In a recent interview with CNN, Dr. Anthony Fauci has declared that he would not mind the the upcoming COVID-19 vaccine had a70% to 75% effectiveness, considering the fact that the incomplete protection offered by the vaccine would be worsened by the fact that one third of Americans have declared that they would probably not be willing to get a coronavirus vaccine. If both of these factors pile up, it is not probable that the US will reach herd immunity levels fast enough to actually prevent an outbreak.
In the near future, three different vaccines for the novel coronavirus are going to be studied, due in large part to government support to the cause. Fauci has recently explained that the best vaccine that humanity has ever invented is the one for measles. That one has an effectiveness of about 97, even 98 percent. Fauci is the director of the National Allergy and Infectious Diseases. Continuing his sentence, Fauci explained that he thinks it is unlikely that the US will get to the same level in its first try, but Fauci will still consider himself satisfied if the level of effectiveness is somewhere around 70, or perhaps even 75 percent.
A CNN poll that was conducted last month identified the fact that a third of Americans believe that they would not attempt to get vaccinated against COVID-19, even in the situation in which the vaccine became widely available for the public and its cost was minimal. On Friday, in an interview with CNN, Fauci was asked by CNN if he believes that a vaccine with an efficacy of 70% or 75% would be enough to provide herd immunity, in the case in which it would only be taken by two-thirds of the population. Fauci proceeded to declare that this will probably not be the case, as more people need to get the vaccine.
