Its not just transplant patients... its most cancer patients too...
From what i gather from the london teaching hospital and the oxford guys, it normally takes:
2 to 5 years in discovery phase on what to look at - apparently this has been essentially done over the last 10 years as they have been doing work on sars1 and coronaviruses for years. the flu vaccine is changed every year to cope with mutations so
my understanding is that this 2-5 years has already been crushed from prior research on the viruses.
I gather therefore that from stage 2, trials take about 2 years to assess and understand immune response. From stage 3, then it takes 5 years to understand how long the immunity lasts in the mass population. My understanding is we are at stage2/3 but that is not such a safety issue as this has been done over the last 10 years, as to an understanding issue as to whether they actually provide immunity over what time period.
Moderna is on stage 3 already 10 years in from Sars1, and has recruited 8374 volunteers and is hoping for 30,000 imminently.
Sanofi makes the flu vaccine so is also already a long way in with GSK. These guys are not starting from scratch.
But generally speaking i agree vaccine uptake is only significant when people you know start dying. On the spanish flu, then the elderly died to start with; the young died the following winter. If that happens with this, we will all be thankful for both a vaccine and interferon beta.
