Comparison of All Covid 19 Vaccines & How they work

These vaccines are all designed to teach the body’s immune system to safely recognize and block the virus that causes COVID-19. Although each COVID-19 vaccine is unique, all of them may help with herd immunity. (ये सभी टीके COVID-19 का वायरस को सुरक्षित रूप से पहचानने और ब्लॉक करने के लिए शरीर की प्रतिरक्षा प्रणाली को सिखाने के लिए डिज़ाइन किए गए हैं। हालांकि प्रत्येक COVID-19 वैक्सीन अद्वितीय है, ये सभी हर्ड इम्युनिटी में मदद कर सकते हैं।)

Several different types of concept are used for development of COVID-19 vaccines, including: (COVID-19 टीकों के विकास के लिए कई अलग-अलग प्रकार की अवधारणा का उपयोग किया जाता है, जिनमें शामिल हैं:)

  1. Inactivated or weakened virus vaccines, which use a form of the virus that has been inactivated or weakened so it doesn’t cause disease, but still generates an immune response. (निष्क्रिय या कमजोर वायरस के टीके, जो वायरस के एक ऐसे रूप का उपयोग करते हैं जो निष्क्रिय या कमजोर हो गया है, इसलिए यह बीमारी का कारण नहीं बनता है, लेकिन फिर भी एक प्रतिरक्षा प्रतिक्रिया उत्पन्न करता है।)
  2. Protein-based vaccines, which use harmless fragments of proteins or protein shells that mimic the COVID-19 virus to safely generate an immune response. (प्रोटीन-आधारित टीके, जो सुरक्षित रूप से प्रतिरक्षा प्रतिक्रिया उत्पन्न करने के लिए COVID-19 वायरस की नकल करने वाले प्रोटीन या प्रोटीन शेल के हानिरहित टुकड़ों का उपयोग करते हैं।)
  3. Viral vector vaccines, which use a safe virus that cannot cause disease but serves as a platform to produce coronavirus proteins to generate an immune response.(वायरल वेक्टर टीके, जो एक सुरक्षित वायरस का उपयोग करते हैं जो बीमारी का कारण नहीं बन सकता है, लेकिन एक प्रतिरक्षा प्रतिक्रिया उत्पन्न करने के लिए कोरोनावायरस प्रोटीन का उत्पादन करने के लिए एक मंच के रूप में कार्य करता है।)
  4. RNA and DNA vaccines, a cutting-edge approach that uses genetically engineered RNA or DNA to generate a protein that itself safely prompts an immune response.(वायरल वेक्टर टीके, जो एक सुरक्षित वायरस का उपयोग करते हैं जो बीमारी का कारण नहीं बन सकता है, लेकिन एक प्रतिरक्षा प्रतिक्रिया उत्पन्न करने के लिए कोरोनावायरस प्रोटीन का उत्पादन करने के लिए एक मंच के रूप में कार्य करता है।)

Currently, there are three main types of COVID-19 vaccines that are authorized and recommended or undergoing Phase 3 clinical trials.(वर्तमान में, तीन मुख्य प्रकार के COVID-19 टीके हैं जो अधिकृत और अनुशंसित हैं या चरण 3 नैदानिक ​​परीक्षणों से गुजर रहे हैं।)

Different type of Covid 19 Vaccines

S. No.Concept of vaccinesDescription
1.mRNA vaccinesFirst, mRNA is inside the immune cells (by administering in the body), the cells use them to make the protein piece. After the protein piece is made, Next, the cell displays the protein piece on its surface. Our immune systems recognize that the protein doesn’t belong to our body and begin building an immune response and making antibodies, like what happens in natural infection against COVID-19. At the end of the process, our bodies have learned how to protect against future infections.
2.Protein subunit/spike vaccinesThese include harmless pieces (proteins/spike) of the virus that causes COVID-19 instead of the entire germ. Once vaccinated, our bodies recognize that the protein should not be there and build T-lymphocytes and antibodies that will remember how to fight the virus that causes COVID-19 if we are infected in the future.
3.Vector vaccinesFirst, the vector (not the virus that causes COVID-19, but a different, harmless virus; Inside the shell of the Vactor virus, material from the virus causes COVID-19 to be inserted & this is called a “viral vector) will enter a cell in our body and then use the cell’s machinery to produce a harmless piece of the virus that causes COVID-19. This piece is known as a spike protein and it is only found on the surface of the virus that causes COVID-19. Next, the cell displays the spike protein on its surface, and our immune system recognizes it doesn’t belong there. This prompts our bodies to build T-lymphocytes and B-lymphocytes that will remember how to fight that virus if we are infected in the future.
