The CDC's COVID Data Tracker shows that as of Thursday morning, just under 6 million people have been vaccinated nationwide, and fewer than 20 million doses have been distributed.
He adds that the arrival of more vaccine is largely dependent on following the state's distribution guidelines, with high-risk health workers and first responders being the top priority. "So let me make that clear", Fauci said.
In a January 7 interview, Anthony Fauci, MD, director of the National Institute of Allergy and Infectious Diseases (NIAID), warned about one COVID vaccine side effect that's been seen in a handful of individuals so far: severe allergic reactions.
Fauci estimated that between 70% and 85% of the USA population will need to be vaccinated to achieve "herd immunity", meaning enough people are protected that it's hard for the virus to continue spreading.

As of midnight, Friday, January 8, the HPSC has been notified of 4,842 confirmed cases of COVID-19 in Ireland. It brings the cumulative number of known cases in Ireland to 140,727 and the country's death toll to 2,336.
Health and Human Services secretary Alex Azar urged governors on Wednesday to open up vaccination campaigns to broader populations rather than "micromanaging" the process of vaccine distribution. "Then you have of course Christmas and New Year's right there", Azar said during an Operation Warp Speed briefing. "That's also a normal effect".
Pharmacies could provide a more efficient platform for distributing the vaccines than hospitals, they said.
Strictly enforcing Centers for Disease Control and Prevention recommendations of giving the first doses of the vaccine to frontline workers and residents of long-term care facilities also has been an issue, according to Azar.
"So, in order to ensure that they don't get reinfected, we do recommend that people who have been infected actually do get a vaccine".
