Perhaps the researchers would like to spend a little time figuring out how to 'democratise', de-politicise and remove the greed factor that males the likes of Pfizer and others hold poorer, developing countries to ransom.
Other flaws that need addressing are consistent population management practices, education/information and removal of class privilege regarding masks/distancing and assembly numbers.
The haphazard management of the entire pandemic gives so much fuel to the dissenters and anti vaxxers that it is a joke.
Some honest reporting from governments would go a long way too.
