AstraZeneca and Oxford's Stories Clash on COVID-19 Vaccine (reuters.com) 56
AstraZeneca and Oxford University have given conflicting accounts of how they came upon the most effective dosing pattern for their COVID-19 vaccine, a rare instance of public dissension between major institutions collaborating on a pivotal project. From a report: The discrepancy, reported for the first time by Reuters, centres on the regimen administered to a smaller group of volunteers in the late-stage trials, of half a dose followed by a full dose. This diverged from the original plan of two full doses, given to the majority of participants. The half-dose pattern was found to be 90% effective, versus the 62% success rate of the two-full-dose main study, based on interim data. AstraZeneca's research chief told Reuters 10 days ago, when interim trial data was released, the half-dose was given inadvertently as a first shot to some trial participants, and emerged as a stroke of fortune -- "serendipity" -- that scientists expertly harnessed.
This narrative was refuted by a leading Oxford University scientist, however, who told Reuters on Monday that the half-dose shot was given deliberately after thorough consultations. Uncertainty over how the dosing regimen came about raises questions about the robustness of the data, according to some experts who said it risked slowing down the process of gaining regulatory approval for the shot and denting public confidence. "These differing accounts are worrying," Eleanor Riley, a professor of immunology and infectious disease at the University of Edinburgh, told Reuters. "Trust is at a premium when it comes to vaccines and we must not do anything that might in any way undermine it."

In this case, the also changed the age of the test subjects. It is mostly more effective when given to younger people, nothing to do with full or half doses, just younger people. The vaccine is the the most dangerous, for those most at risk from the infection and provides the least protection for them. That is what the study really did prove but hey, billions in profit.

Well then wait before you get the vaccine. I think it's pertinent to point out that the first recipients of the vaccine are those in the most at-risk groups, and the high death rate amongst these groups arguably presents a higher risk than the possible dangers presented by a vaccine that has already passed stringent phase 3 trials. And I put far more trust in a vaccine developed by Pfizer/Astra/Oxford than one that could have suffered political pressures from authoritarian regimes.

There was the Rotavirus Vaccine in 1998. It made it all the way through approval and was released but then soon thereafter pulled from the market voluntarily because it caused bowel obstructions in babies.
There was also the MMR vaccine in 2005 but it doesn't sound like the side effects were life threatening, just worse than the alternative MMR vaccines so there was no reason to use an inferior product when safer alternatives exist.
Everything is always a cost/benefit weight in life. I suspect considering the absolutely astronomical cost in lives, health and cash of covid19, the price regulators are willing to pay is high as well relative to new flavor of MMR.

When considering just how many vaccines there are, and how many people are vaccinated, the short answer to that is "rarely". For a more numerical, though still by no means full, answer you might like to have a quick read of this page [historyofvaccines.org] which gives specific 'probabilities' of the various side effects for one specific and widely used vaccine, as well as some context on the relative risks, and links to other resources.

Yeah, and you can imagine the immense pressure they were under to spin the news, given how crappy their vaccine is compared to the mRNA ones. The mRNA vaccines are nothing short of incredible, but it's pretty clear from the pre-orders that there was a lot more scepticism about them working compared to the other approaches.

The actual quote from the earlier Reuters article [reuters.com] is "The reason we had the half-dose is serendipity." If they expected a full dose for both shots, but got a half dose from a new manufacturer, and yet the half-dose turned out to work better, that would be serendipity.
Now Oxford University is stressing that they noticed the difference first and went through channels before actually administering the half-dose portions. Yeah, I hope they did that -- otherwise they should be told to clean their desks, and when they're done, the nice chaps outside with handcuffs would like a word. But that does not address why they had half the dose in the first place.

When we hear the term "conflicting accounts" we automatically think someone must be lying, but it can also be a case of the left hand not knowing what the right is doing or why.
If, as the Oxford group says, they made a deliberate decision to try the half dose protocol after consultations, I'd tend to believe them, since the existence of those consultations should leave some kind of record keeping trail.
The number of subjects on the half dose regimen was relatively small (2700 out of 41,000), so it may not h

The half-dose was given to the younger people, the full dose to the older [bloomberg.com]. So we don't know if the effectiveness discrepancy is because of the age of the recipients, or that that giving a lower dose is somehow better.
...told Reuters on Monday that the half-dose shot was given deliberately after thorough consultations
That doesn't sound right. Why would you give group A one dosage and group B another dosage, when group A and B are different age groups? You now have no control with which to determine the rather significant difference found in the effectiveness. That article I just linked to implies there is some age overlap though, so maybe they can split the data out for the overlapping age range and determine if it was the dosage or the age. But it sure does seem odd that a lower dose would be more effective, buuut maybe that's valid...? Either way, this doesn't sound like something you would do on purpose. Hopefully all will be revealed in time.
