The preprint notes that during the trial, the vaccine was most likely being tested against beta or delta – two variants of the coronavirus that other vaccines have found harder to control.
Before this, a phase 1 study of giving Soberana Plus to people who had already had COVID was published in September. This was testing the effects of Soberana Plus as a booster to natural rather than vaccine-induced immunity. It showed no safety issues and stimulated a good immune response when used in this way – though the study was small, involving just 30 participants.
For Abdala, the only phase 3 trial data available was issued by Cuban press releases in June and July 2021. The three-dose schedule is also reportedly 92% protective against symptomatic COVID as well as allegedly fully protective against severe disease and death.
