A group of experts from the World Health Organization (WHO) recommended that a third booster dose be given to people over 60 years of age who have been vaccinated with Sinovac or Sinopharm.
According to the WHO, the recommendation is due to the fact that this age group has shown greater problems of response to the coronavirus after being vaccinated with both drugs.
According to experts, this recommendation could affect the vaccination programs of China, in addition to the countries of Latin America, Asia, Africa and Eastern Europe where these Chinese vaccines have been imported and administered.
The indication for this third dose should also apply to “moderately or severely immunosuppressed” people.
“The recommendation we give now is that people who are immunosuppressed receive an additional dose,” says a statement issued by the organization.
Dr. Kate O’Brien, director of the WHO Immunization service, said that the intention is to bring the immune response to the level of protection necessary to prevent the most serious forms of the disease or death.
Immunosuppressive people, whose body has a low defense system, were not part of the clinical trials with which the vaccination protocols were established.
Also, WHO experts recommended that the international community set a goal to vaccinate 70 percent of the world’s population against COVID-19 by mid-2022.
“It is a much higher percentage than we thought before, but given the development of the pandemic and the availability of new vaccines for younger age groups, it is a possible target,” said Alejandro Cravioto, president of the Strategic Advisory Group of Experts of the WHO (SAGE).
