Immune System<\/strong><\/h2>\n\n\n\n

Blood contains red cells, which carry oxygen to organs, and white cells, which fight infection. Once vaccinated, body develops both T and B lymphocytes, the T-lymphocytes behave like memory cells and B-lymphocytes produce antibodies to attack the COVID-19 virus. White blood cells fight infection in different ways:<\/p>\n\n\n\n

  • Macrophages<\/strong> are white blood cells that swallow up viruses inflicted cells and form antigens. The body identifies antigens as dangerous and stimulates antibodies to destroy them.<\/li>
  • B-lymphocytes <\/strong>are different type of white blood cells which produce antibodies to attack the virus left behind by the macrophages.<\/li>
  • T-lymphocytes<\/strong> are another type of white blood cells that attack cells in the body that have already been infected. <\/li><\/ul>\n\n\n\n

    Three main types of Vaccines<\/strong><\/h2>\n\n\n\n
    • mRNA vaccines: <\/strong><\/li><\/ul>\n\n\n\n

      These vaccines contain material from the virus that causes COVID-19, once injected the human body makes harmless proteins. Human bodies recognize that the protein should not be there, build T-lymphocytes and B-lymphocytes to fight the virus that causes COVID-19 if we are infected in the future.<\/p>\n\n\n\n

      • Protein subunit vaccines <\/strong><\/li><\/ul>\n\n\n\n

        These vaccines contain harmless portions of the virus that cause COVID-19 instead of the entire germ. Once vaccinated, the immune system recognizes that the proteins don\u2019t belong in the body and begins making T-lymphocytes and antibodies, and provide with memory to fight the virus.<\/p>\n\n\n\n

        • Vector vaccines <\/strong><\/li><\/ul>\n\n\n\n

          These contain a dead version of live virus that has genetic material from the COVID-19 virus (Human Adeno viral vector). Once the viral vector is inside our cells, they prompt human bodies to build T-lymphocytes and B-lymphocytes that will remember how to fight the COVID-19 virus. <\/p>\n\n\n\n

          Which Vaccine is The Best for India?<\/strong><\/p>\n\n\n\n

          • Moderna<\/strong>: (most expensive and most efficient) 95% efficacy but stored at -20 degrees and 2-8 degrees for a month, genetic code technology is unique.<\/li>
          • Pfizer<\/strong>: (expensive) 94% efficacy but stored at -70 degrees, RNA based.<\/li>
          • Sputnik<\/strong> V: (Cheap) 95% efficacy but stored at 2-8 degrees This Russian vaccine is produced by Dr. Reddy\u2019s labs using viral vector technology.<\/li>
          • Oxford\/AstraZeneca<\/strong>: (Cheapest) 90% efficacy but stored at 2-8 degrees This Serum Institute of India, Pune is producing this vaccine using viral vector technology.<\/li><\/ul>\n\n\n\n

            Russian Sputnik<\/em><\/strong> V and <\/em>Oxford\/AstraZeneca<\/em><\/strong> are the two vaccines that may be used by India and the third world.<\/em><\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
