The global health response
Amid persistent questions about the feasibility of corona vaccines and the extent of their effectiveness in preventing transmission of the infection, the World Health Organization clarified that the vaccines reduce the possibility of transmitting the virus to another person, noting that these interesting results have already begun to appear early.
And she went on to say that these results relate to only one or two studies, that is, they do not include all the vaccines that have been approved subsequently, which is why the organization continues to insist, despite the vaccinations, be concerned about continuing to wear protective masks and comply with preventive measures.
The head of the organization’s immunology department, Dr. Catherine O’Brien, confirmed in an interview with the magazine “Science in Five” published on the organization’s website that the majority of vaccination results to date indicate that they are truly effective against Covid-19 and that they provide effective protection against infection with severe cases in some way.
She also added that the first evidence obtained by the Department of Immunology of the World Organization shows that the vaccines are preventive against the appearance of symptoms, in addition to that there is evidence that they prevent infection in the upper respiratory tract, indicating that vaccination with the vaccine also reduces the duration of the infection, even if the person is infected.
Vaccinating people with Covid-19
As for what has been raised about a person with Covid-19 disease receiving a single dose, O’Brien responded, saying, “The World Health Organization continues to recommend that if a person has Covid-19 disease, he or she should undergo a full course of vaccines available and available to him or her, and so if it The available vaccine consists of two doses, then the person must receive both doses. ”
But the official went on to say that early evidence has already been followed that a single dose of the vaccine, especially in people who have already had the disease Covid-19, gives a very strong antibody response and enhances the immunity that has developed as a result of the disease they have contracted.
According to O’Brien, the reason why the World Health Organization recommends the need to go ahead and follow the full cycle of the two-dose vaccine is that, to begin with, there is still no evidence as to whether a single dose after a previous COVID-19 disease can be preventive, entirely or also from existing variables.
She also added that the second reason is that it is still not known exactly how long the protection is provided by one dose, so getting both doses can really give optimal protection against the virus and its mutated strains.
