Vaccines: Myths versus Facts

“The government rushed the trials; the lawyers indemnified the drug companies. Maybe it causes autism, narcolepsy, or cancer 10 years from now. WHO KNOWS?” (Alan, Contagion 2011).

Haven’t watched this blockbuster already? Wait till you finish this blog and WATCH IT ASAP!

I bet you’ll be surprised how accurately a movie from 2011 portrays the world in a global pandemic. Though the plot revolves around tackling the virus and finding a cure amidst a global health crisis, Contagion also raises some pretty interesting questions. Alan, the main antagonist argues how the big Pharma is deeply anchored to make the best profit out of every opportunity. That they don’t care what side effects the vaccine may have and that the dollars speak more than the health of the general public. But let’s not further spoil the movie and understand what actually is a vaccine.


So, what is a vaccine?

According to the CDC, Centre for Disease Control and Prevention, vaccines are a simple, safe, and effective method to train the body’s immune system into creating antibodies for harmful diseases without coming into contact with them. In simple words, vaccines use our body’s natural defenses to build resistance against certain infections and make our immune response stronger. Usually, this is achieved by using a killed or weakened strain of the specific disease.

But wait…If they’re using the same disease to create vaccines for it, what if it actually causes the disease? What if it causes cancer or narcolepsy or autism just like Alan said? WHAT IF THEY’RE PLANTING COMPUTER CHIPS IN THE NAME OF VACCINES??? NO!!

Sometimes these rumors can be overwhelming and vaccination may seem dangerous, but there can be no better way than to address these myths head-on and understand what the actual facts are. Let’s begin, shall we?


Myth: Vaccines cause autism

Ahh…What a classic to begin with. Let’s settle this once and for all. Claims of vaccines causing autism stem from a single study published in 1998 which raised concerns about possible connections between the measles-mumps-rubella (MMR) vaccine and autism. Later, however, the study was found to be seriously flawed and fraudulent such that the paper was retracted by the journal that published it and the author lost their medical license. Unfortunately, its publication has continued to fuel the agenda of the anti-vaxxers over the years and has lowered immunization rates in many countries. Nevertheless, there is no evidence of any link between vaccination and autism or autistic disorders to date which has been demonstrated in many studies, across very large populations.

Myth: Covid-19 vaccines cause infertility

No, they do not. But Covid might. In December 2020, a German epidemiologist raised concerns stating the Covid-19 vaccine might cause rejection of a protein connected to the placenta in women, therefore making women infertile. This was quickly picked up by the anti-vaccination blogs, websites, etc., and became the forefront of the battle against Covid vaccination. However, clinical trials and preliminary research have shown that Covid-19 vaccines appear to have no impact on women’s fertility. However, a recent review paper published in the journal Reproductive Biology shows that Covid-19 can cause decreased sperm count, testicular inflammation, sperm duct inflammation, and testicular pain in men of reproductive age. These effects are enough to lead scientists to hypothesize that Covid may cause fertility issues in men, warranting further research in this area.

Myth: Vaccines have too many severe side-effects

Sorry, you’re completely wrong about this, Alan. The side effects from most vaccines are mild. These include swelling or soreness at the injection site, a mild fever, chills, and general malaise. These reactions usually go away within hours but in rare cases could last for a day or two. It is estimated that out of a million vaccinations, one or two people have a serious allergic reaction. However, catching the disease can prove to be much more problematic compared to the side effects of its vaccine as explained by Kurzgesagt in their video on ‘The Side Effects of Vaccines’.


Myth: Vaccines can actually cause disease.

Nope. Vaccines can induce modest symptoms similar to the disease they are designed to protect against. A widespread misperception is that these symptoms indicate illness. In fact, in the small percentage of cases (less than one in one million) where symptoms do arise, they are caused by the body's immune response to the vaccine rather than the disease itself. This is because some vaccines contain weakened or dead cousins of the real virus which helps the immune system create memory cells.

Myth: Vaccines contain dangerous chemicals

Once again, NO!! Though there are some unsettling-sounding components in vaccines, such as formaldehyde, it is vital to highlight that they are present in very little and harmless concentrations. In fact, the quantity of formaldehyde in vaccinations is less than that found in the body. Mercury in vaccinations is also a concern for some parents. Thimerosal, a mercury-containing compound, was taken out of childhood immunizations in 2001.


Right…What now then?

It’s been over 200 years since Edward Jenner founded vaccination by inoculating a 13-year-old boy with cowpox to demonstrate immunity to smallpox. Yet, vaccination is still considered ‘unnatural’ in many societies and people like Alan are always there, capitalizing on every opportunity to spread misinformation and their agenda against vaccines. Therefore, it’s in our greater good to not just take vaccine shots for ourselves but also promote it to the fullest.

Genetically Modified Animals: Jurassic World and Real World

Image
By: Insha Mushtaq Creating genetically modified animals have been a scientist’s goal since genetic engineering had shown some progress in the realm of treating or modifying tissue with the help of gene cloning, gene therapy, or gene editing. Moreover, with the rapid advancement and adaptation of science, genetic engineering has prospered a great amount and has been constantly showing some promising outcomes in genetically improving species for the better. However, humans get crazy when they think about genetically modified animals, especially in movies where their practical implications and limitations can be dodged. Sci-fi movies like Jurassic World, which is built around the notion of genetically modified animals, the directors tend to lean more towards the fiction side and sadly undermine the practical aspect of it. And perhaps that is the reason why sometimes the most basic science is ignored when making a science fiction movie. Simpler visual of how scientists take out genomes fro...

By Eraj Rizwan Hollywood Sci-Fi vs. Reality: Could “ I am Legend ” Actually Happen? Disclaimer- This blog contains spoilers (obviously) Imagine a world without crowds, no queues, no traffic, no hustle and bustle- basically no other humans except you and your dog (and occasional a herd of deer, and lions). It is not as great as it sounds, ask Dr. Robert Neville about that ! A lightning-paced ride through a post-apocalyptic world where all the human beings except Robert Neville (Will Smith), an ex-military virologist, have been killed by a virus called Krippin virus or transformed into angry cannibalistic species called Darkseekers, who emerge at night, hunt anything that moves, and cannot be relied upon for civilized conversation. Between a highly regimented schedule hunting deer with his dog, Sam, and driving to the rental store and chatting with mannequins, Neville tries to find a way to reverse the virus using his own immune blood. He has not had much luck in three long, lonely...

Can Creatures Morph into a Different Sex? Splice vs Nature

Image
 by Wajiha Paracha Can you imagine a creature switching from one gender to another just when they feel like it? Well, that's what happened in splice with Dren; a creature made from animal hybrids and human DNA. Image: dren (creature) infant of Clive and Elsa (genetic engineers) More about the film Splice: Splice was released in 2019 and portrayed the obstacles and pitfalls that genetic engineers: Elsa and Clive had to go through by secretly making a human-animal hybrid, Dren.  Both are partners in the laboratory of a genetic science corporation. Initially, they were attempting to create an animal hybrid gene which turned out to be successful.  Although the corporation had got what they needed, Clive and Elsa proposed how they can take the level up and add human DNA. The proposal was rejected but Elsa was stubborn to find out what would happen next, so she secretly added human DNA into the lab work.  After a few days Dren came into existence; a half-human, half-...
