Yves here. It’s good to see Tom Neuburger discussing a possible misperception by some of what the “95% effective” Covid mRNA vaccine results touted by Pfizer and Moderna mean, when they are on the verge of receiving an FDA Emergency Use Authorization to allow their release. While we have your attention, we’ll point out another misperception, which the press is amplifying, that having been vaccinated would prevent the recipient from transmitting Covid. For instance, some business owners are saying they will require employees to be vaccinated, not because they are concerned about worker safety, but because they intend to market their venue as safe for customers by virtue of having vaccinated staff.
