It’s been a tough time we all suffered from; CoronaVirus or the Covid-19 had changed our lifestyles and made us stay at home.
Many damages had threatened our lives, jobs, and health, which led us to seek any possible help or any bright side.
Home nursing was also considered in a high rate to avoid hospital infection.
Since the virus outbreak late 2019, scientists and researchers were put at work trying to reach an effective vaccine hoping to go through this challenging time as soon as possible.
However, it’s not that easy to get a vaccine on such short notice. Usually, it could take years to produce a drug or vaccine after tons of researches, lab tests, and clinical tests, which let us imagine how huge the challenge was.
On the bright side, the world tends to reach an end to such a nightmare. After almost one year from the outbreak, several vaccines had been revealed and approved by the World Health Organization (WHO), giving the whole world a glance of hope.
Therefore, this article is dedicated to spreading out all the available CoronaVirus Vaccines, to know how it works, and if it has any dangerous side effects.
A year and a half later.
First, let’s get a quick update about the Covid-19 outbreak latest circumstances.
After almost a year and a half, the case count had exceeded 100M worldwide.
To get the full image, let’s talk in numbers for a while:
Mid-June 2021, cases reached 177,064,262.
While death cases are estimated to be 3,828,583.
Since it was claimed as a pandemic, so many genetic mutations appeared and caused new different symptoms and complications, such as the British, South African, Brazilian, and lately the Indian Mutation.
If you want to know more about the CoronaVirus you can check the following article.
This obviously reveals how a vaccine could be a rescue to limit this danger.
How does a CoronaVirus Vaccine work?
The vaccine idea was invented for the first time back in 1796 by Doctor Edward Jenner, who was a British doctor.
The whole idea rolls around, giving the body what motivates the creation of antibodies against a certain virus.
Every vaccine has one purpose and one purpose only: developing T-lymphocytes or T-cells that will memorize how to defeat a certain infection in the future.
Typically, it would take some time to get entire immune against a virus after vaccination, which means that a person is still subjected to infection for weeks after taking his dose.
Usually, a vaccine would contain the virus itself after being weakened, then injected into the body that starts to recognize it as a possible threat and begins to produce antibodies to defeat it.
Types of CoronaVirus Vaccines
While racing7 to reach an efficient vaccine, so many methods were used.
Currently, we have several kinds of vaccines based on different production methods, from which we can mention:
mRNA Vaccine:
This kind of vaccine acts as a delivery guy, who brings the virus RNA into our body cells, which lets them duplicate this protein and build an immune response.
Our body then starts to form T-cells and B-cells to keep this virus in memory and be ready to defeat it anytime in the future.
Viral Vector Vaccine:
Do you know Troy’s horse, in which Greek soldiers were waiting for the Trojans to let them in within their city walls so they can destroy it?
It could be compared.
This method uses a shell of another virus to envelope the main virus protein.
Once inside the body, the virus’s protein causing Covid-19 starts to penetrate body cells and let them duplicate it.
Unlike the horse of Troy, the viral vector vaccine doesn’t cause any harm to the person. On the contrary, it motivates the production of the T-cells and B-cells inside the body to build an immunity against the Coronavirus in the future.
Subunit Vaccine:
This vaccine depends on giving the body some particles of the virus itself, which are not harmful in any way, still enough to cause an immune response.
Letting the body producing T-cells and B-cells as usual.
Inactivated Virus Vaccine:
This is the classic way to produce a vaccine, and it had also been used through the Coronavirus.
The body is injected with the virus itself, not its protein, DNA, RNA, or even a particle.
But, the virus should firstly be killed or weakened before injecting to prevent the virus capacity and infection.
Which leads the body to deal with it as a threat and produce T-cells and B- cells without being a real danger.
Vaccines approved by the WHO.
So many vaccines had already been approved by the WHO to be used against the Coronavirus.
These vaccines were produced using several methods from the ones previously mentioned.
From which we can mention:
– Pfizer-BioNTech COVID-19 Vaccine and Moderna COVID-19 Vaccine as mRNA Vaccines.
– Oxford-AstraZeneca COVID-19 Vaccine, Johnson & Johnson COVID-19 Vaccine, and Sputnik V COVID-19 Vaccine as viral vector vaccines.
– Peptide Vaccine EpiVacCorona as a Subunit Vaccine.
– Coronavirus Vac as an Inactivated vaccine.
Moreover, so many other vaccines are still going through clinical tests and are expected to be approved shortly.
CoronaVirus Vaccines Side Effects
So many doubts are rolling around these vaccines, as they were produced in such a short period.
However, there’s no registered danger or incident that was directly linked to the CoronaVirus Vaccine.
Knowing that it still has some side effects, which are totally normal and do not represent any health threat.
After having your dose, and while your body is producing antibodies, you can get a fever, feeling ill, and feeling some pain on the spot where it had been injected.
Symptoms and severity vary from one to one according to age, immune system, chronic diseases (high blood pressure, low blood pressure, diabetes,…), and many other factors.
