- The Trump administration is pushing hard
to have a COVID-19 vaccineby the end of the year.
But what are the risks of moving too fast?
Neurologist and best-sellingauthor Dr. David Perlmutter
(air whooshes)is here to talk about
vaccination research andwhere this virus came from.
Welcome back, Dr. Perlmutter.
- Thanks, glad to be back.
- Well, the presidentis saying we may have
a vaccine by the end of the year.
Is this advisable?
Are we rushing to get a vaccine?
- Well, we are definitelyrushing to get a vaccine,
and I don't think that'snecessarily the problem.
We want to expedite this, that's for sure.
But we do have to make sure that what
is ultimately produced andpurveyed upon the public
is both effective and safe.
Think back, in previoustimes, when we had swine flu,
and there was a vaccine created for that
and it was widelydistributed, and there was not
an insignificant number of people
who had some serious sideeffects, like Guillain-Barre
syndrome, which is a neurological issue.
So we have to make sure it's safe,
and we have to make sure that it's useful,
and I think that safety is first.
So everybody wants a vaccine tomorrow,
that's for sure, to endthis whole situation.
That's not in the cards.
Is it going to happen in six months?
That is a stretch.
I think we've been hearinga year to 18 months,
and I think reasonably,that's what we can expect,
but having said that, we were very buoyed
by the new report out ofOxford, England, last week
where a new technology is being utilized
to work on a previousplatform, a previous vaccine,
utilizing a differentRNA virus, modifying it
in such a way that it can then be
responsive or reactive against COVID-19.
And those researchers indicated that it
could be six months that they could have
enough of this to possibly go around.
So we just have to keepwatching the science,
and we all want thisto happen immediately,
but we have to think about safety.
- Break it down for us,what's the difference
that that platform makes,in terms of testing
and in terms of safetyand in terms of being able
to release it to a general population,
knowing that you alreadyknow the side effects?
- Well, they won't knowthe exact side effects
until, of course, it goes intosome form of clinical trial.
But the difference this time around,
in terms of what this oneparticular laboratory is doing,
is they are taking avaccine that's already been
created against adifferent respiratory virus
that happens to be also a RNA virus,
so it's quite similar, modifying it
in such a way that itwill then react against
the specific characteristicsof coronavirus,
and therefore, they believeit will be effective.
They've already triedthis on some primates,
on what are called macaque monkeys,
and found that it is incredibly effective.
When these macaque monkeys were exposed
to this coronavirus at very high levels,
which really is important,we can talk about that
in a moment, they had no reaction
in terms of developing any disease.
So getting that platformto be used in humans
is something that they've already done
in another context, witha previous iteration,
so we feel that this is going
to move along relatively quickly.
I want to just mentionthe idea of the dosage
that people are exposedto, and how that might
be relevant in terms of theseverity of the disease.
I just mentioned thatthese macaque monkeys
got a really whoppingdosage of coronavirus
and seemed to be protected.
This relates to humansbecause we're now seeing
an explanation as towhy healthcare providers
are getting this virus so aggressively.
Not only are they contracting it,
which you might expect, but they're having
a tough go with it, they'rehaving bad reactions to it,
and it might be because they receive
a much larger dosage on the front end
compared to somebody who, let's say,
gets exposed at a school or a restaurant
or some other type oflower-level exposure.
So it looks like the dosageof our exposure does matter,
in terms of how severeour experiences might be.
- All right, let's talkabout testing and tracing,
that seems to be one of thekeys to opening the economy.
Where do we stand with testing?
- Well, we've taken acouple of steps backwards
in terms of testing overthe past couple of days.
We've seen the FDA getinvolved and actually
really issue some warningsthat some of the testing
that is out there, andit's the Wild West in terms
of a lot of testing that's being created,
may not be really valid andmay create more harm than good.
We really need to makesure that people submit,
right now, there are several companies
that have 10 days to submit their results,
we really need to makesure that these tests
have very low levelsof both false positive
and false negative, so let me explain.
A false positive saysthat you've had the virus,
you have the antibodies,but it's erroneous.
And how can that be?
Well, we know that falsepositives can be induced
if you've had a previouscoronavirus infection.
We've most likely all been exposed
to a coronavirus, one form or another,
over the past many decades.
These have been around a very long time,
first identified inhumans back in the 1960s.
So previous exposure might trigger
some of these poor-quality tests to say
that you've now gotantibodies for this specific
COVID-19, and thatmight let a person think
that he or she is free to go out
and interact with others,maybe go back to work.
So we really have to ensurethat there's high standards
of quality in terms ofwhat these tests show.
Now, these tests are going to play
a pivotal role in giving us the ability
to allow businesses to resume.
We do feel that whenindividuals have a valid test
showing good levels ofone type of antibody,
we call them IgG, thatmost likely they carry
immunity and can no longer be infected.
There was a report out of South Korea
a couple of weeks agoindicating that even though
people are testing negative, about 2.1%
can have a recurrence of the disease.
Does that mean the virusis reactivated within them,
or does it mean they've caught it again,
they contracted again?
It looks like probably the explanation,
this was a big study, over 7,000 people,
it looks like the explanationis that the original
lab testing that showed thatthey had now tested negative,
didn't have the virus anymore, that
that might have been a bit erroneous,
so we need to continue to watch that.
But it doesn't mean thatbusinesses cannot resume
sooner than later with implementation
of appropriate socialdistancing, hand washing, gloves,
masks, and even Plexiglasisolation where appropriate,
allowing really the best of both worlds,
keeping people safe andallowing the economy,
then, to get back under way.
- Well, good advice, good analysis.
Thank you so much for being with us.
- Thank you, good to see you.
