Currently, there are three authorized and recommended vaccines to prevent COVID-19 which are being distributed throughout Pennsylvania, including in Chester County and Delaware County. (More information on the Pfizer-BioNTech, Moderna and Johnson & Johnson vaccines can be found below)
The Pfizer-BioNtech and Moderna vaccines require two doses for full effectiveness - a second shot is given either 21 days (Pfizer) or 28 days (Moderna) after your first shot to get the most protection the vaccine has to offer against COVID-19.
The Johnson & Johnson vaccine requires one dose.
Additional vaccines are in development.
The Moderna and Johnson & Johnson vaccines are only approved for individuals 18 and older.
The Pfizer vaccine is approved for individuals 12 and older
