When it comes to the COVID-19 pandemic, Dr. Gregory Poland, an infectious diseases expert and head of Mayo Clinic's Vaccine Research Group, says there's some good news. "Case numbers are falling, masking and distancing do work, and we can control this if we do it right." However, the not so good news is that variants are showing up in over 30 countries and are reportedly more transmissible. There also seems to be a reduction in vaccine efficacy against the new variants. "This is a desperate race between vaccine and virus, between time and opportunity, and we dare not lose that opportunity," emphasizes Dr. Poland. (Published 02/03/2021)
