Starting on January 11th?There are three big questions about the development of a covid-19 vaccine in the United States

At present, although the global covid-19 epidemic has been gradually brought under control, it still has a certain impact on the economic operation and social stability of all countries. It is urgent to develop an effective vaccine as soon as possible, and many countries are working intensively on vaccine research and development.In recent days, however, some of the information and practices in the U.S. have been questioned.

Question 1: the United States has long known about novel coronavirus?

US President Donald trump said at a press conference in the White House rose garden on Tuesday that the us had started work on a vaccine on January 11 and hopes to have it available by the end of the year.”The government and a lot of private companies are doing research and development,” trump said. “we’re already working 24 hours a day, so we have time. We hope to have a vaccine by the end of the year or later.”

A short message, a huge amount of information.

On January 11th the United States began developing a vaccine.On January 12, China Shared information on the novel coronavirus genome sequence with the world health organization.On January 21, the CDC confirmed the first confirmed case of covid-19 in the United States.

Just after China discovered the genome sequence of the virus, americans started vaccine research.

Trump said the United States had been working ona vaccine as early as mid-january, proving that the country had mastered every aspect of the novel coronavirus.There’s a lot of information behind this point in time.

Why didn’t the federal government take action early when the vaccine was already in the works?This practice has aroused many netizens to question.

“Think about it, these scientists have been working on a vaccine since January 11th, remember that date!” wrote Internet user Pamela k. melenchen.Left left left

Scientist Charlie Whittaker said: “the President said it was really interesting that people have been working on a vaccine since January 11th, as if someone knew what we were dealing with.”Left left left

Dgmtick1 said: “it’s too bad that politicians waste the whole of December, January, February and most of march playing their political games and calling novel coronavirus a hoax.This is manslaughter by trump and his politicians.”Left left left

“In fact, the bio-pharmaceutical company Moderna has the ability to develop novel coronavirus vaccine for the United States because it started on ‘January 11’ and the Chinese government Shared the gene sequence in time,” netizen Y said.This shows that there is no delay in information sharing, no more blaming China for not sharing information in a timely manner, and now a global effort is needed to save lives!”Left left left

Question 2: a vaccine by the end of the year?American health experts say it is unrealistic

During the same day’s press conference, trump announced that he was launching a vaccine development program called operation twist. He also named two leaders of the initiative, monsif sloe, a former senior executive in glaxosmithkline’s vaccine division, and gustav perner, a four-star U.S. army general.The plan is to combine pharmaceutical companies, government agencies and the military to reduce the time it takes to develop a vaccine to eight months, and hopes to produce as many as 300 million doses by January.

But us health experts have warned that Mr Trump’s timetable for a vaccine by the end of the year is unrealistic.

Paul Offit, director of the center for vaccine education at children’s hospital of Philadelphia, said the government’s timetable was premature.Scientists still don’t know which of several vaccines will work, or what level of immune response signals indicate that a person has begun to be immune to the virus.

Peter Jay Hotez, director of the national school of tropical medicine at baylor college of medicine in the United States, said some large trials could begin this summer, with a record timetable of around the second half of next year for a safe and effective vaccine to be available.

Making a vaccine is a time-consuming process, and in addition to the scientific difficulties, testing for safety and efficacy takes a long time, according to the Washington post.Unlike cancer treatments or the development of drugs to treat disease, vaccines are offered to healthy people and require minimal side effects and risks.

U.S. epidemiologist David fauci previously estimated that vaccine development would take 12 to 18 months.

Question 3: new uncertainty over vaccine development

The guardian published an article on May 12 titled “the race for vaccine development: how trump’s America first policy is slowing international r&d cooperation.”The article points out that, unlike the fight against HIV/AIDS and ebola in the past, the United States is resisting calls for international cooperation in its response to covid-19.

The White House says it has no plans to attend the upcoming global vaccine summit in early June, according to the article.Stephen Morrison, director of the center for global health research and policy at the center for strategic and international studies (CSIS), a prominent us think tank, said, “the U.S. seems to be sticking to the principle of ‘America first’ by not attending and not participating in recent meetings.”

Mr Morrison said the risk posed by this style of conduct was that the us departure would disintegrate the international effort, creating new tensions, uncertainty and insecurity.Disrupting the entire system of vaccine production could slow development and make it more difficult to achieve universally effective solutions, Morrison said.
