WHO does not recommend 4th dose of Covid vaccines for general population

The World Health Organization (WHO) updated the recommendations for the use of vaccines against Covid19 this Thursday (18 August). According to experts from the Strategic Advisory Group of Experts on Immunization (SAGE), there is no need to give the fourth dose the second booster in the general population free of risk factors.

The indication for reinforcement is limited to groups at high risk of developing severe disease and dying from coronavirus infection, including the elderly, people with comorbidities, the immunocompromised, pregnant women and healthcare professionals.

WHO experts have constantly reviewed studies on vaccines and the immune responses of different population groups to immunizers. SAGE President Alejandro Cravioto said during a press conference that ensuring everyone gets the primary immunization (with the first two doses) remains a priority.

***Third dose against Covid

The Ministry of Health announced the reduction of the time interval for the application of the third dose of the vaccine against Covid19. The booster shot can now be taken four months after the second dose of Rafaela Felicciano/Metrópoles

Joachim Hombach, WHO Chief Health Advisor and SAGE Secretary, explained that the risk of the general population developing serious illness after the first booster dose is very low.

In addition, most people with the high prevalence of the virus have developed hybrid immunity, the combination of protection from vaccines and coronavirus infection, which Hombach says creates an increased defense.

“From this perspective, we see that the general population has good immunity to Covid19,” he said. “Of course we have to monitor,” he mused.
