Yes, but there are side-effects.

There were no dangerous side-effects from taking the vaccine, however, 70% of people on the trial developed either fever or headache.

The researchers say this could be managed with paracetamol.

Unrelated PS-2: I didn't notice that someone else here has already quoted the above part. Sorry for the duplication.
