David Fidler has been thinking of a scenario that China will announce the successful first Phase three Covid-19 vaccine test, but not in the US.

"If China wins this race and takes advantage of it, while the US has nothing to do with it, what should we do? That's what worries me the most," said Fidler, global health specialist and

Fidler is not alone in worrying about what will happen in the next few months, as major powers are racing to get the first Covid-19 vaccine.

Among these vaccines were four candidates from China, three from the US Speed Campaign Project and one from Australia.

Fidler's fears were not unfounded.

If this scenario happens, many health and national security experts are concerned about a "nightmare" future, such as China refusing to provide vaccines to the US, the administration of President Donald Trump or candidate Joe Biden.

Larry Gostin, professor of global health law at Georgetown University, said that after China successfully developed a vaccine and provided it to the local population, Beijing "won't sell it to the highest bidder".

Fidler said that even if the Chinese vaccine is not bound, the US will hardly be able to obtain it, given the recent escalation of relations between the two countries.

Even this expert also worries that the vaccine race between the US and China could turn into a political race, competing for the influence of the two powers.

The Trump administration has called Operation Speedy one of the greatest humanitarian and scientific achievements in history.

All vaccines in clinical trials in the US and Europe use high-tech methods to activate the immune system against the spike protein of CoV, the primary tool for viruses to bind to and invade cells.

Kinch poses the question of what would happen if the approach aimed at prickly proteins didn't work.

Meanwhile, Kinch said China has a different approach.

"Without luck or due to the evolution of the virus, we can't make a strong and long-term response to the viral prickly protein, because other corona viruses also have this protein, the situation in the US could

Others are concerned about the way Operation Express selects potential vaccine candidates.

When asked about this approach, Francis Collins, director of the US National Institutes of Health, said Operation Acceleration takes risks within the safe range.

However, some experts believe that some Express Campaign candidates are being "overblown" for their likelihood of success.

"Why are there only 35? How about 504 others?"

Oxford then chose 10 people (not at random) for the second dose and the results were better.

"The road to a vaccine to commercial success often comes with tragedy. That is the price people have to pay for the lesson," he said.

On the other side of the hemisphere, President Xi Jinping could expect nothing more than to have the first safe and effective vaccine.

Experts say China can exploit more from that.

"What China is looking for in many places is just a door and they want to open that door," said Ned Price, who worked on the US National Security Council under President Barack Obama, adding that the department

Fidler argues that in the Covid-19 vaccine issue, some of the closest allies to the United States are even facing a difficult choice.

If the Xi administration can successfully develop a safe and effective vaccine and then distribute it worldwide, he could reap a lot of results in high-tech fields, such as 5G.

Fidler is also concerned about what will happen if the WHO finds the Chinese vaccine good, but the FDA dismisses it.

Although the FDA considers the Chinese vaccine to be safe, many people still doubt that China will distribute the vaccine to the US.

Gostin said that the US would do the same if the vaccine development succeeds before China.

In the event that China is willing to supply the US vaccine without any accompanying conditions, many will assume that Washington will not shake hands with Beijing.

Experts also said that even though Trump is a fickle man, it is very unlikely that he will "rotate 180 degrees" to see China as a savior and admit dependence on Beijing.

This makes Fidler and many other health experts fear another scenario occurs that the US will speed up the Speed Campaign and "burn the phase" of vaccine approval for political reasons.

This worry is completely grounded.

The FDA's move comes just before the Republican National Conference, and Trump accused the FDA of being slow to approve plasma treatments to damage his prospects of re-election.

"If the relationship between Washington and Beijing can't calm down on the medical front, we are in real trouble," Fidler warned.
