Biden is cautious with his expectations of quickly escaping the pandemic

In the second task, cultivating too much optimism is just as risky as not creating many expectations for the public, experts say.

Every time America makes new progress in the vaccination campaign, President Joe Biden expresses optimism, but does not forget to warn about the challenges that lie ahead.

Joe Biden received the Covid-19 vaccine in Delaware last December.

His important announcement on March 2 that the US would have enough vaccine for all American adults by the end of May, two months earlier than previously estimated, came with a reminder that it may take time.

The Biden administration is pushing the vaccine program more urgently than ever.

Biden’s overall strategy so far has been to limit promises and not over-promote, accompanied by frequent reminders that Americans need to be vigilant as more nCoV variants emerge.

In his first days in office, Biden promised there would be enough vaccine for American adults by the end of the summer.

Although he always sees vaccination as the key to bringing life back to normal, Biden still refuses to announce a specific timetable for this goal.

`I was advised not to give a clear answer because we don’t know anything for sure,` the White House boss said on March 2 after announcing that the US was about to have enough Covid-19 vaccine.

`But again, I have to reiterate, it depends a lot on people continuing to understand that we can still suffer heavy losses,` Biden noted.

Unlike his predecessor Donald Trump, Biden always sets modest expectations and seeks to fulfill them.

But even after accelerating the pace of vaccine production, the US President continually refused to make predictions about when life would return to normal.

According to advisers, Biden’s hesitation, stemming from uncertainty about the possibility that vaccinated people can still be infected as well as concerns about nCoV variants, could significantly affect the effectiveness of vaccination.

Biden has always promoted the principle of `following the science` in his decisions on the pandemic, but some public health experts worry he is `following the science too much.`

According to them, as vaccines become more widespread and no longer scarce, the messaging needs to shift to how to open up safely, with less emphasis on dire warnings and more focus on the possibility of reopening.

Former director of the US Centers for Disease Control and Prevention (CDC) Tom Frieden said that the government `must send a message that is both optimistic and cautious`, highlighting advances in vaccines and the number of infections.

`On one hand, you want people to have reason to be hopeful that the pandemic is coming to an end, but on the other hand, you also need them not to let their guard down,` Frieden said.

The death rate of nCoV may be decreasing as some of the most vulnerable populations have been vaccinated, but even so, Covid-19 is still a `potential killer`.

Frieden said the next few weeks will be crucial.

`Managing expectations is the first step to help deal with crises effectively,` said Alex Conant, senior advisor to Republican senator Marco Rubio’s 2016 presidential campaign.

The optimistic announcement on February 3 about vaccine supply raised hopes among the American public, but it also put more pressure on the Biden administration to realize its goals.

`The responsibility is in the hands of the President,` Conant said.
