The Centers for Disease Control and Prevention (CDC), the national health institute of the United States, has predicted that the country will have enough vaccine to prevent coronavirus and return to “regular life” by the third quarter of 2021.

While addressing a Senate panel, CDC Director Dr. Robert Redfield said the vaccinations are expected to start in November or December this year, but due to limited quantities the first doses will be given to the health-care workers.

Redfield was quick to add that the vaccine will take about “six to nine months” to cover the entire American population.

“If you’re asking me when is it going to be generally available to the American public so we can begin to take advantage of vaccine to get back to our regular life, I think we’re probably looking at third … late second quarter, third quarter 2021,” Redfield told the US Senate Appropriations sub-committee.

US President Donald Trump criticized Redfield’s comment while addressing a press conference at the White House.

The CDC issued a clarification Redfield’s remark. “He was not referring to the time period when COVID-19 vaccine doses would be made available to all Americans,” CDC spokesman Paul Fulton Jr. said as quoted by CNBC.
