Testing of the Pfizer vaccine against COVID-19 in which one in a million people took part confirmed that it was very effective in preventing severe and deadly contagions, including the first dose.
The results of a massive campaign of vacancies in Israel avalan the other minor studies, also when it is of a generalized use, between persons of different editions and conditions of health.
The vaccine has a 92% efficacy in preventing severe contagion after dose and 62% after one. It is estimated that the mortality prevention rate is 72% between two and three weeks after the first injection, which means that with time corrections the immunity will increase.
Appears as effective in the mayors of 70 years as in the young.
“This is my tranquilizer. Better than what we think ”, said the director of the Clinic Mayo Gregory Poland.
The doctor Buddy Creech, from the Vanderbilt University, agreed. “Including, however, the first dose we note a great effectiveness in killing prevention”, commented.
None of the specialists participated in the study in Israel, but both had been involved in other work on the coronavirus.
I would like to say that the new results can make sure that the second dose is taken, as is the case with the United Kingdom, or that there is a single dose to be given to the people who have taken COVID-19, like the French, to be able to evacuate more people, even though there are currently no vacancies.
“I would like to see 100 million people with a dose of 50 million with two doses”, said Creech. “It’s my turn to see if it’s with a dose” in the Israeli studio, which published the papers by the New England Journal of Medicine.
The majority of the doses are given in two doses, separated by three weeks, by the vaccine, produced by Pfizer and the German BioNTech laboratory.
The study was conducted by scientists from the Clalit Institute of Investigation and the Ben Gurion University of the Negev in Israel, and the Harvard University in the United States. It is not considered what is the security of the vacancy, only its effectiveness, but other studies will not reveal problems in this area.
Investigators are comparing 600,000 16-year-olds per year, who will be vaccinated in December this year, with a level similar to those of births, sex and health who have not been evacuated. None of the participants had positive results in the past.
The vaccine efficacy in the prevention of COVID-19 syndromes was 57% of the three weekly doses above the first dose, and 94% one week or more after the second.
Efficiency was 74% after an injection and 87% after two hospitalizations and 46% and 92% after confirmed contractions.
The reduction in the number of infections can help prevent the spread of the virus, but this study can not determine if it really is.
There have been 41 deaths associated with COVID-19, 32 of them between those not evacuated.
Poland says that the effectiveness of the vaccine exceeded the first dose was one of the great interrogators and that “now we have some information” to take into account.
“It’s the best way to protect the Mayor from the possibility of a dangerous people … it should give a dose of the possible antiquities”, commented Poland. “I believe it is a strategy that needs to be considered”.
Israel has been evacuated since the beginning of its occupation. During the study, a new variant of the virus was identified, first identified in the United Kingdom, which became the dominant one in Israel, due to the results and some clues regarding the effectiveness of the vaccine against the new variant.
This week, studies conducted in Cape Town in the United Kingdom will also reveal good results after a dose of the Pfizer vaccine and AstraZeneca also. In Great Britain, it is already 12 weeks since the second dose to vacate the mayor’s term of office.
