COVID-19 vaccine: Side effects, distribution, and differences between coronavirus vaccines
-
0:03 - 0:06[How will COVID-19 vaccines
be prioritized?] -
0:06 - 0:10The people who are going to be
prioritized to receive the vaccines -
0:10 - 0:13are healthcare workers
who are on the front lines, -
0:13 - 0:17as well as anybody
who works in a hospital, -
0:17 - 0:20and then those who live
in skilled nursing facilities. -
0:20 - 0:25Skilled nursing facilities
account for about 6% of the population, -
0:25 - 0:27but almost 40% of the deaths due to COVID.
-
0:27 - 0:33So these are very high-risk individuals
for bad outcomes from COVID. -
0:33 - 0:38[Are there side effects
from a COVID-19 vaccine?] -
0:38 - 0:41It looks like it's the same
kind of side effects -
0:41 - 0:44that you would get from influenza
or a tetanus shot. -
0:44 - 0:48You get a sore arm for a day or two,
maybe a headache or fatigue, -
0:48 - 0:50and then that goes away.
-
0:50 - 0:54There's no way that you can get COVID
from the coronavirus vaccine. -
0:54 - 0:56So there's absolutely no way.
-
0:56 - 0:59It's just a small fragment of the RNA
-
0:59 - 1:03that encodes for a small portion
of the spike protein. -
1:03 - 1:06So it doesn't replicate,
it can't replicate, -
1:06 - 1:08and it can't cause COVID.
-
1:08 - 1:13[What does a vaccine mean
for masking and social distancing?] -
1:13 - 1:16We're going to have to be masking
and social distancing -
1:16 - 1:17for the foreseeable future.
-
1:17 - 1:20When we'll be able to stop masking
and social distancing -
1:20 - 1:23is when we achieve
some level of herd immunity -
1:23 - 1:25within our communities.
-
1:25 - 1:30That's going to take 60 to 70%
of the population to be immune. -
1:30 - 1:32Right now, through infection,
-
1:32 - 1:36if people are immune after infection,
which we're still not sure, -
1:36 - 1:41there's been less than 10% of people
in the US who have been infected. -
1:41 - 1:43And then when the vaccine comes out,
-
1:43 - 1:45it's going to come out
in limited quantities, -
1:45 - 1:49and so we're not going to be able
to vaccinate everybody all at once. -
1:49 - 1:54So we anticipate that we will be able
to achieve that 60 to 70% immunity -
1:54 - 1:57either through infection plus immunization
-
1:57 - 2:01in maybe the middle of 2021,
maybe the end of 2021. -
2:01 - 2:03We'll just have to see.
-
2:03 - 2:08[How do COVID-19 vaccines work?]
-
2:08 - 2:10So there's three main vaccines,
-
2:10 - 2:12and two of them
are messenger RNA vaccines, -
2:12 - 2:14mRNA,
-
2:14 - 2:17and those are the ones produced
by Pfizer as well as Moderna. -
2:17 - 2:22And so those vaccines, what they are,
is a fragment of the messenger RNA -
2:22 - 2:27that encodes for a certain portion
of the spike protein of the coronavirus. -
2:27 - 2:28That's the vaccine.
-
2:28 - 2:31So when that is given to us,
-
2:31 - 2:37then our own cells make that protein,
just a fragment of that protein, -
2:37 - 2:39and then we have an immune
response to that protein, -
2:39 - 2:43and that's how they work
to develop immunity. -
2:43 - 2:47The other vaccine is similar,
the Oxford-AstraZeneca vaccine. -
2:47 - 2:51It's a nonreplicating adenovirus vector
-
2:51 - 2:54that again has a fragment
of the spike protein, -
2:54 - 2:57and so then we get
an immune response to that.
