

One of the consequences of contracting chicken pox (Varicella zoster) is that the virus is not destroyed by the body’s immune system.  Once the symptoms of chicken pox disappear, the virus hides itself in the basal root ganglion, unseen by the immune system.  Even though the body generated an immune response to the original zoster infection, after several decades, the response is either weakened or disappears.

Eventually, due to unknown factors (such as stress or other illnesses), the zoster virus “moves” along the nerve bundles, and causes a second infection with much more serious consequences to the patient.  This second infection is called herpes zoster (despite being the same exact virus, it was given a different name probably because it was originally thought to be two different viruses, but in this case, it’s not given a formal biological binomial name), or more commonly, shingles.  This infection usually happens when the patient is in their 50’s and older, though it can happen at any time.Read More »FDA approves Zostavax vaccine to prevent shingles in individuals 50 to 59 years of age

Joe Mercola: Proof positive that quackery sells

Orac, in his blog post, Joe Mercola: Proof positive that quackery sells : Respectful Insolence, hits the nail on the head about Mercola, one of the biggest quacks on the internet.  I don’t know if Mercola actually believes in his particular brand of science-denialism, but he uses it for one reason:  to have people with legitimate medical concerns send their money to him.  In case you don’t click on the outlink above, here are some precious quotes from Orac.

[pullquote]Putting the word “visionary” in the same title with the word “Dr. Mercola” is profoundly offensive to anyone who values reason, science, and science-based medicine.[/pullquote]Read More »Joe Mercola: Proof positive that quackery sells
