This graph shows only the rate of infections increasing during the peak annual rate of due to weather and other factors. You need a graph with before vacines and the rate os infections and severety of the dicease, versus after vacines. Only then there will be correlation to see wich system is better. This is erroneous data validation to support a single point of view.
Discussion
You have valid points. I'm just highlighting an obvious and anecdotally observed pattern. Our eldest had the day off on school vax day. Shortly afterwards it seemed all kids got unwell with fever and cough for at least a week. Nationwide reports of flu spikes since. I've subsequently had similar symptoms for the last 10 days. The new Flumist nasal vaccine they were using is a LAIV (Live Attenuated Influenza Virus).
Correlation of the recent flu spikes with mass child flu vaccine is not proven or disproven. Nonetheless, certainly doesn't seem like an effective vaccine at reducing relevant current strains.
I'm not an expert. But my understanding of vaccines (flu and COVID at least) is to give better change of fighting the virus after infection, and not to prevent infection from happening.
I wonder if the nature of the vaccination process (kids all rolling into the same room) created the favourable environment for spreading of the flu?
