Same difference. "There is no downside to any vaccine" means at any time, if you see a label that says "vaccine", it's never a bad idea for you to take it.
I'm not claiming any expertise here, but some examples:
The jannsen covid shot: you're likely to come in contact with covid, this one is only recommended for folks who can't do mRNA for whatever reason. (The same concept applies to any vaccine that isn't considered the best of its kind)
HPV: not just blanket recommended to everyone, yet you are very likely to come into contact with HPV.
Chatgpt comes up with plenty more examples, but the concept is simple. Just because something is called a vaccine (or medicine in general) does not make it some kinda special power up that everyone should be maximizing their exposure to.
