Fauci: 3rd shot likely going to become standard regimen
In an interview with the podcast “In the Bubble,” Dr. Anthony Fauci told former White House adviser Andy Slavitt that he predicts three doses will become the standard dosing regimen for COVID-19 vaccines going forward.
Fauci cited new data from Israel that vaccine protection against hospitalization dropped in recent months from some 97% to 77% or 78%.

The vaccines still provide extraordinary protection, but the combination of the delta variant and waning immunity with time are causes for concern, he said.
Fauci added that that he thinks it will probably be the end of 2022 or early 2023 before much of the world is vaccinated.
