The gold standard and definitive reference method for corona diagnosis is PCR tests, which due to the high sensitivity of this test requires a lot of precision and must be performed by a skilled technician in this process. As the pandemic prolonged and the incidence of the disease increased, the high cost of the test and, most importantly, the length of time it took to perform the test forced researchers to use simpler diagnostic methods that could be performed in a short time.
The close competition to create a vaccine for COVID-19 by the world’s leading biopharmaceutical companies has given people a fresh hope that the biggest pandemic of the century will be eventually eradicated. Meanwhile Pfizer and Moderna have recently announced their COVID-19 vaccines are more than 90% effective.

Introduction to the method of making Corona virus vaccine by two big companies “Oxford” and “Moderna”
Updates around the development of Covid-19 vaccines seems to be an almost daily occurrence at the moment, as the best medical and scientific minds around the world look to provide an end to the current coronavirus pandemic.
Vaccines from Moderna have produced high efficacy ratings in late trials, Janssen has launched a late stage clinical trial and now the University of Oxford / AstraZeneca jab has also returned encouraging results.
Throughout this pandemic, you’ve likely heard terms like Phase 1-2a trial and FDA approval, but what do these really mean—and at what point do they happen?
A vaccine would allow the body to safely develop an immune response to COVID-19 that could prevent or control infection.
it takes time to develop safe and effective vaccines – usually five to ten years on average. Despite promising reports about potential coronavirus vaccines being developed worldwide, it could take an estimated 12-18 months to develop one.
Vaccines contain the same germs that cause disease. (For example, measles vaccine contains measles virus, and Hib vaccine contains Hib bacteria.) But they have been either killed or weakened to the point that they don’t make you sick. Some vaccines contain only a part of the disease germ.
