Glaxo Smith Kline have recalled a batch of Swine Flu vaccines containing around 170,000 vaccines in Canada, due to a larger than expected number of adverse reactions. GSK say that they expect to have reports of a severe adverse reaction in a approx 1 in every 100,000 persons receiving the vaccine, however, with this particular batch they were seeing about 1 in every 20,000 after six people suffered anaphylaxis shock after having the vaccine.

CTV National News: John Vennavally-Rao reports that more than 100,000 doses of the H1N1 vaccine were withdrawn on Thursday after a number of people who received the vaccine suffered a potentially life threatening allergic reaction which has raised some concerns. Glaxo Smith Kline say however, that this is just a precautionary measure.

Rice Researchers Seek Better Vaccine Procedure to Target Flu Viruses

As manufacturers work furiously to make a vaccine to protect against 2009 influenza A (H1N1) virus, a Rice University bioengineer is trying to improve the process for future flu seasons. The goal is to shorten the time it takes to identify targeted flu strains and manufacture the vaccines for them.

Although we are waiting eagerly for the first swine flu vaccine to hit the market, it seems production of the vaccine will be much less than the original estimates. According to a warning from the World Health Organization (WHO), supply will be much less than anticipated earlier, especially with the winter season approaching in the northern hemisphere. Per initial estimates from October onwards, about 94 million doses of vaccine could have been manufactured by the pharmaceutical companies, but this target has already been slashed by 50-75% due to poorer than expected yield from the virus strains.

…The vaccine market has emerged as one of the most lucrative segments for pharmaceutical companies. It is expected to grow at a CAGR of over 13% during 2009-2012. The swine flu pandemic should fuel further growth in this segment.

Epidemiologists Can't Determine Why Some People are killed by H1N1

Around the world, vaccine manufactures are rushing new swine flu vaccines into clinic trials and booking pre-orders from worried Public Health officials, while epidemiologists are still puzzling out how the new flu works and why many young people without any health complications are often hit the hardest by H1N1.

Quel Surprise! Swine Flu Is Ready

The World Health Organization last week raised the pandemic level to phase 6, calling for the implementation of “individual, societal, and pharmaceutical measures” as well as implementation of contingency plans for health systems. WHO continues to recommend no restrictions on travel and no border closures, however. Some 100,000 doses of Protein Sciences’ PanBlok vaccine, being produced from this week forward, will be targeted for clinical trials and for vaccinations in countries that have granted regulatory clearance. Meanwhile, following the WHO announcement, GlaxoSmithKline says it is going to increase production of its anti-viral Relenza, and continue developing a swine flu vaccine. Separately, Chinese vaccine maker Sinovac Biotech says it hopes to put its H1N1 vaccine through its first clinical trial by the end of July.
