Killer meningococcal disease outbreak – some context

Helen Petousis Harris • Nov 30, 2018

Is there a killer epidemic of meningococcal disease in NZ? In 2018, as of November, 10 people in NZ died of meningococcal disease and six of these deaths were caused by Group W (as opposed to A, B, C, Y, and Z). Historically most deaths in NZ have been caused by Group B so this is a change. Group W … Read More

Meningococcal rare but deadly, yes there are vaccines

Helen Petousis Harris • Nov 07, 2018

Meningococcal disease is scary, really scary. Like many of our most insidious diseases meningococcal disease often presents like a flu, and most people who present with a flu-like illness have… a flu like illness. How much meningococcal disease is in NZ? In 2014 NZ had 45 cases and in 2017 there were 112. So far … Read More

How safe is the MMR vaccine?

Helen Petousis Harris • Jul 13, 2018

In the tiny Pacific Nation of Samoa, on Friday 6 July 2018, two babies died shortly after receiving MMR vaccine. How could this happen? Lots of discussion is going around about this tragedy, and even more questions. Here are some responses to the things I have been asked this week summarised under the headings below. About MMR vaccines How … Read More

Move over ASIA now we have HANS

Helen Petousis Harris • May 12, 2018

There appears competition to claim discovery of HPV syndromes. Another in a list of attempts at assassinating the safety of HPV vaccine has been retracted this week. This time from Nature Scientific Reports. Grant Jacobs has provided a commentary on another just a day earlier. That one is a real doozer, an author with a fake name … Read More

The brouhaha around placebo choice in vaccine trials

Helen Petousis Harris • Feb 21, 2018

There exists a sustained brouhaha around the nature of the placebos used in the clinical trials for Gardasil. The notion that some of the most rigorous vaccine trials ever conducted are questionable on account of their well thought out placebos is ill conceived at best. This is after over 270 million doses and huge epidemiological studies from all over the … Read More

Proving HPV vaccines really prevent cancer

Helen Petousis Harris • Feb 19, 2018

In the clinical trials for HPV vaccines cervical cancer was not a primary endpoint. An endpoint in a clinical trial is a disease or a symptom of interest. I want to explain why cancer was not an endpoint these efficacy studies. Instead surrogate endpoints were used. Why not, given that is what the investigators wanted to prevent? Because you can’t … Read More

Media, Dr Google, and the adverse events you were looking for

Helen Petousis Harris • Nov 13, 2017

The perception of risk is greatly influenced by the media and related to the relationship between hazard and outrage, or Risk = Hazard + Outrage (Sanderman). Basically, the risks that can kill you are often not the risks that get you all alarmed. I am a bit scared of things with at least six legs but genes dictate it … Read More

Who is Levi Quackenboss and what is she saying about vaccine debates?

Helen Petousis Harris • Nov 02, 2017

Quackenboss is a vaccine denier with a history of internet bullying and going loopy when someone says something positive about vaccines. She hides nameless and faceless behind a blog, or captured in a state of self-glorification during an interview with HealthNut News. I know not her name, qualifications, or profession because they do not appear to be provided but she has plenty … Read More

Aluminium adjuvants, immune dysfunction, and the AV syndrome scammers

Helen Petousis Harris • Sep 15, 2017

Vaccine scammers I call them. They prey on people with a sick kid. Perhaps they want to flog dietary supplements or bleach enemas but today I refer to the proponents of a variety of fake syndromes, which they claim have been induced by vaccines and/or vaccine adjuvants*. The most infamous vaccine scammer in this case is Andrew Wakefield, but this … Read More

Mumps outbreak – add fire and watch it burn

Helen Petousis Harris • Sep 06, 2017

The inevitable mumps outbreak is upon us. Inescapable because we have a significant proportion of the community who are not immune, dry tinder to a flame. NZ has high immunisation coverage right? So why has this happened? Here is the story. Back in the early 1990’s NZ had a terrible measles epidemic and seven people died. Waking up … Read More
