The US’s top infectious disease specialist Dr Anthony Fauci has said that it is wrong for President Donald Trump to suggest that the US is 'rounding the corner' against Covid-19.

Fauci, who has been called out at political rallies by Donald Trump for his advice, predicted knowledge over a Covid-19 cure could arrive by the end of November or beginning of December, but warned there would not be enough doses to vaccinate everyone before 2021.

Appearing on the BBC’s Andrew Marr Show, Dr Fauci was asked if US President Donald Trump’s claims that a Covid-19 vaccine, while not a guarantee, will be coming by the end of the year were true.

Dr Fauci replied: “We will know whether a vaccine is safe and effective by the end of November, the beginning of December.

“The question is, once you have a safe and effective vaccine, or more than one, how can you get it to the people who need it as quickly as possible?

“The amount of doses that will be available in December will not certainly be enough to vaccinate everybody, you’ll have to wait several months into 2021.”

Dr Fauci added: “That could start by the end of this year, the beginning of January, February, March of next year.

“When you talk about vaccinating a substantial proportion of the population, so that you can have a significant impact on the dynamics of the outbreak, that very likely will not be in to the second or third quarter.”

His comments come amid reports plans are being made for frontline NHS staff to receive a Covid-19 vaccine within weeks.

Dr Fauci expressed concern that “anti-science” sentiment could have an effect on vaccine uptake.

He told the Andrew Marr Show: “One of the things I’m concerned about in the United States is that part of the anti science translates maybe into anti vaccine.”

He added: “It would really be a shame if we have a safe and effective vaccine, but a substantial proportion of the people do not want to take the vaccine because they don’t trust authority.

“That would really be unfortunate if that’s the case.”

Dr Fauci said a potential coronavirus vaccine, alongside public health measures, could help move the US towards “some form of normality” next year.

He said: “I think when we get a vaccine, and we start getting people vaccinated … over a period of several months into 2021, we will begin to approach some form of normality, depending upon how many people, what proportion of the people, take the vaccine.

“That should be combined with some degree of public health measures.

“I don’t think that a vaccine alone right off will get us back to normality.

“What I do foresee is that with a successful vaccine, and the continuation of some form of public health measures, as we go and progress through the months of 2021, getting towards the third and fourth quarter, we will see a considerable approach towards some form of normality.”
