US Could Reach Herd Immunity By May 2021 If 70% Of Americans Get The Vaccine, Top Doctor Says


America could reach herd immunity by May of next year if a majority of citizens are vaccinated, a prominent health expert told CNN’s Jake Tapper Sunday.

Dr. Moncef Slaoui, the chief scientific adviser for President Donald Trump’s immunization program Operation Warp Speed, told Tapper on his show “State of the Union” that if 70% of the populace receives a coronavirus vaccine, the U.S. could reach herd immunity by May 2021. The achievement of mass immunity is key for the return to “normal life” for Americans, according to Slaoui.

“So normally with the level of efficacy that we have — 95% — 70% or so of the population being immunized would allow for true herd immunity to take place,” the chief scientist told Tapper. “That is likely to happen somewhere in the month of May or something like that based on our plans.”


Major pharmaceutical companies Pfizer and Moderna have both introduced potential COVID-19 shots with an effectiveness greater than 90% in initial testing, according to the Washington Post. Pfizer applied for emergency approval for its vaccine, which could make the injection ready for use in the coming weeks, the New York Times reported.

Slaoui projected a similar timeline in his CNN appearance.

“Our plan is to be able to ship vaccines to the immunization sites within 24 hours of approval,” he said. “So I would expect maybe on day two after approval, on the 11th or on the 12th of December, hopefully, the first people will be immunized across the United States.”

A total of 58% of Americans said they would take a COVID-19 vaccination, according to Tuesday Gallup poll. Fifty-three percent of Democrats and 49% of Republicans indicated they would take an immunization if it was available, the poll revealed.

Slaoui said he was committed to changing the public’s perception of the vaccination.

“I really hope and look forward to seeing the level of negative perception people have about the vaccine decrease and positive perception increase,” he said. “Most people need to be immunized before we can return to a normal life.”

The American people will achieve herd immunity when most individuals in America exert the will and courage to achieve herd immunity individually.

This means science dictating mass behavior, NOT opinion-based dictates signed-off by belligerent technocrats pretending to know the Scientific Method.


Individual herd immunity? Absurd nonsense and misinformation.

No idea what the word ‘context‘ means?

Absurd laziness and human language abuse.


No idea what the words ‘happy’ and ‘realist’ means?


So many deaths. It’s a disgrace.

C. Collier

So many deaths? Seriously? Approximately 250k out of about 12m alleged infections is about 2% of those folks dying *with* COVID, out of 330m (approximate population of the US). And the figure most often bandied about is that 94% of the decedents had severe co-morbidity factors. And who really accepts the numbers they feed us about the infections? I recently heard (from an MD being interviewed) that each positive test is counted as a separate case. So, as example, John Smith gets a positive test from one type of test. They count that as a case. Then, they do a confirmation test on John Smith. They count that as an additional case. Two for the price of one. And then Newsolini uses that as an excuse to exercise even more of his (already found unlawful by the courts) power.

This is worth surrendering our freedoms and Constitutional rights? This is worth the destruction of the American economy? Not in my book.


You think it is your right and freedom to be a reckless and unmitigated vector of disease? That’s disturbing!

The MAGA death cult is still thriving, somehow.


I think there is a very good chance America will be great again – no thanks to the people who conflate liberty with bloody-mindedness.

C. Collier

It”s so sad to be a frightened little mouse, isn’t it?

To be a “vector”, one has to be carrying a disease. I’m not carrying it. I’m not worried for me and, to be blunt, I don’t care about you.

Your selfishness was abundantly clear even before you said that.

I wonder if “comorbidity” includes obesity? If so America is doomed.
