BREAKING: Pfizer demonstrates what it sees as proof that third shot will be both safe and necessary for most Americans to take, arguing that immunity wanes over time—regardless of any new variant of concern—according to new data released by the FDA.

And there is growing debate on the timeline for COVID-19 vaccine booster shots. ABC News' Alex Presha reports.The Food and Drug Administration on Wednesday released new data from Pfizer's submitted application to approve booster doses of its Covid-19 vaccine. In it, Pfizer demonstrates what it sees as proof that third shot will be both safe and necessary for most Americans to take, arguing that immunity wanes over time -- regardless of any new variant of concern.

Pfizer/BioNTech, which partnered to develop the nation's first fully approved vaccine, has said it has early data suggesting a booster dose anywhere from six to 12 months after the second dose will help maintain a high level of protection; Pfizer asked the FDA to approve booster doses of its vaccine in late August by submitting an application and data. On Wednesday morning, the FDA made that data public.
