Reporter good evening, weve been eagerly awaiting this news from pfizer, in came in a press release. The n. I. H. s Anthony Fauci said he believes some people may be able to get the vaccine before the end of the year. As cases continue to surge, pfizers news is seen as a major boost in the fight against coronavirus. All the stars are starting to align very, very nicely. Again you never want to get ahead of yourself but this initial news from the company is extraordinarily encouraging. Reporter in a trial of 44,000 participants, half got two doses of the vaccine and half a placebo. Analysts looked at 94 participants who came down with symptomatic covid19. Seven days after the second dose the vaccine was more than 90 effective in preventing disease. We were jumping out of the chairs, screaming. We may put an end to this terrible pandemic. Reporter pfizers chief scientific officer dr. Michael dolsten. It feels to me that this is one the biggest if not the biggest medical advance in the last hundred years. Reporter pfizer says it could be ready to apply for f. D. A. Emergency use authorization in the third week of november. The u. S. Government has paid pfizer nearly 2 billion for a hundred million doses. Even if the vaccine is authorized, most americans wont have access to it until at least the spring of 2021. Oure talking about efficacy if it holds that is on the level of say the childhood vaccines like measles. It is 90 plus, so this is extraordinary. We have accomplished, you know, in eight months. Odonnell and dr. Lapook joins us now. So this almost sounds too good to be true. Is it . Reporter well, we hope if is well, we hope if true. But there are still some questions. First of all, if it is effective, how long will the heotection last. Protection last. And second o and second of all, how do you roll out Something Like this to hundreds of millions of americans especially when the vaccine has to be kept at such a low temperature. And finally who gets it. The triage process, for people who are first line responders and for people who are vulnerable, they may get it frst. And then the question of people saying there is no way im taking it. Dt as dr. Fauci told me, when you have a vaccine that is 90 effective during the middle of a deadly pandemic, that may change a few minds. Odonnell yeah, some real hope. Dr. Jon lapook, thank you.
