Fauci said Moderna could be delayed a bit, and if so, instead of having a simultaneous launch of both products, Moderna could happen a week or two later.
"I don't think that's an important issue, but we would have liked to have them all together, simultaneously. But in the end the plan will be implemented, as outlined," Fauci said.

Study: Moderna doses protect against 0:48 delta variant
Fauci said that ultimately, the appropriate immunization regimen against COVID-19 may turn out to be three doses.
"What we are seeing now, not just here in the United States but in other countries, including Israel and the United Kingdom, is that the durability of the protection tends to decrease, particularly in the context of the delta variant," Fauci told CNN. .
He explained how such a decrease can lead to both infections from vaccinated people and infections from vaccinated people leading to hospitalizations.
"If you look at the evidence from the cohorts here in the United States, there is no question that there is a decrease in the efficacy of the vaccine against infection, that is, symptomatic infection. There is a slight suggestion in a couple of the cohorts that it's also true for a decrease in protection against hospitalization - it's not profound, but the suggestion when you look at the data is there, "he said.

"However, when you look at the Israeli data, and they are about a month ahead of us in all aspects of this (vaccines, boosters, etc.), the data from the Israeli studies indicates that there is a decrease in protection against infection and an undeniable decrease in protection against hospitalization. "
Fauci said the good news is that data from Israel shows that booster doses offer "profound" protection against infection and hospitalization.
"Importantly, their data also shows that when these boosters are given, protection against infections and hospitalizations is reconstituted to an even higher level than before," Fauci said.
"The boosters really increase the response very, very high, and we hope that response will be long-lasting."
