Only 3 cases to get a booster dose of the Corona vaccine… Health

Dr. Catherine O’Brien, Vaccines and Immunology Officer at the World Health Organization, has identified that there are actually three reasons for wanting to give an additional dose of the Covid-19 vaccine and its variants, according to Al Arabiya.

In the 53rd episode of the “Science in Five” program, presented by Vismita Gupta Smith, and broadcast by the World Health Organization on its official website and accounts on communication sites, Dr. O’Brien said that the first reason is if there is a group of people who did not respond adequately to the first two doses that were administered. I received them, as some information from the World Health Organization indicated that it may be necessary to receive a third dose for people who are immunocompromised, as long as the two doses of the vaccine did not achieve the same results seen in normal and healthy people.

She added that the second reason is that the immunity acquired by the person as a result of receiving the vaccination begins to diminish and deteriorate over time. But in fact, the evidence now shows that vaccines hold up very well in terms of protecting against severe illness, hospitalization or even death, indicating that global health experts do not see strong evidence that leads to the need to provide a dose A third for people who have already been vaccinated.

The third reason, says Dr. O’Brien, is that the performance of vaccines is under- or insufficient against some of the worrisome variables that have emerged recently, and she added that she reiterates that currently available vaccines are anti-variable and that the World Health Organization very carefully monitors the resilience of vaccines in Very well, vaccines work against exposure to a severe case of Covid, explaining that in general, vaccines work very well.

booster doses

In answering a question about whether there is a scenario in which certain groups of people might need a booster dose? So far, Dr. O’Brien said, there is some evidence that there is a small percentage of people who need the booster dose, namely people, who have severe immunodeficiencies who don’t seem to respond to the first two doses in the same way that people do. Those who do not suffer from an immunodeficiency state, and therefore need a third dose, explaining that it depends on the extent of their initial response to the two doses.

O’Brien explained that if they don’t respond adequately to the first two doses, they get vaccinated with a third dose, but aside from the protection that a booster gives people, there are some other considerations that scientists need to know.

Safety considerations first

There is certainly no conclusive evidence yet that a booster is needed among the majority of people who have already been vaccinated, O’Brien said. Safety considerations regarding the administration of a third dose need to be further investigated to ensure the safety of recipients of the booster dose before any such recommendation can be made.

She stressed that the current situation is that the vaccinations with which they have been vaccinated are still in good standing to protect against cases of severe disease, and prevent the need for hospital treatment or deaths, noting that this is the main goal of vaccines.

poorest countries

Dr. O’Brien noted that the focus must now be on providing poor countries with vaccines and support in order to provide protection for those people who have not been injected with vaccines at all, especially as this will reduce transmission of infection, reduce the possibility of the emergence of more variables, and give scientists time to see More evidence on whether or not boosters will eventually be necessary, stressing that no one will be safe until we all have a chance to be vaccinated and protected.
