Thankfully, the most high risk people in Brazil have gotten two shots by now; we're moving towards giving a first shot to every adult, and starting second shots for everyone.

We're also having the same discussions about third dose... Currently, the order is to give a third dose for the elderly (70+) and immunocompromised.
