How does it apply to our situation, where we've been lied to about the number of "positive tests"?
Were people who's specimens were PCR'd to the 40th power actually sick?
Is the "vaccine" really contributing to the reduction in cases?
Looks to me like the Biden Inauguration was the real turning point for the corrupt data.
The RT-PCR test is a laboratory diagnostic tool used to determine whether SARS-CoV-2 is present at the point of collection. For those individuals who test positive with an RT-PCR test, the virus is present. When you say "actually sick", what you're looking for is a clinical diagnosis based on symptoms. The case definition for COVID-19 is looking for either one. 40% of COVID-19 cases (per the US CDC case definition for COVID-19, linked above) are asymptomatic, meaning they present no outward symptoms. 40% have mild symptoms, similar to a cold or allergies. 20% require some medical care. 5% become hospitalized. 3% go to the ICU. 0.65% die. Those numbers are a little old as some effective therapies (mostly monoclonal antibody therapy) are helping to reverse the course of the most severe cases.
"Is the "vaccine" really contributing to the reduction in cases?"
Not today's drops, no. We're at the end of the holiday wave. Most of the world experienced the same wave. What the vaccine does is prevent future waves and drive us to herd immunity. It also prevents variants like the South African variant from spreading among those who had mild or asymptomatic cases, as their levels of neutralizing antibodies are potentially too low to provide adequate protection against that one particular variant.

The rates of new cases and new deaths followed the same bell curve path in the US and every other country, for each wave of this infection. It's the same basic curve seen in any disease where you have periodic outbreaks followed by lulls as conditions alter the virus' ability to spread. Joe Biden hasn't done anything to help matters. President Trump's Operation Warp Speed certainly did. With the help of the vaccines, we'll reach HIT some time in July and this thing will be over and done with.
