COVID-19 Vaccine

During the winter of 2019, a new strain of Coronavirus emerged, and in the following months, it ravaged the world, causing a worldwide pandemic. The new strain was renamed SARS-CoV-2 but is commonly referred to as Covid-19 or simply “Coronavirus.” Over the year 2020, much of the world suffered from lockdowns. The entire world was under quarantine, and as a result, restrictions were placed down. Dine-in restaurants switched to take-out only and, later on, only outdoor seating. Masks were required in stores, which provoked riots and protests. Schools closed down, and online learning was the only way to learn until the 2020-2021 school year introduced hybrid learning. The new restrictions were necessary but caused devastating repercussions on businesses. Local restaurants closed down, and buffets shut their doors. Airline businesses plummeted, and hotels received fewer and fewer customers. As a result, workers in restaurants, airlines, and hotels were laid off.

However, the worst was yet to come, and that was the overwhelming amount of people hospitalized due to complications of the Covid. 2.5 million have been infected, and 27,500 have passed away from this disease. This is why scientists have been working day and night to come up with a vaccine. Finally, towards the end of 2020, Pfizer-Biotech developed the first Covid vaccine with 94% protection.

Most vaccines work by inserting a small, harmless amount of the selected virus into a person’s body via the bloodstream or nose. The body creates antibodies specific to that virus that target the actual virus when that person comes into contact with it.

As of January 2020, there are three different types of vaccines, and none of them are the traditional method of immunization.

The first vaccine was an mRNA vaccine. The human body has trillions of cells, and each of those cells has DNA in the center. A protein copies half of the DNA, and that is the RNA. The RNA travels outside of the cell’s center or nucleus, and another protein called a Ribosome connects to the RNA. Amino acids, which are like the building blocks of proteins, travel to the Ribosomes and connect to the RNA in a special pattern that creates proteins. The RNA creates a different pattern, which creates a different protein, and the proteins all have their individual purposes.

An mRNA vaccine inserts some RNA into the person’s body. The process of creating the protein then repeats. What is unique about this RNA is that this RNA is Coronavirus RNA. The body recognizes that this protein is alien, and it creates antibodies for the protein, thus creating antibodies for Covid.

A protein subunit vaccine is similar to the mRNA vaccine. However, instead of inserting RNA, it simply puts in the protein.

Finally, a vector virus vaccine is similar to the common vaccine with some slight differences. However, scientists take a weakened virus similar to Covid, but not the same virus, and put genetic makeup from Covid into the weakened virus or vector. The body then makes antibodies for Covid.

Most of the coronavirus vaccines require a second shot. An important thing to note is that none of these vaccines will cause coronavirus. Patients have reported feeling side effects, including mild fever, soreness, and headaches, especially after the second shot. However, while the side effects are uncomfortable, they are not harmful and have been reported to pass after a day or so.

It is essential to get the vaccine as soon as possible to build herd immunity. Herd immunity is the theory that if an unvaccinated or immunized person were to stand in a group of vaccinated people, the unprotected person would have a lower chance of getting the virus since the immunized people could not carry the disease.

Although the world has been turned upside down by the pandemic, scientists and doctors are working hard to turn it around. People must do their part and get vaccinated to turn life back to normal.
