The agency has so far studied 116 of the reports, finding 20 percent of them to be serious and 80 percent non-serious.
The most frequent side effects reported included local reactions, such as pain and swelling at the injection site, a headache, an elevated body temperature, feeling weak and tired, shaking chills and nausea.
These are expected side effects and are similar to side effects of other vaccines. They are slight to moderate in intensity and they wear off spontaneously over a period of several days or after the use of symptomatic therapy such as cold compresses, fever-reducing medications and painkillers, HALMED said.
The agency said it had not received any reports of suspected side effects with a fatal outcome.
