What are the composition and side effects of Covid-19 vaccines?

The coronavirus, which originated in Wuhan, China, in 2019, quickly spread worldwide and developed into a pandemic.

What are the composition and side effects of Covid-19 vaccines? -Accordingly, all personal habits of both consumers and service providers have changed radically. As Tourwix Travel we are trying to explain how the virus continues to affect individuals and sectors in relation to global travel activity. We have submitted many articles such as: What is Covid-19? What information is there about Covid-19 vaccines and the Covid-19 vaccine passport? Continuing from the previous articles, in this article we will explain the side effects of COVID-19 vaccines.

What are the content and mechanism of action of Covid-19 vaccines?

Covid-19 vaccines are considered to be the strongest asset to end the pandemic from the start. In late 2020, COVID-19 vaccine production began using multiple sources and different technologies, particularly in China, Germany and Russia. The most widely used vaccine, Pfizer BionTech, was approved for immediate use on December 11, 2020 and was quickly used in people aged 16 and over. By July 2021, a total of 4 billion vaccine doses had been administered worldwide.

Covid-19 vaccines can contain different antibiotics, active ingredients, proteins and live Covid-19 viruses, depending on the type. In general, there are two types of vaccine technologies that are used in response to the coronavirus. Vaccines made with mRna technology, like the Pfizer BionTech vaccine, teach the body how to fight the virus, while types of vaccines like Sinovac are vaccines that inject a live virus into the body free of harmful particles. All Covid-19 vaccines are manufactured in the shortest possible time with emergency approval and are treatments that, after years of research, achieve 100% effectiveness.

What are the side effects of Covid-19 vaccines?

Like all treatments, Covid-19 vaccines can have certain known or unusual side effects. The most common vaccine side effects reported by healthcare providers and vaccinated individuals, regardless of the type of vaccine:

• Severe pain, numbness and irritation in the arm that the vaccine was injected into and around the injection site. 84% of those vaccinated reported arm pain with injection.
   
• Superficial peeling of the skin due to dryness, redness and itching at the injection site. It is not known exactly whether this situation is caused by a vaccine or a previous allergic reaction of the person being vaccinated. These side effects were reported by 71% of people vaccinated.
   
• Fatigue, headaches, and muscle aches, which usually affect the entire body, are also side effects caused by the immune system fighting the virus that is given to the body in small amounts. Such side effects were observed in 63% of the vaccinated people.
   
• Problems with the digestive and excretory systems such as vomiting, diarrhea or intestinal discomfort are also common side effects of COVID-19 vaccines. Such complaints occur in around 40% of those vaccinated.

Various mild pain relievers may be used for minor side effects, but consult your doctor for different or very serious side effects. However, it is only natural for these side effects to occur within the first 2-3 days after the vaccine is given.

Vaccinations seem to be the most effective way to get rid of the Covid-19 pandemic, which is still going on around the world.
