CDC director says coronavirus vaccine won’t be
widely available until late 2021
The estimation runs counter to Donald Trump’s recent
messaging that a vaccine will be available ‘in a matter of weeks’

The
director of the Centers for Disease Control and Prevention (CDC) has told a
Senate panel that he thinks it will take one year before a coronavirus vaccine
will be “generally available to the American public”.
That
estimation contrasts with recent bullish messaging by Donald Trump, who on
Tuesday repeated his assertion that “we’re going to have a vaccine in a matter
of weeks” even though a successful vaccine has yet to be unveiled from ongoing
US trials, and attacked the CDC director on Wednesday as “confused” about the
timeline.
Trump did
not specify whether he was talking about a “generally available” vaccine or a
limited number of doses, but he has suggested during his re-election campaign
that a vaccine solution to the pandemic crisis in the United States was
imminent.
Robert
Redfield of the CDC testified before the Senate on Wednesday as his agency
issued a paper with impressionistic advice for state and local jurisdictions on
how to prepare to distribute a coronavirus vaccine – when and if a vaccine is
approved.
Redfield
said he expected vaccinations to begin in November or December, but in limited
quantities prioritized for healthcare personnel, at-risk populations and other
vulnerable groups.
However at
a press conference Wednesday afternoon, Trump said Redfield was “confused” when
he said that a vaccine will only be available for first responders if it is developed
by November or December.
“I think he
made a mistake with that statement,” Trump said. “When he said it, I believe he
was confused. I’m just telling you we’re ready to go.”
Redfield
also told the Senate he believed face masks were “the most important, powerful
public health tool we have” to combat coronavirus, including a potential
vaccine. “This face mask is more guaranteed to protect me against Covid than
when I take a Covid vaccine,” he said, explaining that a vaccine would probably
not ensure immunity in all cases.

On this
point, Trump also contradicted him, saying that Redfield “made a mistake”.
“Masks have
problems too. ... A lot of people did not like the concept of mask initially,
Dr Fauci didn’t like it initially,” Trump said. He did not mention that Fauci
has since clarified that he advised against masks early in the pandemic out of
fear that the guidance would create a panic-induced shortage on personal
protective equipment for essential workers.
Trump has
repeatedly inflamed doubts about the value of masks, saying at at a town hall
event on Tuesday, when asked why he did not wear a mask, that “a lot of people
think the masks are not good” and, when asked for an example, named “waiters”,
describing a scene where a mask was used incorrectly.
While
multiple vaccine candidates are in the last stage of clinical trials,
pharmaceutical companies and health officials have warned in recent weeks that
they would not risk the public health by rushing the process. Winning
regulatory approval for a vaccine typically takes years.
Redfield
testified before a Senate subcommittee overseeing spending for health and human
services.
“If you’re
asking me when is it going to be generally available to the American public so
we can begin to take advantage of vaccine to get back to our regular life, I
think we’re probably looking at third – late second quarter, third quarter
2021,” Redfield said.
The paper
issued by the CDC on Wednesday advised localities to set up teams to prepare to
distribute vaccine doses, but the paper advises that the details were still
fuzzy.
“It is not
yet known which vaccines will be available, in what volumes, at what time, with
what efficacy, and with what storage and handling requirements,” the guidance
said.
“A key
point to consider is that vaccine supply will be limited at the beginning of
the program, so the allocation of doses must focus on vaccination providers and
settings for vaccination of limited critical populations as well as outreach to
these populations. The vaccine supply is projected to increase quickly over the
proceeding months.”
In a list
of challenges facing vaccine distribution, the paper calls on local
jurisdictions to “ensure [that] vaccination locations selected can reach
populations, manage cold chain requirements, and meet reporting requirements
for vaccine supply and uptake”. “Cold chain requirements” refers to the need
for certain vaccine doses to be kept in super-chilled environments.
Apart from
the general advice from CDC, the federal government did not appear to be making
extensive preparations to build a national vaccine distribution effort.
Officials
from the Department of Health and Human Services and the Department of Defense
on Wednesday held a call with reporters and then released documents on the
distribution plans that it is sending to the states and local public health
officials.
The CDC
guidance advised localities to consider piggybacking the coronavirus vaccine on
“routine immunization and pandemic influenza program activities”.
The uptake
rate for the annual influenza vaccine is about 50%, meaning that agencies could
face difficulties persuading a sufficient share of the public to vaccinate to
deliver immunity protection.
It is not
known what vaccine candidates the government may be preparing to authorize, or
what level of immunity those candidates might confer for how long. Multiple
doses of a vaccine could be required, and multiple vaccines of varying efficacy
may be released.
“It is
imperative that state and local authorities combine and coordinate efforts,”
the CDC advised.
At a White
House briefing, the press secretary, Kayleigh McEnany, went much further than
Redfield and said the White House believed a vaccine “will be widely available
by the end of the year”.
When
queried she said the government expected 100m doses to be “in production by the
end of the year”, without further clarifying.
