There are actually several issues that have all contributed to the current vaccine problems:
- As others have suggested before, the method of vaccine production (using eggs to incubate the virus) has given lower yields than in other years. (Can't really blame anyone for that; its basically biology in action.)
- The vaccine companies failed to inform the customers (i.e. the government) until it was too late that production problems might cause delays in filling the orders. (so for that, you can blame the company)
- The Canadian government decided to have the production run finished for the seasonal flu vaccine before switching over to H1N1. In a way, it saves production time overall, since they don't have to repeatedly change production lines from seasonal to H1N1 back to seasonal. However, it did mean that there was a delay in getting the first batch of H1N1 vaccine out. This is something that
might be blamed on the conservatives (although its one of these things that has no real right-or-wrong answer, since people should also be vaccinated against seasonal flu strains as well.)
- There are 2 forms of the vaccine that were produced.. one with adjuvant (an additive to make the vaccine more effective), one without. The company was providing the vaccine with adjuvant, however, there were
initially concerns that it hadn't been tested enough on pregnant women, so they stopped production to switch to the adjuvant-free version, adding to the delay. Since that time however, there have been studies showing the safety of the adjuvant-added vaccine for pregnant women. So, the conservatives could be blamed for getting the company to unnecessarily manufacture a second 'version' of the vaccine, but at the time it probably seemed like the 'safe' thing to do.
- Early polls suggested many people weren't going to get vaccinated. So, its almost understandable that the public health units weren't expecting as much response as they are currently getting. Perhaps had people made the proper decision to get vaccinated early (and indicated as such in the early polls), perhaps flu clinics would have been better organized.
So, the whole H1N1 flu vaccine mess that we're in has many causes.
