Ok, so it's actually cooler than the title suggests. The gravitational lensing shows the same supernova at three points of it's life days apart - simultaneously. So three images around the galaxy at the same time, with varying degrees of brightness. Distances the light travels around the galaxy must be truly vast for such delays.

Long story short - they did an analysis of papers published on the topic, and found that people with double vaccination, or vaccination plus infection (but not single vaccination) had an 19% lower risk of getting long covid, as well as overall lower rate of complications like organ damage. Thus they recommend increasing the vaccination rates.
