The Archbishop has put out a second letter updating us on the COVID-19 vaccines:

Dear Brothers in Holy Orders,

On December 3, 2020, I wrote to you outlining some of the most important principles regarding the application of the Church’s moral teaching to the production, distribution and reception of COVID-19 vaccines. There have been several developments since then, so I take this opportunity to provide you with a brief update.
The vaccines developed by Moderna and Pfizer to combat COVID-19 may be taken without moral reservation. As indicated previously, the Chairmen of the U.S. Bishops’ doctrine and pro-life committees said in a November 23, 2020, statement that it is not immoral to be vaccinated with the vaccines being developed by Moderna and Pfizer given the seriousness of the health risk.
