According to the study, all adverse events were mild and moderate and were more frequent after the first dose.

Between 13 and 30 July 2020, 827 participants were screened, of whom 375 were enrolled. Among the enrolled participants, 100 each were randomly assigned to the three vaccine groups, and 75 were randomly assigned to the control group.

"The most common solicited adverse events were injection site pain , headache , fatigue, fever, and nausea or vomiting," the journal said.

"All solicited adverse events were mild (43 [69%] of 62) or moderate (19 [31%]) and were more frequent after the first dose. One serious adverse event of viral pneumonitis was reported in the 6 μg with Algel group, unrelated to the vaccine," it said.
