There would be lots of contenders for biggest farce in this affair.
In Canada, where our government says it "follows the science" they have now decided to wait four months between the two shots, rather than the recommended one month apart. Why are we doing this? Because doing so will allow the government to "vaccinate" twice as many people with the same amount of vaccine as they would have otherwise. Thus Canada's failure to secure vaccine in a timely fashion can be hidden! Science is so helpful!
Here's another contender for 'biggest farce.' The EU has secured millions of doses of the Astra-Zeneca vaccine, but it was recently determined that that vaccine should not be given to people over 65. So those millions of doses are to be used for people under age 65. But the EU has a system for vaccinating people, and under 65's come after older than 65. So even though they have vaccines that aren't of any use to the over 65s, they refuse to use them for thunder 65s. Those vaccines are sitting in warehouses pushing expiry dates . . . .
For what it's worth, Canada has decided that over 65s can get the Astra-Zeneca vaccine, regardless of the science, because the number of people receiving the vaccine is more important than the efficacy of the vaccine for those people.
None of this matters at all though, because "we're all in this together!"
Isn't it nice when science follows the politics?!!
