Did guns or vaccines save more lives in 2021?

[FlatAssembler]

COVID-19 vaccinations are estimated to have saved around 300'000 lives in 2021 in the USA.
According to the famous study done by Gary Kleck in 1995, guns also save around 300'000 lives each year in the USA.
So, what do you guys think, did defensive gun use or COVID-19 vaccines save more lives in 2021?

There were something like 20,000 murders or criminal homicides in the US each year.   for guns to save 300000 lives a year, we would need to assume it prevented 94% of the murders or homicide that otherwise would have occurred.  it says were it not for guns the average american would have roughly 1 % chance of dying from murdered or homicide.   it also says guns are not only available for, but also successfully used for, self defense in 94% of the cases where the intended victims would otherwise have been killed.   do any of this pass the most cursory sniff test even for the US?    

Since I think Gary Kleck’s study overstates the life saving value of guns by only a slightly fewer orders of magnitude than Bishop Ussher’s study understates the age of the earth, I would say Covid-19 saved far more lives.

I don't know. I am Croatian, not American. I only know USA is a very high-crime country.
