Directly from the CDC.
The period when an infected person is contagious depends on the age and health of the person. Studies show that most healthy adults may be able to infect others from 1 day prior to becoming sick and for 5-7 days after they first develop symptoms. Some young children and people with weakened immune systems may be contagious for longer than a week.

So yes, you are contagious before you get symptoms.
So I'm thinking about this period of time right here, when only a fraction of people have been vax'd and there is not enough vaccine to go around. Even if I plan on getting the vaccine in the future when it's available to such as I (I am certain I won't be part of any eligible group until 2010.), there is nothing I can do about spreading the germ or not, whether I have natural immunity and never get symptoms, or right up until the moment I do get symptoms, to prevent someone else from getting it from me.

So why even bring that up in the argument? As if it impugnes the people who are not inclined to get the shot in the first place, when in fact, it applies to everyone vaccinated, post-flu and well again, or not vaccinated at all. It is irrelevant.

I CANNOT get the vaccine, so there's no point in me doing anything different except be mindful of my sanitary practices. The suggestion that I should stay inside is ridiculous and unnecessary.
