President Biden showed reporters receiving a booster vaccine at the White House today (28th).



It has been four days since the limited booster vaccination was approved, but it seems that the vaccination rate has been stagnant, considering the situation.



[Biden/President of the United States: 23% of Americans have never been vaccinated. That small number is causing great damage to the rest of the United States.] The



average number of new cases per day in the United States, which has soared to over 170,000 a day, is slowly fading.



Last week, the average number of new confirmed cases per day fell to the level of 119,000.



However, as the weather gets colder in the future, there is a strong prospect that the spread of infection will continue for the time being due to more indoor activities.



As this trend continues, as the number of people with immunity from vaccination or corona infection increases, there is also a forecast that the fourth re-spread will subside by the end of November.



[Gotlieb/Former Food and Drug Administration Director: By Thanksgiving, we will see this trend across the United States. The virus will not go away, but the level of prevalence seems to drop to a manageable level.]



Pfizer, which is testing a vaccine for children under 12 years of age, said it has entered a phase 2 clinical trial for a COVID-19 treatment in pill form.
