It depends on the particular vaccine. Generally we can divide vaccines into two groups: live and "dead". Live vaccine contains weakened (attenuated) pathogen, which (in case of a virus) theoretically can infect our cells. However, as it is attenuated, it is not doing it very efficiently, thus even naive immune system has no problem with defeating it. "...

First of all a disclaimer, I am not an expert in this subject, but I have read these studies and came to this understanding. There might be a chance I get a lot of stuff wrong. From another paper by the same authors, this time regarding 222nm UVC: We have previously shown that 207-nm light emitted by a filtered krypton-bromine (Kr-Br) excilamp has ...

No known viruses directly infecting humans and insects. Few bacteria though - not many people care about sick insects. Yersinia pestis causes plague in humans (and some other mammals) and in the Oriental rat flea can block the foregut - but I dont know how bad that is for the flea. There are some similar genera (groups) of bacteria in and on both hosts; ...

This is a great biological question! It asks a lot about how empirical science is done in the field of modern biology! I'm glad we encourage such questions from curious people who want to learn more. There is another paper here that discusses using a similar frequency range of UVC radiation (207-222 nm) as a biocide: The biophysical reason is that, due ...

There is not really an inherent difference between these viruses. Polio is a run of the mill enterovirus - some of its closest relatives are "common colds", while others are less pleasant - see https://www.slideshare.net/TarekMahbubKhan/enteroviruses-and-polio for some examples. Note that some "common cold" viruses have uncommon but nonetheless devastating ...

There are plenty of diseases that affect insects, Dicistroviridae is one. There are also plenty of fungal & bacterial ones, it's just that they aren't generally of concern to us so study of & information on them is somewhat light. If you Google 'insect disease' you'll likely just get links for human diseases they're vectors for. If you want to ...
