Antibody Response Affects COVID-19 Outcomes in Kids and Adults

Doctors can’t reliably predict whether an adult newly diagnosed with COVID-19 will recover quickly or battle life-threatening complications. The same is true for children. Fortunately, the vast majority of kids with COVID-19 don’t get sick or show only mild flu-like symptoms. But a small percentage develop a delayed but extremely troubling syndrome called multisystem inflammatory syndrome in children (MIS-C). This can cause severe inflammation of the heart, lungs, kidneys, brain, and other parts of the body, coming on weeks after recovering from COVID-19. Thankfully, most kids respond to treatment and make rapid recoveries.

Using R2D2 to Understand RNA Folding

If you love learning more about biology at a fundamental level, I have a great video for you! It simulates the 3D folding of RNA. RNA is a single stranded molecule, but it is still capable of forming internal loops that can be stabilized by base pairing, just like its famously double-stranded parent, DNA. Understanding more about RNA folding may be valuable in many different areas of biomedical research, including developing ways to help people with RNA-related diseases like certain cancers and neuromuscular disorders, and designing better mRNA vaccines against infectious disease threats (like COVID-19).

Is One Vaccine Dose Enough After COVID-19 Infection?

For the millions of Americans now eligible to receive the Pfizer or Moderna COVID-19 vaccines, it’s recommended that everyone get two shots. The first dose of these mRNA vaccines trains the immune system to recognize and attack the spike protein on the surface of SARS-CoV-2, the virus that causes COVID-19. The second dose, administered a few weeks later, boosts antibody levels to afford even better protection. People who’ve recovered from COVID-19 also should definitely get vaccinated to maximize protection against possible re-infection. But, because they already have some natural immunity, would just one shot do the trick? Or do they still need two?
