To jab or not to jab: confusion reigns over HPV

On September 24, Quebec joined the march of other Canadian provinces to provide free HPV vaccinations to schoolgirls. Almost immediately, women's health activists there due to safety concerns. Health Minister Philippe Couillard the voluntary program is safe. "We are not doing this just because there is a company with the vaccine on the market (or) ... because other provinces are doing it. We're doing it because it is in the interest of public health," he said.

Quebec's HPV drama echoes what's been happening across the country and around the world. A group of Canadian public health researchers published a commentary in the CMAJ voicing their concerns that we don't know enough about safety and efficacy of the jab in kids to rush through the vast immunization program we're seeing.

One of the authors, Dr Abby Lippman, : “I couldn’t understand why there was suddenly such a rush to do this when cervical cancer only kills about 400 people a year in Canada, and most of them are dying because of lack of treatment. I couldn’t see anything like the sort of evidence one would expect to support a decision like this.”

MDs on the frontlines have expressed concerned that, in light of the confusion, we should wait for more data (read Waterloo family doctor Dr Neil Arya's editorial on the subject ). On the other hand, an of physicians revealed that two thirds of Canadian MDs think we shouldn't wait if we can prevent cervical cancer.

Meanwhile, presented at the Interscience Conference on Antimicrobial Agents and Chemotherapy in Chicago showed that Gardasil appears to partially protect against 10 more HPV strains than was previously thought. These strains are responsible for 20% of cervical cancer lesions. The vaccine is currently indicated for strains 6, 11, 16 and 18.

One simply doesn't know what to think.

  1. The thing is it has never been proven that this vaccine prevents cervical cancer - it is a HUGE assumption which does not equate to good science. Dr. Diane Harper who oversaw Phase III clinical trials stated in recent interview that women who have had the vaccine are showing up in her office with irregular PAP smears and disappointed. This is being rushed and far too many assumptions made. What we do know is that far more females are being injured by the vaccine than have been saved from cervical cancer. When Health Minister Philippe Couillard says they are not doing this because there is a company on the market with a vaccine- that is EXACTLY why they are doing it and without conducting any independent safety or efficacy studies merely relying on the company that has billions invested for their data. It is unfortunate.
