I found this paragraph in a document and thought I would send it along as a partial explanation of the system. Don't forget until Medicago proves it's system is safe it will have difficulty getting cooperation from government authorities. I'm long because my paragraphs set out the delay in the current system. However, this isn't the first company I've been 'interested in'. Hopefully it will be the one that pays off both for the Longs and for world health.
No decision to produce H7N9 vaccine for a U.S. national vaccination response has been made. CDC is working on developing candidate vaccine viruses (CVVs) from 2 different H7N9 isolates CVV is a flu virus that is selected and prepared for use by vaccine manufacturers to make a flu vaccine. These CVVs could be used to manufacture vaccine if one is needed. Candidate vaccine viruses are typically chosen based on their similarity to flu viruses spreading and causing illness in people as well as their ability to grow easily in chicken eggs, which is the primary method of manufacturing influenza vaccine. Without a high-yield candidate vaccine virus, it can be very difficult to manufacture vaccine to protect against a new influenza virus.
On 1 May 2013, CDC offered to begin shipping potential candidate vaccine viruses to qualified laboratories. It's important to note that influenza vaccine production is complex and can be unpredictable and has many critical and time-sensitive steps; delay at any point during these steps can result in delays in the availability of influenza vaccine. However, it usually takes about 6 months to produce large quantities of influenza vaccine.
