- Authorities have declared
a public health emergency.
- We do not need that many vaccines.
- There's a lot of
misinformation out there.
- The measles is back,
almost 20 years after it
was considered eliminated
in the US.
And it's tied to a decline
in vaccination rates.
So why are so many parents
choosing not to vaccinate their children?
(upbeat music)
- Hey guys, you're watching Trackback.
Today we're debunking
common myths about vaccines
and trust me, there's a lot.
One common for false belief
is that the MMR vaccine causes autism.
MMR vaccinates against
measles, mumps and rubella.
There is no proof it causes autism.
One study on the MMR vaccine
reviewed a huge amount of research
involving 14.7 million children
who received the vaccine.
And they found no link between
the MMR vaccine and autism,
or any of these other diseases.
Asthma, leukemia, hay
fever, type 1 diabetes,
gait disturbance, Crohn's disease,
demyelinating disease or
bacterial and viral infections.

- This myth originated in a 1998 study,
but it was later retracted.
The study was done by Andrew Wakefield,
but the UK's General Medical
Council found him guilty
of serious professional misconduct,
and he lost his license to
practice medicine in 2010.
- Beginning in the 30s,
vaccines used the mercury-containing
compound thiomersal
as a preservative.
This makes some people think
that vaccines are toxic.
But hundreds of studies proved
the amount of thiomersal
in vaccines does not
pose any risk to humans.
Plus, in 2001,
thiomersal was removed from
most children's vaccines.
Next, some people believe too
many vaccines at a young age
can overwhelm the immune system.
But there's a reason
why vaccines are given
to babies and toddlers.
They have a very active immune system.
They're exposed to hundreds
of foreign substances
that trigger their immune
response every single day.
That's a good thing.
Plus babies are exposed
to far much antigens
from a common cold than
they are from vaccines.
Another belief is that a parent's decision

Another belief is that a parent's decision

English: 
to vaccinate their child is personal
and makes no difference to anyone else.
We get why people think this,
but if you choose not to
vaccinate your children,
you're also putting everyone
around them at risk.
In communities with
high vaccination rates,
diseases don't spread as quickly
due to a process known as herd immunity.
If everyone in your
neighborhood is vaccinated,
an outbreak is likely to be
contained rather than spread,
but when people voluntarily
stop vaccinating their children,
the herd is broken up,
allowing diseases to
spread much more quickly.
Herd immunity is critical for people
that legitimately cannot be vaccinated
due to a medical condition,
like a life-threatening allergy.
Another concern is vaccine injury.
Yes, vaccines do come with risks,
but the reality is you're much more likely
to be seriously injured by a
vaccine-preventable disease
than a mild vaccine side effect.
From 2006-2017, there were
over 3.4 billion vaccines
given out in the US.

But the National Vaccine
Injury Compensation Program,
which awards money for vaccine injuries,
only paid out 4,300 cases.
This means for every one
million doses of a vaccine,
there was just one reported injury.
So while you may experience soreness,
redness, swelling or mild fever,
that's nothing compared
to contracting measles.
- Since January 2019,
there have been 1,123
cases of measles declared
in the United States.
That's the highest
reported number of cases
since the disease was
eliminated almost 20 years ago.
- At the end of the day,
parents believe they're doing
what's best for their children
but the stakes are really high here.
So make sure you and your
family use credible sources
when searching for medical
information online,
like the Centers for Disease
Control and Prevention
and the World Health Organization.
Trackback tip.
If you know somebody that
has doubts about the safety
or necessity of vaccines,
research shows that positive
messaging from trusted sources
works better than shaming someone.
