Vaccination is definitely not a waste of resources, unfortunately though, the vaccination rate is pretty low, with only a few exceptions. Israel's case is fascinating though, it has already vaccinated at least 40% of its population and has already noticed great results, fewer cases, deaths and less severe incidents.
It's also slowly reopening its economy, with the vaccination program running, it won't take long to achieve a decent percentage of immunity.

Among the larger countries, the United Kingdom is the best example. They have already vaccinated around one-third of the population, and this has seen the daily number of deaths falling by more than 99%. The United States has also vaccinated close to one-third of its population, and the deaths there have fallen (although not as much as the case in UK).
That is also correct, the United Kingdom had already signed contracts with Pfizer way before the European Union did. As a result, the first batches were distributed in the UK and conducted a large amount of vaccinations. If I've read correctly, the deal was made 3 months before the EU did, that's why we're now facing shortage issues.
