It is not really a contradiction, although I question his wording.  He is
saying that no vaccine prevents you from getting the germs, but they do
help your body fight off actually becoming ill.

So, people vaccinated for a disease might get the germs, and might even be
able to spread it during the time between contact and fighting it off.
Some vaccines are nearly 100% effective at preventing illness while others
are not... usually because the infected person caught a new or reintroduced
strain not covered by the last vaccine they got.

I 100% believe all this "vaccines are bad" and "germs don't exist" nonsense
has happened because there are a large number of Americans (me included)
who are not old enough to remember what life was like before vaccines were
introduced.

People who are old enough to remember are damned glad that they never had
polio, measles, mumps, etc., because they *knew* people who did, and most
of them are damned glad there were vaccines introduced that nearly or
completely irradicated those diseases from the US.  Those of us not quite old
enough never lived in a world where those diseases were common.  We take
for granted that we can "never catch them" and apparently some of us have
become comfortable enough that we question whether or not they even existed.
