It is never the scientists that win an argument with the executives running pharma companies, never.I think it has been widely publicised that production of likely candidates is already well underway. Also, the community working on the vaccinations would be having a general understanding of success or otherwise of their trials, well before the scientific processes and reviews are completed.
Equally, the history of scientists being bought & paid for by industries is vast - asbestos, thalidomyde, tobacco and much more close to home in Australia - PFAS.
As pressure for coronavirus vaccine mounts, scientists debate risks of accelerated testing
Drugmakers are working as quickly as possible to develop a vaccine to combat the rapidly spreading coronavirus that has infected more than 100,000 people worldwide.

Studies have suggested that coronavirus vaccines carry the risk of what is known as vaccine enhancement, where instead of protecting against infection, the vaccine can actually make the disease worse when a vaccinated person is infected with the virus. The mechanism that causes that risk is not fully understood and is one of the stumbling blocks that has prevented the successful development of a coronavirus vaccine.
Normally, researchers would take months to test for the possibility of vaccine enhancement in animals. Given the urgency to stem the spread of the new coronavirus, some drugmakers are moving straight into small-scale human tests, without waiting for the completion of such animal tests.
Hotez worked on development of a vaccine for SARS (Severe Acute Respiratory Syndrome), the coronavirus behind a major 2003 outbreak, and found that some vaccinated animals developed more severe disease compared with unvaccinated animals when they were exposed to the virus.

The plan is consistent with the WHO consensus and FDA requirements, said Dr Emily Erbelding, director of the Division of Microbiology and Infectious Diseases of the National Institute of Allergy and Infectious Diseases (NIAID), part of the NIH. The trial is expected to take 14 months, a spokeswoman for the NIH said.
Dr Gregory Poland, a virologist and vaccine researcher with the Mayo Clinic in Rochester, Minnesota, expressed doubts about that approach. “This is important, but it has to be done in a way that reassures scientists and the public that these (vaccines) are not only efficacious, but safe,” he told Reuters.

Research, including that conducted by Hotez, has shown that coronaviruses in particular have the potential to produce this kind of response. But testing for the risk of vaccine enhancement is time-consuming because it requires scientists to breed mice that are genetically altered to respond to the virus like humans. Work on these and other animal models is just getting under way in several laboratories around the world.
Moderna, Inovio and several other vaccine developers are not waiting for that process to be completed and are planning to launch human trials in record time for a virus that was only discovered in December.

The concern is that the time frames initially spoken about for 'sped up' development processes talked of 14 to 18 months from the start of the first human trials.
Now the message has been modified. Remember up until CV - no successful vaccine has ever gone from inception to delivery in under 4 years. Even 14 months seems a stretch.
14 months would have made the earliest entry into use June 2021 for the 1st vaccine candidate - and is what the graph I posted documents. The graph is as of late August - so up-to-date on the 'sped-up' time frames. None show entry into use by end of Q1 2020.
The issue with attempts previously for different CV vaccines (SARS etc) is that every one caused worse outcomes in 'some people'. The rate of worse outcomes was greater than the lifes expected to be saved.
The proponents claim it is 'unlikely' to be a problem as the vaccine development this time 'is different'. Normally hope is not a bankable investment in peoples' future other than when science has failed.
