A: In the words of virologist Dr. Angela Rasmussen, “people infected with Delta are shedding a s**t-ton more virus than with earlier variants.” A newly released study has provided some clues to Delta’s transmissibility tricks by testing viral loads in quarantined close contacts of confirmed cases. Contacts were tested daily by PCR, and the course …
A. No. COVID-19 vaccines do not affect existing immune cells or antibodies that you have made against other viruses. Nor will it prevent you from making an immune response to another virus when you encounter it. 👉 TL;DR: Our immune system is designed for IMMENSE flexibility to be able to respond to thousands of pathogens …
Let’s face it: B.1.1.7 and B.1.351 don’t easily roll off the tongue. While naming variants after the place they were first identified is common in virology, during the pandemic there has been concern about stigmatizing particular countries when using these names in public discussions. The WHO has adopted a new Greek alphabet naming system to …
A: Gene therapies treat diseases using genetic tools. They usually work by making lasting changes to your DNA — the genetic “cookbook” that provides instructions to make you. Vaccines, by contrast, deliver a short-lived signal (e.g. a burst of protein), then disappear. Vaccines and gene therapies both use customized genetic tools to achieve their goals. …
A: The origin of the COVID-19 pandemic is still being unraveled. The leading theory is that SARS-CoV-2 jumped naturally from bats to humans (possibly through an intermediate species), as other viruses have done for ages. The lab-leak theory – an accidental spill from a research lab – is the underdog. It’s far less likely but …
A: It’s possible. #VaxUpToGetItUp TL;DR: Due to its impact on inflammation and the vascular system, it is biologically plausible that COVID-19 contributes to erectile dysfunction. But as with much COVID-19 research more, ahem, hard data is needed. COVID-19 infection HAS been associated with a reduction in sperm counts in early research. A recent study found …
R: No. No hay evidencia de que las personas vacunadas contra COVID-19 tengan una respuesta hiperinmune si son expuestas al virus. En resumen: La exposición al SARS-CoV-2 después de haber recibido la vacuna contra COVID-19 no resulta en una respuesta inmune exagerada o peligrosa. Cientos de millones de personas en todo el mundo ya han …
Malia Jones will be live with Dear Pandemic contributor Dr. Chana Davis! Dr. Davis is a geneticist by training and has experience in cancer research, personalized medicine, and nutrition. She’s also the author of Fueled by Science, a blog and podcast. We’ll be talking about mix-and-match vaccines, origins of the COVID-19 virus, and more! ➡️ …
We’re getting more and more questions about herd immunity–are we there yet?! Your own nerdy girl Dr. Malia Jones published an essay on Slate.com this week that’s all about herd immunity, and we know you’ll want to check it out! Three points to take home: 1. Herd immunity is a policy goal, not a light …
Malia Jones of Dear Pandemic and Alison Bernstein of Mommy, PhD and SciMoms are teaming up to talk blood donations, CDC mask guidance, kids’ vaccines, and herd immunity. ➡️ Welcome, Intros, and chit chat (0:00-1:58) ➡️ Will blood donation after vaccination lessen my immunity or provide immunity to the person receiving my blood? (2:00-3:30) ➡️ …
