The lecturer Heba Daoud, from the College of Pharmacy, participated in the scientific symposium organized by the Network of Iraqi Scientists Abroad under the title (Modern Methods in Manufacturing Covid-19 Vaccines and Related Viruses) with the participation of researchers and specialists.

The symposium included the new methods and technologies that were used in the manufacture of Corona vaccines for the year 2021 and answered many frequently asked questions about the types of vaccines and whether they are safe or not?..

Where the researchers made it clear that it is safe and has undergone clinical trials to prove its effectiveness, the vaccine does not receive approval from the World Health Organization unless it meets these standards.

Among these three types of vaccines are known

The first is the Chinese vaccine, “Sinopharm”, which works by promoting the human immune system to make antibodies to the Corona virus, which bind to viral proteins such as the so-called spiny proteins that stud the surface of the virus.

The second and third are Pfizer Bionic and Moderna, working on messenger RNA technology, messenger RNA (mRNA for short).

And "mRNA" technology is based on programming human cells to produce copies of part of the virus, with the aim of stimulating the immune system to attack if the real virus enters the body.

The fourth is the AstraZeneca vaccine, where the vaccine forces the cells of the injected person to make exact copies of the “spike” protein of the real coronavirus, a glycoprotein, that protrudes from its surface. The protrusions on the surface of the cells of the same host are then recognized as a foreign gas by the immune system and attacked with antibodies.
