According to CovidAlertPa, established by the state Department of Health, there were zero new cases of Covid on Sunday in Northampton, Lehigh and Carbon Counties. Monroe reported two, Berks had eight and Bucks had just one. These are the lowest figures I've seen since the state (and counties) began tracking the pandemic. While it's premature to declare victory, we certainly are headed in that direction.
How many of these new cases are from the vaccinated. Strangely, Pennsylvania fails to track this important data point. According to the Inky, Covid among the vaccinated is tracked in New Jersey, Delaware and Philadelphia. Only two percent of new Covid-19 cases are among those who've been vaccinated. This means the vaccines approved for emergency use have a combined efficacy rate of 98%.
