First, any analogy between SARS-CoV-2 and smallpox vaccines is flawed.
As is common with infectious respiratory pathogens, the SARS-CoV-2 virus mutates fairly rapidly, with new variants constantly arising. This is a known characteristic of RNA viruses.
Smallpox, on the other hand, is a DNA virus. It shifts much more slowly.

As a consequence of the differences between SARS-CoV-2 and smallpox, long-lived (lifetime) immunity from smallpox vaccination is feasible but not from SARS-CoV-2 vaccination. (side note: A 2018 study by China's "Bat Lady" Shi Zheng-li noted that antibodies from SARS related viruses do not last long, indicating that even natural immunity does not last all that long, which makes a SARS-CoV-2 vaccine almost impossible).
Second, the SARS-CoV-2 "vaccines" ARE NOT VACCINES. They work so poorly that the CDC found the historical definition of vaccine ("provides immunity") to be "problematic", and so changed the definition on their website to one where vaccines merely provide "protection". CDC internal email communications confirm this.
