We have all seen the news lately – COVID, COVID, and more COVID! Should people get the vaccine? What about the booster shot? Are vaccines more harmful than COVID-19? Will my child have birth-defects? This blog post will (hopefully) answer most of your questions and clear up a very confusing topic of discussion!
First off, what are some potential effects of COVID-19? They include, but are certainly not limited to, shortness of breath, joint pain, chest pain, loss of taste, fever, organ damage, blood clots, blood vessel problems, memory loss, hearing loss tinnitus, anosmia, attention disorder, and the list goes on. So, our next question naturally is: what are the common effects of the COVID-19 Vaccine? On the arm that an individual receives the vaccine the symptoms include pain, redness, and swelling. Throughout the body, tiredness, a headache, muscle pain, chills, fever, and nausea can be experienced. To me, these effects seem much less severe than COVID-19’s!
Now that we have covered effects, you are probably wondering what exactly the COVID-19 Vaccine does – will it make it impossible for me to get COVID-19? Will I have superpowers? Well, you may not get superpowers, but your cells will certainly have a new weapon, which we will discuss in the next paragraph! The COVID-19 Vaccine reduces “the risk of COVID-19, including severe illness by 90 percent or more among people who are fully vaccinated,” reduces the overall spread of disease, and can “also provide protection against COVID-19 infections without symptoms” (asymptomatic cases) (Covid-19 Vaccines Work).
So, how does the vaccine work? Many people think that all vaccines send a small part of the disease into us so our cells learn how to fight it at a smaller scale. However, this is not the case with the COVID-19 vaccine! As we learned in biology class, COVID-19 Vaccines are mRNA vaccines which use mRNA (genetic material that tells our cells to produce proteins) wrapped in a layer of fat to attach to cells. This bubble of fat wrapped mRNA enters a dendritic cell through phagocytosis. Once inside of the cell, the fat falls off the mRNA and the strand is read by ribosomes (a protein maker) in the cytoplasm. A dendritic cell is a special part of the immune system because it is able to display epitopes on MHC proteins on its surface.
After being made by the ribosomes, pieces of the viral surface protein are displayed on the surface of the dendritic cell (specifically the MHC protein), and the cell travels to lymph nodes to show this surface protein. At the lymph nodes, it shows the epitope to other cells of the immune system including T-Helper Cells. The T-Helper Cells see what they’re dealing with and create an individualized response which they relay to T-Killer cells that attack and kill virus-infected cells. This individualized response is also stored in T-Memory cells so that if you do end up getting COVID-19, your body will already know how to fight it! The T-Helper Cells additionally gather B-Plasma cells to make antibodies that will keep COVID-19 from ever entering your cells. T-Helper Cells are amazing! As you can see, the vaccine never enters your nucleus, so it cannot effect your DNA! No birth-defects are possible!
You are now equipped with so much information and able to disregard many common misconceptions about the COVID-19 vaccine! Additionally, you can make an educated decision about whether or not you should get the vaccine. I think yes! If you have any questions, please feel free to comment them and I will answer. Thanks for reading!
