For a large part of thecoronavirus pandemicPeople have been attached to the perspective of a Covid vaccine that can contain hatching and finally bring a return to normality. And with many speculating health experts than aThe vaccine could arrive at the end of the yearIt's hard not to feel optimistic about things improving in the near future. At a hearing in the Senate of 16 September, however, centers of Director of Disease and Prevention (CDC)Robert R. Redfield, MD, offered a slightly less pink prediction:This could take up to nine months for the American public to have vaccinated.

"I think we have to assume that if we had a vaccine, say, published today, that it will probably take us in the order of nine months, six toNine months to get the American public vaccinated"Redfield told a senatorial committee." In order to have us quite immunized, so we have an immunity, I think it will take us six to nine months. "

REDFIELD is not the first expert on the prudence that the production and distribution of vaccines could take longer than many of us would like to believe.Adar Poowalla, CEO of Serum Institute of India, the largest vaccine manufacturer in the world, recently stated that it would takefour or five years for everyone to have vaccinated globally.

The vaccination of the Americans is of course a closer perspective, but the prediction of Redfield falls online with what others have warned. In AugustWashington Post Article Le MIT, "Deploying the vaccine to people in the United States and around the worldTest and stress distribution networks, the supply chain, public confidence and global cooperation. "

The chronology of the vaccine The director of the CDC gave was not the only verification of the deflating reality he offered. Redfield also said thatFace masks can offer more protection than a Covid vaccine, echoing the concerns of shared health experts on howEffective the first vaccine will actually be. While scientists target a vaccine of at least 75% effective, the administration of food and drugs will approve a person who isOnly 50% effective.

Beyond that, there are questions about how many people will beReady to get the vaccine. While Redfield talked about the need to get enough Americans vaccinated to reach herd immunity, this can be impossible with a vaccine at only 50% effective and one third of the AmericansRefuse to be vaccinated, as some recent polls suggest.

At this point, health officials and infectious disease experts can only offer forecasts and not a concrete timetable for the future of the pandemic. There is no doubt that the development of a vaccine would change the course of the epidemic in the United States - but any person impending an imminent return to normal life may have to temper their expectations. And for more occupificacy of the CDC,40% of the cooviding patients went here before getting sick, said CDC.
