Hello, I am 37 years old and I have been having problems with flues and influenza viruses since I was a kid. My immune system is not working properly, but I keep it under control with a help of meds. Sometimes I used oseltamivir and it helps with the infections, but I have heard that there has been problem lately with the production, something about some missing step in its multiple synthesis. What’s that all about?
I think that you are referring to a situation that happened couple of years ago, in early 2005. Roche announced that they have a problem with producing amount enough for the market. They said it is because of the shikimic acid, a substance that is not cheap at all and can be acquired only via star anise, Chinese spice. But I am sure they said last year that they no longer have any issues with that.
