No it doesn't. That is not a scientific observation at all and your perfectly round numbers are completely made up.
A novel disease is most potent when it hits populations with no built in immunity. The disease hit elderly people particularly hard. Among those that survived the first wave of covid, people built up natural immunity.
I said it would be a good case study, which would be an element of research trying to establish the effectiveness of the vaccine. Obviously what I presented here is not science, and I didn't claim it was. Science is one tool of many that we can use to observe reality and try to draw conclusions about it. It's not the only tool, and you shouldn't discount one tool for not being another tool.

5 deaths in Dec 2020 up to 94 deaths ~100 deaths. Cases were ~1000 in December 2020 and went up to ~4000 in February, an increase of ~3000 cases. Infections leveled off and started increasing in June from ~4000 to exactly 7248 today, an increase of ~3000 cases. During this outbreak, exactly 4 people have died.

Maybe. Or maybe the vaccine is doing in the wild exactly what scientists found it did in their vaccine trials? Occam's razor would say to go with the vaccine as the explanation due to it requiring fewer assumptions (we know everyone is vaccinated, we don't know what proportion of that population has built up immunity by contracting Covid naturally).
