The post is conflating vaccine efficacy and effectiveness which are two different epidemiological measures.

It also fails to consider the false positive and false negative rates inherent in these studies. In particular, lots of asymptomatic cases in the vaccinated arm are not caught by efficacy studies (false negatives). So claiming that low death rates are solely a result of reduced infection(as opposed to fighting off infections better) is also a conclusion made hastily.

Death rates and symptomatic cases are much measured much more accurately, and claiming that effectiveness studies have little point once there's vaccine efficacy is available underestimates the challenges of epidemiology.

But the overall point that statistics are hard to understand, easily misused in online arguments is a valid point.
