WHO supports use of Janssen’s vaccine as a booster dose


The Strategic Consultative Group of Experts on Immunization (SAGE) of the World Health Organization (WHO) has approved the use of the vaccine against COVID-19 Janssen as a booster dose in people 18 years of age and older.

Specifically, WHO technicians recommend that the booster vaccine be administered between two and six months after the primary vaccination. SAGE advises WHO on global vaccination and immunization policies, and its recommendations provide guidance on the use of vaccines delivered through the COVAX mechanism.

The SAGE has recommended that the Janssen vaccine can be used for boosting in people who previously received this same dose as for those who received a different dose.

“The recommendation is further confirmation that the Janssen vaccine can help reduce the burden of the pandemic. Our vaccine continues to play a critical role in the global fight to end this pandemic, and we welcome this recommendation as we work with the global community to protect as many people as possible from COVID-19, ”commented the Global Director of Janssen Research and Development, Mathai Mammen.

SAGE’s tentative recommendation is based on efficacy, safety, and immunogenicity data from the company’s clinical trials and the Sisonke Phase 3b study sponsored by the South African Medical Devices Regulatory Authority.

When given as a booster dose, after primary vaccination with the Janssen vaccine, this dose provided increased protection against symptomatic infection and severe disease, and was generally well tolerated.
