Fauci says Covid-19 vaccine might not get us the herd immunity we need

(CNN)Dr. Anthony Fauci says he would "settle" for a Covid-19 vaccine that's 70% to 75% effective, but that this incomplete protection, coupled with the fact that many Americans say they won't get a coronavirus vaccine, makes it "unlikely" that the US will achieve sufficient levels of immunity to quell the outbreak.

With government support, three coronavirus vaccines are expected to be studied in large-scale clinical trials in the next three months.

"The best we've ever done is measles, which is 97 to 98 percent effective," said Fauci, the director of the National Institute of Allergy and Infectious Diseases. "That would be wonderful if we get there. I don't think we will. I would settle for [a] 70, 75% effective vaccine."

A CNN poll last month found one-third of Americans said they would not try to get vaccinated against Covid, even if the vaccine is widely available and low cost.

1. In livestock herd immunity is when 95% are vaccinated.

If the vaccine is only 70% effective and 95% of people are vaccinated than 30% are vulnerable.

2. We'll be lucky to get 75% effective and 75% vaccinated. Very lucky.
