According to Anvisa, the approval was based on a careful evaluation of the quality data of the studies that showed that the vaccine remained stable for a period of six months.

In Brazil, Janssen’s vaccine is authorized for emergency use since March 31 this year. The vaccine is the only one approved by Anvisa in a single dose and, when stored between temperatures of -25°C and -15°C, it has a shelf life of 24 months from the date of manufacture.
