So, to expand further. The programme (ably assembled by @BBCFergusWalsh) highlighted issues of global vaccine inequity. This is undoubtedly a major challenge and will continue to be so.
However, we need to adopt a new model of production and distribution. As the programme wonderfully illustrates. GMP manufacturing capability is incredibly imbalanced, with a few places (like US, UK, Europe, China, India) having the lion's share.
This means that too many low- and middle-income countries are reliant on those places 'doing the right thing' and providing equitable access. But there is a different way.
'Teach me to fish and I will eat for a lifetime...'
One of my past projects was focussed on getting HCV biologics to clinic and required collaboration with process developers and biologics manufacturers. One of these (univercells.com) had biologics for all at the heart of its mission.
This is not an advert for them - I'm sure other companies out there are trying to do similar. I raise it to show that we need to think of different ways of improving accessibility to biologics and other medicines.
Their mantra was to provide easy to use, small- to mid-scale manufacturing capability to low and middle income countries. To provide training and know how and then leave them to be self-sufficient.
Then, with appropriate licensing arrangements, most, if not all countries would be able to make their own. It wouldn't work for all vaccines and treatments, but it would certainly make more sense than over-reliance on a few key makers. Just saying...
One final point. It's been a while since I worked with Univercells and their business model might have changed. What I have relayed above is the model they were pursuing at the time of our interactions: Parachuting in tech and know how, then encouraging self-sufficiency.

Therefore I will append a clarification that my comments were able the status quo and covid vaccines alone and any other points I thought relevant to ensure my musing can't be misconstrued. The overall point about global vaccine inequities and emergence of variants remains, but
My comments hopefully can't be taken out of context and used nefariously by others with an anti-vaaxx agenda or similar. I have always been and remain a staunch believe proponent for vaccines. However, we need to understand what they do.
I don't know why I (and many colleagues) have to keep saying this but #COVID19 vaccines do not prevent infection and therefore do not prevent emergence of variants. Sub-sterilising immunity through infection or vaccination will drive emergence of variants.
Please don't use this line of argument to underpin vaccine equity statements. Vaccine equity is important. Very important. But it should not be argued that fairer vaccine access will protect the world from future infections or variants.
It is possible to generate sterilising immunity but incredibly difficult to maintain. Therefore, we need to accept that infections will continue in future, variants may well emerge.
It's great to see that the important role of #technicians in teaching and research is being acknowledged and that measures and policy are being put in play to support them into the future.
However, I still think that research councils, universities and research institutions are still ignoring the elephant in the room that is the thousands or short-term contracted research staff, without whom UK research really wood collapse...
Career pathways for these guys really hasn't changed throughout my career, and it really needs to. Even permanency of employment rules don't seem to have teeth, as their roles are still all-too-often tied to duration of research grants...
Didnt get chance to answer a great Q on @sarahjulianotts show on @BBCNottingham about having #COVID19#vaccine the starting #immunotherapy. If the therapy is designed to dampen down your immunity, then it might reduce the overall level of immunity that the vaccine produces.
But in this case, the therapy will start 14 days after vaccine, by which time immunity has often peaked (with Pfizer, maybe slight increase with AZ after this time). Therefore, the therapy will have very little, if any, impact.
And if you are currently on immunotherapy, then the vaccine committee have not precluded you from having the vaccine. Even if the overall response is reduced, I think in most people it will still offer some protection. Worried or unsure - ask your clinical orvaccination team👍
@Psynian 1/n
Not sure I align to his views.
The virus is mutating, there is evidence/suggestion that some of those might change virus behaviour. There’s a spike change (amino acid 614) that increases infectivity of virus when grown in the lab.
@Psynian 2/n
But we don’t know if this increases infectivity, disease severity or transmissibility in humans.
@Psynian 3/n
There’s also a deletion that removes one of the non-structural genes (ORF8), which is thought to down regulate antigen presentation. nature.com/articles/s4157…
Thanks to @JanetDaly5 for flagging this. First animal data from #chadox1#SARSCoV2 vaccine. Not sterilising immunity, but reduced viral load and pathogenesis, with half dose, BUT very quick challenge 4 week. (recall questioning this previously): biorxiv.org/content/10.110…
1/n worth considering these data in detail; and what they might or might not mean
2/n Firstly, the challenge dose. This was a relatively large amount of virus, BUT for people exposed to virus for considerable periods of time and/or large amounts (household member or healthcare worker) then protection against higher viral load exposure is relevant.
