According to WHO, more than 100 novel coronavirus vaccines are currently in development, led by the university of Oxford, Pfizer, Moderna Therapeutics, Inovio Pharmaceuticals and China’s CanSino Biologics.
These organizations or companies use different vaccine development techniques, but it is not known which one will be the most effective and the first to appear.
The us government has said the novel coronavirus vaccine will be available in January 2021, and trump has said in public that the vaccine will be vaccinated by the end of the year.
However, scientists and vaccine workers outside the government, while optimistic about the date, say it is a very challenging thing to do.
One expert, speaking on condition of anonymity, said a vaccine could be ready within 12 months, meaning all the steps would be perfect and “break a certain ‘scientific rule'”.
“We also need to make sure that the vaccine is safe and effective,” said Dr. Anthony fauci, a leading infectious disease expert.
He also estimates it will take 12 to 18 months for a coronavirus vaccine to be available.
Remember that the fastest vaccine ever, the mumps vaccine, took four years.
But the number of infections and deaths has risen (by 28 May, more than 5.8 million cases had been confirmed worldwide, with nearly 360,000 deaths;
More than 1.74 million cases have been confirmed in the United States, with more than 100,000 deaths.
Pharmaceutical companies are also ramping up production amid uncertainty about which vaccines will work.
Paul Offit, the co-inventor of a rotavirus vaccine, says it is not impossible.
Paul Goepfert, a vaccine expert at the university of Alabama, says if every step is perfect, it’s not impossible.
Experts say vaccination trials need to be conducted in hard-hit areas to determine the effectiveness of the vaccine before it can be administered.
Rinke Bos, chief scientist and immunologist at Johnson & Johnson, which is developing one of the new coronavirus vaccines, said it is difficult to set a time frame.
It is important to note that due to the severity of this outbreak, many vaccines have been developed out of the normal process, for example by skipping animal trials and entering humans.
