Today we bring you the third episode in a new podcast series: COVID, Quickly. Every two weeks, Scientific American‘s senior health editors Tanya Lewis and Josh Fischman catch you up on the necessary developments in the pandemic: from vaccines to brand-new variations and whatever in between.
Tanya Lewis: Hi, and welcome to COVID, Quickly, a new Scientific American podcast series!
Josh Fischman: This is your fast-track upgrade on the COVID pandemic.
Lewis: I’m Tanya Lewis
Fischman: I’m Josh Fischman
Lewis: And we’re Scientific American‘s senior health editors. Today we’re going to speak about the barriers Black and Latino people face in getting COVID vaccines …
Fischman: How your immune system strikes back against new coronavirus versions …
Lewis: And what the heck is going on with the AstraZeneca vaccine.
More than 87 million individuals have gotten at least one dose.
Lewis: It holds true that states are opening up vaccination to more and more people, however Black and Latino individuals are getting vaccinated at lower rates than white and Asian people, in spite of getting sick and dying at greater numbers from COVID.
Fischman: You did some reporting on this with our colleague graphics editor Amanda Montañez. What states did you look at?
Black individuals in New York, Illinois and Florida are getting vaccinated at significantly lower levels.
Fischman: Did you get a sense of the factors for those patterns in the information?
Lewis: Many states have age minimums for vaccination, however Black individuals have a much shorter life span than white people, so they are at higher danger of passing away prior to they reach the age cutoff. Numerous Black and Latino homes are less likely to have high-speed Web and the time to invest online reservation vaccine consultations. They also are less most likely to own a vehicle to be able to drive to the vaccination websites. Language barriers and ID requirements likewise make it harder.
Lastly, vaccine hesitancy plays a role in some communities of color– for legitimate factors.
People are worried about all these brand-new coronavirus variants with anomalies, believing that they may evade the brand-new vaccines. You’ve discovered out that our bodies may have some countermeasures?
Fischman: Yes, we have actually all heard by now about the variations turning up that are more infectious than the original. Well, it ends up your virus-fighting cells might be evolving to keep up with them.
A number of groups of immunologists have actually been looking at people who were infected with the virus early in the pandemic. These individuals have antibodies against that early version of the virus. But– and this is truly interesting– the people also have reserve armies of immune cells. 6 months later these armies have actually mutated a little. They now churn out antibodies that are shaped a bit in a different way. Some appear to be a better suitable for the new variations. In test tubes, the antibodies neutralize the newer infection variations.
Basically, the immune system is trying to get ahead of the infection. That’s the description from Michel Nussenzweig, an immunologist at the Rockefeller University in New York, who did a few of this work. Monique Brouillette, among our authors, learned that he and other scientists are now attempting to determine if the body makes enough reserves to knock down a variant infection entirely. They do not understand. But it’s motivating to think our bodies aren’t just relaxing but actively trying to come up with brand-new antivirus weapons.
Why exists a lot controversy over the AstraZeneca vaccine? It’s been authorized in Europe however not yet in the U.S. I keep becoming aware of side effects and questions about how effective it is. What should we know?
Lewis: Last week there were concerns that the vaccine may have been linked to blood clots, but the European Medicines Agency (Europe’s FDA) concluded that it is safe and efficient, and the benefits surpass the risks.
And AstraZeneca has had some self-imposed problems.
On Wednesday AstraZeneca put out another declaration based on more recent results that revealed its vaccine is 76 percent effective and protects against severe disease. That is still excellent, so it seems to be more of a communication issue than a science one. Now Americans have access to 3 other vaccines, however AstraZeneca’s could still be hugely essential for the rest of the world.
Now you’re up to speed. Thanks for joining us.
