If a vaccine is approved

[BlueBlancmange]

Up until now I have assumed that even if one vaccine is approved, research into others will continue. However I didn't really think much more deeply about how this would be possible. Assuming one vaccine proves to be effective, then every one would ideally need to get that vaccine and so there would be no one left to continue trials using placebos with. This wouldn't be a problem if the first vaccine were 100% effective, but say we get one that is only partially effective how could there then be any way to conduct research into a better one?

This has suddenly concerned me. Am I misunderstanding something?

This isn't really any different to any disease where a potential new treatment comes along - you stop comparing against the placebo (no treatment) and start comparing the two treatments against each other to see which is more effective.

Phase 3 clinical trials can also be compared against each other to reveal which vaccines work best in specific cohorts, like the elderly or those with comorbidities.

The fact that vaccine manufacturers are going to charge in the export market just as they do domestically is what gives them an incentive to produce for export. The pricing I've heard includes discounts for lower-income countries and lower prices until the pandemic is over and it becomes a routine vaccination.

There was an article published recently in The Lancet about the SOLIDARITY vaccine trial being coordinated by the WHO to study a number of different vaccines simultaneously. It's quite interesting and addresses some of these questions. It's open access iirc - should be easy to locate via Google.

[quote WordWarrior]@NiceGerbil Hi. I find it quite literally amazing how easily people are brainwashed by propaganda through the mainstream media about Covid19, although fear and deception are very powerful tools for controlling people with. This is just another classic case of 'Problem, Reaction, Solution' by the Elite. One thing you can be sure of though - The vaccine will be voluntary at first, but it will also be linked to payment systems eventually. No one will be able to buy or sell anything without it, or travel without it, so inevitably it will become mandatory. Stop blindly believing what your government is telling you, and if you have an open mind, do your own research to discover the truth.[/quote]
You know when people stop being blind, open their minds, think critically and see the truth like you obviously have, then realise they need to spread the word, how come every single person knows that they must without fail parrot the sentence 'Do your own research'? Does the phrase just automatically pop into the minds of the kind of people who are capable of thinking for themselves?
