Vaccines are celebrated for their part in fighting disease. But, a growing group of people seems to believe that they endanger our health, instead of protecting it. The Internet is full of stories about allergic reactions, the onset of disabilities, and even death following vaccination appointments.

And, it's true! vaccines can have
side effects.
Let's look at how they work, and how dangerous they really are? Your
immune system is a complex army of billions of cells. Soldiers, intelligence
cells, and weapons factories. Every day, you're attacked countless times, but
your immune soldiers alone usually deal with that, so you don't even notice. If
an infection becomes serious though, our intelligence cells gather intel about
the attackers and activate our weapons factories. You know the weapon:
antibodies. They're like targeted missiles produced specifically to combat the
invader. Unfortunately, this process takes several days to complete. That gives
intruders a lot of time to do damage. Contrary to popular wisdom, what doesn't
kill you doesn't make you stronger. Our bodies really don't want to fight
serious wars over and over, so our immune system came up with an ingenious way to
get stronger and stronger over time. If we fight an enemy that is dangerous enough
to trigger our heavy weapons, our immune system automatically creates memory
cells. Memory cells remain in our body for years, in a deep sleep. They do
nothing but remember. When an enemy attacks for a second time, the slumbering
memory cells awaken, and order coordinated attacks and the production of
antibodies. This is so fast and effective, that many infections you beat once will
never make you sick again. You might even be immune to them forever, which
is also why little kids are constantly ill; they don't have enough memory cells
yet. And this beautiful natural mechanism is what we build on when we use
vaccines.
How Vaccines Work?
As great as memory cells are, obtaining them through infection is
unpleasant and sometimes dangerous. Vaccines are a way of tricking our bodies
into making memory cells and becoming immune to a disease. They pretend to be
a dangerous infection. One way of doing this is to inject invaders that can't
do harm. For example, by killing them, or by ripping them into pieces. Our
immune systems deal with these kinds of vaccines pretty easily. Sometimes, it's
necessary to make our immune system work harder though, to produce even more
memory cells. Live vaccines are the real deal. An enemy that can punch back is a
bigger challenge than a dead one. But this also sounds like a sort-of horrible
idea. What if the germs win? To avoid that, we breed a sort-of weak cousin of
the real germ in the lab. Just powerful enough to annoy the immune system, and
create enough memory cells. Okay, so these are the basic principles of vaccine
use. They provoke a natural reaction in our bodies that makes us become immune against
very dangerous diseases. Some, like the flu virus, mutate so often that we need
a new vaccine every year, but most vaccines protect us for years, or even a
lifetime.
But, there's a catch. Like everything
in life, vaccines have another side: Side effects.
What are they, and what happens if your child develops one? The Risks of
Vaccines: It's complicated to directly compare the side effects of vaccines
with the effects of diseases. For example, hundreds of millions of people are vaccinated
against measles in the West, but there were only 83,000 cases in Europe in
2018. So, with numbers that different, even mild side effects can seem scary compared
to the bad effects of a disease that we don't see as much anymore. Before the
measles vaccine became available in 1963, virtually every single child on Earth
contracted measles at some point. An estimated 135 million cases in the 1950s every
single year. But are measles really that dangerous in the year 2019?
With our advanced healthcare and new technologies, are they worth the
risk of vaccine side effects? Let's do a thought experiment based on real
numbers. Imagine a developed country in a parallel world. It has good
healthcare but people stop vaccinating. In this scenario, let's say ten million
children caught measles. What happens? Nine million eight hundred thousand, or
98%, will get a high fever and a very unpleasant rash. Up to 800,000 of them,
or 8%, will suffer from dangerous diarrhea. 700,000, or 7%, will suffer from an
ear infection, which can lead to permanent hearing loss.600, 000 kids, or 6%,
will suffer from pneumonia: the most dangerous effect of measles. It, alone,
will kill 12,000 children. Up to 10,000 children, or 0.1%, will get
encephalitis. 2,500 kids, or 0.025%, will contract SSPE, a disease where the
measles virus lingers in their brain and kills them a few years later. Taken
together, around 2.5 million children will suffer from somewhat serious effects
of measles. And, about 20,000 children will be killed by measles. It doesn't
stop here though. The kids who beat measles are left with a severely damaged
immune system that needs a lot of time to regenerate. Time for other diseases
to do further damage. Aside from that, what's almost guarantee this that your
kids will have a really bad time for about two weeks. Okay, but what about
vaccines? It's only fair to look at these risks, too. So, let's repeat our
thought experiment. But, this time, we vaccinate ten million children with MMR.
What would theoretically happen here? After being vaccinated, of our 10 million
kids, around ten percent get a fever. 500,000, or 5%, will get a mild rash. Up
to 100, or 0.001%, might have a serious allergic reaction and will have to be
treated. Up to ten boys, or 0.0001%, might get inflammation of the genitalia. And
up to ten kids in total, or 0.0001%, might get the most serious side effect:
encephalitis. So, we vaccinated ten million kids. In total, around one hundred
and twenty had side effects that were somewhat serious. Thanks to good medical
treatment in developed regions, almost all of them will be fine.
What about autism?
The connection of autism and vaccines stems from one source that has
been disproven countless times. We'll link to further reading and videos in the
description. But, in 2019, it's fair to say that vaccines do not cause autism. All
right, but what about deaths? It's really hard to say if even a single one of our
10 million vaccinated kids would die. We really did look hard and talked to a
lot of different experts. If we ignore self-reporting, we could only come up
with a tiny handful of documented cases for all the hundreds of millions of
children who received the MMR vaccine since 1971. Measles are many, many
thousands of times more dangerous for your child than even the absolute worst case
of vaccine side effects. You have to search for lethal vaccine side effects
with a huge magnifying glass and, even then, it's very hard to find confirmed
cases. While deaths from measles are real and easy to find. In 2017 alone,
110,000 people died from measles worldwide. Statistically, today, 300 children
will die of measles.
What if your kid is actually allergic? What if none of the things we've
said applies to your specific situation? In this case, you need to become the greatest
vaccination promoter of all. Because if your children can't be vaccinated, only
the collective can protect them. This is called herd immunity, and it's the
only thing that can protect your unvaccinated child, which can be seen in the COVID-19 situation.
Herd immunity means that enough people are immune to a disease, that it
can't spread, and dies before it reaches its victims. But to accomplish this
for measles alone, 95% of the people around you need to be vaccinated.
Conclusion:
The problem with the debate about vaccines is that it's not fought on a
level playing field. While the pro-vaccine side argues with studies and
statistics, the arguments against them are usually a wild mixture of gut
feeling, anecdotes, and misinformation. And feelings are often immune to facts.
We'll not convince anybody by screaming at them. But we can't hide from the
reality of what anti-vaccine conspiracies do. They kill babies too young to be
vaccinated. They kill healthy children that are just unlucky. They bring
serious diseases back from the verge of extinction. And, the biggest side
effect of vaccines is fewer dead children. Vaccines are one of the most
powerful tools we have to eradicate the monsters that most of us have already
forgotten. Let's not bring the beasts back!

Good article. Didn't know the side effects of vaccines till today.
