So you have all rights to be a little bit schizophrenic.

Not unless you think with with contents of your colon - the cells there may affect the hormone levels in the body as a whole, which can bias your thinking, but there's probably not enough processing power down there to support even one extra personality.

There is enough effect from the chemicals released by those bacteria to
have a very significant effect on your mood or personality.  Big swings
in your gut fauna can cause significant psychological effects, and may
well be a factor in schizophrenia (which has nothing to do with multiple
personality disorder).

  You're always sitting on your head and you seem to find sufficient 
processing to post this non-sense, or most of what you post that is.

What Jamie can't understand he finds to be non-sense. This is understood by everybody except him. He blames the rest of us for not simplifying what we write down to his level, and misses the point that it's the stuff that he can't understand that makes it interesting.

That's mostly the bugs in your gut, and the original calculation seems to have been done on the back of an envelope, and isn't any too reliable.

A ratio of 10 to 1 of gut bacteria to human cells was the original
estimate.  More refined estimates are lower, but it still outnumber
human cells significantly.

I was very surprised when I first heard this, but it seems to depend on 
the fact that bacterial cells are much smaller than human cells. 
Otherwise I think we would be *very* aware of the huge number of foreign 
cells in our body.

From what I learned from my ITP, is that antibodies have a 26 day
half-life. After you fight it off you still have antibodies in force
for 3 months and after that you have still have some in your system.
They may change their type but are availible to fight future
infections.  Just like getting a vaccination.

Cheers

Unlikely that's a direct link. Each year's vaccine
is an educated guess as to which flu variant (the
HxNy thing) might be around in ~1 years time.

I seem to end up slightly sniffly after the flu vaccine.
I don't get it for /my/ benefit, but to protect my mother
from catching it when I visit her.

She has the vaccine and doesn't have any symptoms.
There's no justice :)

I'm not sure why people think getting a live vaccine won't have 
symptoms.  You are being injected with a virus that is weakened enough 
that you won't get a full blown flu, but it is entirely possible that 
you will have some of the symptoms.  Many symptoms of an infection are 
not a direct result of the infection, but from your body fighting it 
off.  You should expect to have some of those same symptoms from a 
vaccine as your body responds to it much like it would to the flu 
itself.  Some vaccines cause mild symptoms like a rash around the 
injection site or a scab and if these reactions are missing the vaccine 
didn't work.

Just so.

I've had reactions to the flu vaccines and in 1981 to
cholera and typhoid.

In the latter my arm was tender/sore for 24 hours - probably
because the vaccines were stored in phenol!

I've avoided the flu one too and haven't had flu for over 40 years - 
until now. The flu I could have handled without too much hassle, BUT it 
weakened my immune system and opened me up to Shingles, which I'm still 
suffering the after-effects of. Shingles pain can be *excruciating* at 
times, I won't forget it in a hurry. Consequently, out of fear of getting 
shingles again, I plan to take care of my immune system in future and 
that includes getting the flu jab from now on.

I may succumb to taking the shingles vaccine... you're all scaring me
:-(

But still "NO" to flu vaccine.

Ask some of your friends if they have had it. One in three over 50 have had 
it. They will give you a reason.

You have a 30% chance of getting shingles without the vaccine. The vaccine 
is about 50 - 60 % effective.

It is a good deal!

Shingles really sucks, even a mild case. If gets in or near your eye, it can 
be tragic.

My wife had shingles a year, or so, ago.  She then got the vaccination
so she wouldn't get it again.  The vaccination was almost as bad as
the shingles.

   So can I deduce from this that, you don't develop immunity from 
shingles by having shingles?
  If that is the case, how does the vaccination work?

No, it's just a flare-up of the chicken-pox virus that are dormant in
the nervous system.  It can happen at any time.

>  If that is the case, how does the vaccination work?

I think the idea is to warn the immune system, again, so that it will
recognize another flare-up faster.  The disease is still in the
nervous system and can reemerge.  Not sure why a flare-up doesn't tune
up the immune system but it apparently doesn't.

"Immunity" is not an all-or-nothing sort of thing.  It's a
proportional thing.  The better your body is at recognizing "foreign"
antigens, and the faster it can gear up to product antibodies, and the
more correctly-structured the antibodies, the better the body can
resist the infection.

If you've had chickenpox, you very probably have "latent" virus
lurking in your nervous system.  You'll have developed antibodies
against this virus (and the specific B cells "programmed" to generate
them when stimulated), but the levels of both the antibodies, and the
number of properly-programmed B cells will decline with time.

If the virus comes out of latency, it will tend to spread along the
nerve fibers and cause shingles.  Antibodies seem to have some
difficulty working quickly against herpesviruses in the nerves (not
certain why but I suspect it's at least partly because nerves aren't
directly exposed to the bloodstream) and it takes a while for enough B
cells to "wake up" and start producing effective antibodies again.

This is why having had chickenpox, or an earlier outbreak of shingles,
isn't a 100% guarantee that you won't have a shingles outbreak... the
body's own immune system isn't fully effective.

The shingles vaccine acts to "re-prime" the immune system:  causing
enough of an immune reaction against the injected virus components to
"recruit" a new generation of properly-programmed B cells to create
antibodies against the virus.

This doesn't guarantee absolute protection against viruses which "come
out of latency" and start to spread along the nerves, but it does
help.  If I recall correctly, the vaccination reduces the number of
shingles attacks by about 50%, and also helps to reduce the severity
of those outbreaks which do occur.

It's sorta like doing a good warmup before going for a run.  Doing
your warmup properly doesn't _guarantee_ that you won't pull a muscle
or tear a tendon, but it significantly improves your odds.
