The federal government hopes to have results of the study of 30,000 people by the end of this year, which would represent an accelerated completion, given that the initial estimate of the vaccine was 18 months when it was announced in February.
The vaccine was administered in two doses, each one month apart. There were no serious side effects. However, more than half of the study participants complained of flu-like reactions to the vaccines, which were considered common and did not last long, according to Fox 5.
