protocols enhances attendance education
The health expert, family and community medicine consultant, Professor Tawfiq Ahmed Khoja, called on school students who were included in the decision to return after receiving the two doses, the necessity of positive interaction with the preventive protocols for the return of education in presence, which was announced by the Ministry of Education, indicating that students and educational staff must continue to apply special precautionary measures. Corona virus, as vaccination with two doses does not justify not wearing a mask or not applying physical distancing.
He advised the educational staff who completed the first dose to take care to take the second dose on time before the start of the school year, so that they can continue education on time, stressing that the second dose has a major role in enhancing immunity and protecting against mutants that have begun to threaten the world.
Regarding the mutation of the Corona virus, Professor Khoja explained
All viruses mutate naturally over time, and the Corona virus has mutated as well. Since the virus was first identified in early 2020, thousands of mutations have appeared on it, and mutated viruses are called strains, and most changes have little or no effect on the characteristics of the virus, according to the World Health Organization. global), many of which disappear over time, but from time to time the virus continues by mutating in a way that helps it survive and spread, and this is what is happening now with the Corona virus with the emergence of several strains, namely alpha (first found in Britain), and beta (southern Africa), Gamma (Brazil) and Delta (India), all classified as strains of concern by the World Health Organization because they pose a public health risk by making the virus more contagious, or causing more severe disease, so everyone is advised to take The two doses of immunization.
Regarding immunization with two different doses, Professor Khoja concluded
Studies have revealed that mixing vaccines provokes strong immune responses, and that it may even be stronger than taking two doses of the same vaccine, in addition to its ability to confront mutations in the virus, and most studies that were conducted to prove effectiveness, including a study conducted at Oxford University, consider that The two-dose course of the Pfizer vaccine produced the highest level of antibodies, which directly fight the virus. However, people who underwent a first dose of the “AstraZeneca” vaccine followed by a second dose of the “Pfizer” vaccine had the strongest level of cells capable of producing antibodies that help destroy cells infected with the virus, and thus it can be confirmed and said that vaccination with two different doses contributes It also boosts the immune system.
