  • Scientist behind BioNTech/Pfizer vaccine says it can end pandemic

The scientist behind the first Covid-19 vaccine to clear interim clinical trials says he is confident his product can “bash the virus over the head” and put an end to the pandemic that has held the world hostage in 2020.

The German company BioNTech and the US pharmaceutical giant Pfizer announced via a press release on Monday that their jointly developed vaccine candidate had outperformed expectations in the crucial phase 3 trials, proving 90% effective in stopping people from falling ill.

However, the lack of full data sets from the ongoing trials has left unanswered the question of whether the vaccine is also effective for those with asymptomatic infections.

In his first interview with a British newspaper, BioNTech’s chief executive, Uğur Şahin, told the Guardian he was optimistic. “If the question is whether we can stop this pandemic with this vaccine, then my answer is: yes, because I believe that even protection only from symptomatic infections will have a dramatic effect,” Şahin said in a Zoom call from his home in Mainz.

Until Monday’s trial results were revealed, the scientist said, he wasn’t sure whether his vaccine would trigger a strong enough reaction from the human immune system. “It was possible that the virus isn’t really targeted by the vaccine, finds its way into the cells and continues to make people ill. We now know that vaccines can beat this virus.”

While current trials of the BioNTech/Pfizer vaccine will not formally prove that it prevents transmission of the virus, as opposed to merely stopping infected people from falling ill, the 55-year-old said the high efficacy results have led him to assume it can.

BioNTech, a company founded in 2008 by the German scientists and married couple Şahin and Özlem Türeci, as well as the Austrian oncologist Christoph Huber, developed its vaccine with an experimental method known as mRNA.
