In an interview with BBC One’s Andrew Marr Show, Professor Sahin said the side effects of the vaccine were not enough to stop the study.
He said: “We did not see any other serious side effects that would cause the study to be paused or stopped.
“We have now had safety data for part of the subjects for more than two months, and we have continued to collect data for more than two years, to see not only the profile of the short and medium term side effects but also the long term. term side effect profile.
“But so far the security profile appears to be absolutely harmless.”
Recalling the moment he was informed of the effectiveness of their vaccine, Mr Sahin said it was “extremely relieving”.
He added: “As a scientist, of course you would expect a certain probability that the card could be positive based on the data we had so far, but there are still unknown factors.
“And there may be some scientific, biological or medical reason why the vaccine doesn’t work.
“We now know that our vaccine works, and most likely other vaccines will work as well.
