Geneva-Sana
A panel of experts from the World Health Organization today recommended giving an additional dose of the coronavirus vaccine to people with moderate or severe immunodeficiency from all vaccines authorized by the organization.
AFP quoted experts as saying: “It is not a matter of recommending a third dose for the general public, which the organization continues to recommend freezing until the end of the year in order to secure doses for countries where the vaccination rate is still very weak.”
"The recommendation is to give immunocompromised people an extra dose to raise their immune response to the level of protection required to prevent severe forms of the disease requiring hospitalization or death," said Dr. Kate O'Brien, director of the World Health Organization's Department of Vaccination.
O'Brien added: The third dose of vaccines approved by the World Health Organization and requires two doses, except for the Johnson vaccine, which requires only one dose, which must be separated from the second dose by a difference of one to three months.
The same committee considered that a third dose for people over the age of 60 years is necessary for patients who received the two vaccines from the Chinese companies Sinovac and Sinopharm, and the third dose could be from another vaccine.
The World Health Organization has given licenses to the two vaccines powered by DNA technology sent from Moderna and Pfizer-Biontech, and the two Chinese vaccines, Sinopharma and Sinovac, and the Johnson & Johnson vaccine, as well as AstraZeneca.
