There’s an argument that covid vaccines don’t block the virus from being contagious.

Off the top of my head, doesn’t it make it less contagious due to your immune system nipping it in the bud?

In other words the virus has less time to incubate and infect others because your immune system knows what to look for. 

Octopodes is certainly more valid than octopi. the "-pus" suffix is Greek and therefore should be pluralized to -podes, whereas cactus -> cacti, hippopotamus -> hippopotami, etc., have roots in Latin. However, since the first recorded use of the word "octopus" was in the 1759, I am equally comfortable using the traditional English pluralization of "octopuses"
