What the heck is a fomite?

Staying Safe

A. TL; DR: The term fomite refers to a contaminated surface or object (e.g., serving spoon, door knob) that allows for the transmission of an infectious agent. The good news is that fomite transmission is not common for the virus that causes COVID-19. The Nerdy Girls love words! Let’s take a dive into the origin Read more…

Based on information gathered from Emily Oster’s recent article in The Atlantic, can I consider it safe for children to travel and have unmasked/indoor playdates, especially looking ahead to summer?

Families/Kids Staying Safe Vaccines

A: No. Dr. Oster’s article did not suggest that it’s safe for children to have unmasked playdates and return to 100% normal life this summer. As science journalist Tara Haelle put it, “it’s fine for your unvaccinated kids to go on a road trip and hug their vaccinated grandmas. It’s just not okay to pretend Read more…

¿Cuál es la diferencia entre los anticuerpos que se generan después de haber contraído COVID-19 versus los anticuerpos que se generan después de vacunarse?

Biology/Immunity Posts en Español Vaccines

R: La diferencia radica en que los anticuerpos que se forman después de una infección reconocen diferentes partes del virus mientras que los anticuerpos que se forman después de la vacunación reconocen específicamente la proteína de pico. Algunas pruebas de anticuerpos no detectan la presencia de anticuerpos contra la proteína de pico, sino más bien Read more…

¿Las precauciones existentes funcionan para proteger contra la nueva cepa de COVID-19?

Infection and Spread Posts en Español Staying Safe

Por suerte, si. La nueva cepa de COVID-19 es más transmisible que la cepa anterior. Pero, esto no significa que nuestras precauciones habituales (utilizar mascarilla, 2 metros de distancia, estar al aire libre) son menos efectivas. Las mutaciones de virus aún no desafían las leyes de la física. Pero debemos estar más atentos a las Read more…

When we need a booster for the new variants, will we need to have the same company’s vaccine as our first?

Biology/Immunity Vaccines

A: If booster shots or vaccines adapted to new variants of the SARS-CoV-2 virus become necessary, it is likely they will be able to be used by those originally vaccinated with a different type of vaccine. This strategy might even have added benefits! While it is currently not recommended that we mix and match COVID-19 Read more…

I’m fully vaccinated, but my kids are not. What does the new United States CDC guidance for fully vaccinated people say about our situation? I am so confused.
