The Reality Check Episode 43

Real Vaccine Dangers + Cosmetics + Bilateral Symmetry

Bilateral Symmetry

Part 1:

Are vaccinations deadly? In this podcast, it's going to explore MMR, Polio, and DDT.

So, what is a vaccine? 

A vaccine is any preparation intended to produce immunity to a disease by stimulating the production of antibodies.

Vaccines are used for a lot of diseases, from smallpox to some sexual transmitted diseases.

But, people can die from vaccines. Do we just not get vaccinated? Would that be the best choice? 

Polio, mostly leads to muscular weakness. There are a few polio vaccinations, and one of them thought to make the polio worse. But those cases only happen one out of 750000. So, yes, people do get paralyzed when they get they get the vaccine to work with the polio disease. 

There is another kind of vaccination which also worsens polio if you are unlucky. Because polio can only be at one part of your body, once this kind of vaccine works with polio, polio spreads to the rest of the body. But, from 1997 to 2007, they gave 10 billion of these vaccines to around 2 billion people who had polio, and there were 9 cases. During those years, around 33000 kids got paralyzed by polio, but 6.5 million kids prevented polio because of the vaccines. 

How about MMR vaccination? Statistics say that no one died from MMR vaccination, but there have been around 1 in a million cases which the person have headaches frequently. 

Now we talk about DDT. This kind of disease affects the respiratory system. So, if you do get this disease, death is 1 in 20. 1 in 200 if taken care of. So, it's still better to take the vaccines. 

In conclusion, there's no such thing as a perfect vaccine, which protects everyone who receives it and entirely safe for everyone. 

Part 2:

Cosmetics, what do they actually do to us?

Sorry everyone, they mention a lot of medical things I can't spell, so if you like to know more, go to their website here: The Reality Check Episode 43

Science Myth of the Week: 

How much more evidence do we need for evolution?

There are certain things that still holds true, but there are "new" information about evolution, and not everything is exactly as Darwin said. If Darwin came to our society, he would look at our definition of evolution, he would see his fundamental ideas in them, but he would also see changes in them. Such as the genetic information we have now is beyond what anyone could have ever imagined back then. There is also the new taxonomy, even for many people that are still alive, that's a big change already. 

It's actually because we have new theories such as bilateral symmetry and radio symmetry, the way we classify the creatures changed. 

Bilateral symmetry is that your left right looks like your right side, if you are normal. 

This is because evolution can't be like just inventing anything from thin air. Evolution can only work with what they have already. They can only make tests and if they are better adapted in the environment, then they would survive.
