Billy Penn is tracking vaccinations in Philadelphia and Pennsylvania.
The goal of any vaccine program is to reach herd immunity, which essentially means enough people bear resistance to a virus that it cannot find enough hosts to propagate within a given community. It then stops spreading without major mitigation efforts.
Health officials have estimated that with COVID-19, the post-pandemic Valhalla might occur when 70% to 80% of the population is immunized.
Since people flow in and out of Philadelphia on a regular basis, for work and other reasons, herd immunity is also dependent on the situation in the collar counties. The map below shows vaccinations in the region, according to data from the U.S. Centers of Disease Control and Prevention.
Philadelphia has a separate vaccine program than the rest of Pa., so dose delivery is tracked separately.
You can view progress in getting people vaccinated on a city and state level in the charts below. They’ll update almost daily, so bookmark this page and check back often.
