Fact or fiction?
You can get the flu
from the flu shot.
00:04
You don't know how many
people told me this.
00:06
Oh, I got the flu shot once
and then I got the flu.
00:09
So I'm not ever doing it again.
00:12
This is fiction.
00:14
Let me explain why.
00:17
The flu shot is
inactivated virus,
so you're not able to
get the flu from this.
00:23
Now am I saying that the
patient didn't have the flu?
No, but it takes a couple weeks for
your body to develop antibodies,
so the patient may
have picked up the flu
even before they
got the flu shot.
00:35
So keep that in mind.
00:38
Now what about is the
flu shot 100% effective.
00:43
No,
the flu virus is constantly
changing into new strains.
00:48
They call it mutating,
and we make predictions
long before flu season.
00:53
So keep this in mind.
00:54
Yep, you could get the flu shot
and then even after
your body has antibodies
the patient develop the flu
so it isn't a hundred
percent effective.
01:04
So when people tell you
that, that is right,
if they said they got the flu vaccine
and then later on they got the flu
they could be absolutely spot on
what can't happen
is the flu vaccine
did not give the
patient the flu.
01:20
So hundred percent effective.
01:21
Let me break it down a
little bit for you there.
01:22
It takes 10 to 14 days for
antibodies to be created
that can fight off influenza.
01:29
So you get the flu
shot the vaccine,
then it takes your body
like a couple weeks
before I can develop
the antibodies.
01:36
Remember antibodies
are going to recognize the
flu virus as an invader
and take care of it,
but it takes a while for your
body to do all that programming
and get prepared
for the flu virus.
01:48
So let's talk about how the
yearly vaccine is selected.
01:52
I want you to be educated and be
able to make an informed decision.
01:56
We have more than a hundred
national influenza centers
in over a hundred countries
that collect data year-round.
02:03
So this just isn't a guess.
02:05
This is a very
highly educated guess
based on data.
02:10
Now samples of the virus are sent
to five who collaborating centers
for reference and research
just on influenza.
02:18
So the hundred centers
send their samples to
these five WHO centers.
02:23
Let me show you where
they're located,
Atlanta, Georgia,
London,
Melbourne, Australia,
Tokyo Japan,
and Beijing China.
02:33
So these five centers are
participating in that research
and the development
of the vaccine.
02:38
Now the World Health Organization
often hurt called the WHO,
assesses which strains
of the flu virus
are most likely
to be circulating
in the northern hemisphere
in the following winter.
02:51
Now then they will make a
recommendation which flu strains
should be included in the
vaccine and each country.
02:58
Okay underline that.
02:59
Each country makes
the final decision
which strains will be included
in the licensed flu vaccines
in their country.
03:08
Have you ever gone
for a flu vaccine?
Make sure you always ask
some are trivalent meaning
three strains of the virus,
some are quadrivalent those contain
four strains of the flu virus.
03:21
So if I'm getting
the flu vaccine,
I'm definitely going to get
the one with four strains.
03:26
So you got the process,
hundred centers
collect the data,
then they send it
to five WHO centers
and these multiple countries
that analyze the data,
the WHO makes a recommendation
but each country is on who
makes the final determination
of what will be their
official flu vaccine.
03:45
Now most years one or two strains of
type A flu and type B flu circulate.
03:52
The Food and Drug
Administration the FDA
makes a decision in
the United States
which strains will be
included in our flu vaccine.
04:00
Vaccine production starts in
March and it's ready in September,
remember it takes 6 months for
large quantities to be produced.
04:09
So it takes a while to identify
what should go in the vaccine
and then to actually
produce the vaccine.
04:17
So they start in March for
the very next flu season.
04:24
Antibodies are large
y-shaped proteins
that are produced by the
beta cells in the plasma.
04:31
Okay so these are the things that took
10 to 14 days to get ready. Right?
We need these because
they recognized a bacteria
or in this case a
virus as an antigen.
04:41
They recognize what
an Invader bloodstream
and they neutralize the antigen.
04:46
That's what antibodies do
but it's not instantaneous.
04:50
Remember I want to keep reinforcing
that it takes 10 to 18 days
after the vaccine is received
for the body to create
these antibodies.
04:58
So viruses are hard to kill
without harming the host.
05:02
Yeah,
because the virus is pushy.
05:05
They get right into your cells.
05:07
They overtake your cells
and make your cells
start replicating viruses.
05:12
It's different than bacteria.
05:14
They are much
easier in most cases
for us to kill with antibiotics.
05:19
Vaccines are actually the
best way to prevent the flu.
05:22
We I'd rather help
your body be prepared
before it's exposed to the flu
rather than try and fight
off the symptoms afterwards.
05:30
So antibodies are
a key component
of our adaptive immune system.
05:35
Yeah, sounding familiar.
05:37
This is things that
my body responds to
to help keep me safe.
05:41
That's an amazing property
of our immune system
of how it can adapt.
05:46
So people who receive the flu
vaccine developed antibodies
to those particular
strains of the flu
that are in the vaccine
in approximately 10 to 14 days.
05:55
Yep. I've said that a lot
because this is the one thing
I want to make sure you know,
when you're educating patients, when
you're talking to your family and friends,
know that that vaccine is
not going to be workable.
06:07
It's not going to do
what you want it to do
for two weeks.
06:10
That's why if you're
going to get the vaccine,
you want to get it fairly
early in the season.
