$BCRX Based on my research thus far, $MRNA and $BCRX are currently the frontrunners in SARS-CoV-2 vaccine development due to their previous research and development on RNA viruses. I've invested in both companies since mid-February 2020, and have been fairly accurate buying and selling the MRNA dips and increases. Regarding BCRX, although it has been frustrating at times, I'm holding my shares, as I firmly believe that this stock will remain on a steady incline for the foreseeable future based on available information and potential outcomes. Best of luck everyone!
