The first major "real-life" study is out on the Pfizer and Moderna shots and, not surprisingly, they are still extremely effective against not just the original strain of the virus, but also the various mutated strains that have followed in recent months.
The study followed roughly 4,000 frontline workers and found that either shot was 80% effective shortly after the first shot and 90% after the second.
The light at the end of the tunnel is continuing to get brighter.
