Oops, that's definitely what I meant. Thanks for pointing out the error! I was one of those weird people who had chickenpox on only one half of my body. I made sure to get the shingles vaccine, since getting chickenpox on the other half as an adult is a worse experience.

P.S. We get so many diseases by inhalation, it seems like more vaccine delivery mechanisms should be nasal. I know different places are working on one for SARS-CoV-2, but apparently working with live virus is tricky.
