‫Can you guess how an egg could save your life?
‫A vaccine is a very simple means to train the body and to prevent it from being infected by a bacterium
‫or virus.
‫We are manufacturing here on this site.
‫Influenza vaccines, seasonal and pandemic influenza vaccines...
‫We get these eggs from about 14 different farms spread all over Germany and right into the Netherlands
‫as well.
‫The manufacturing process of our influenza vaccine starts with the inoculation of the influenza virus
‫into eggs, followed by an incubation at well controlled temperatures
‫under well controlled conditions. During that incubation phase.
‫the influenza virus is multiplying. In the second stage
‫now, we harvest the allantoic fluid from the eggs.
‫This allantoic fluid now contains millions and millions of copies of influenza virus. In the next stage
‫We purify the virus from the allantoic fluid and we also split the virus into small particles and inactivate it
‫chemically in order to prevent it from being able to further replicate. In the fourth stage
‫we sterile filter to yield a sterile suspension of purified influenza split virus with each of the four
‫influenza strains we receive from the WHO reference laboratories in order to formulate a quatravalent
‫vaccine containing two B strains and two different A strains as the base composition for this vaccine.
‫The manufacture of our bulk antigen takes us about 30 days, followed by another 30 days necessary for
‫the formulation, filling and packaging of the vaccine.
‫Our whole manufacturing process and the success of what we are doing depends on the people we have.
‫This year, we will produce approximately 50 million doses of influenza vaccine, delivering a very
‫safe product which is able to protect people from serious infection.
‫That great video was from the welcome trust.
‫It should make what's going on in the diagram
‫bit clearer.a
‫But don't worry, we'll do it together.
‫Step by step.
‫Bit by bit.
