(CNN Español) – The vaccines of Pfizer and AstraZeneca against coronavirus have high levels of efficacy to prevent serious serious illness in patients with risk. This is the conclusion of two studies, one in Israel and another in the United Kingdom.
In this episode, Dr. Elmer Huerta discusses the results of both research and explanations of what are important.

Hello. Soy Dr. Elmer Huerta and this is his diary dose of information about the new coronavirus, information that we hope will be useful to take care of his health and that of his family.
How we see the new studies that evaluate the effectiveness of vacancies against covid-19.
In the first place and as we will see in the episode of February 16, we will distinguish between the terms used in the diary conversation, including the means of communication: efficiency and effectiveness of the vacancies.
What is the efficiency of vacancies?
First we know what constitutes the efficiency of a vacancy.
To achieve efficiencies, we record that Phase 3 studies of vacancies occur over decades of person lives, and their studies are closely monitored by those investigators practically who are seen by the participants.
In other words, to facilitate the comparison of the results, the participants of the phase 3 studies their selected persons, and to include embarrassed women, children, very old persons or pre-existing closed candles.
To conclude the phase 3 study, calculate the vaccine efficacy comparing the number of cases presented in the group receiving the vaccine and the number of cases presented in the group receiving the placebo.
This is the efficiency of some vacancies:
Obviously, if it is hoped, the number of cases in the group receiving the vaccine is much lower than in the group receiving the placebo, it is said that the vaccine is effective.
Here, it was calculated that for the vacancies of:
- Pfizer / BioNTech, its efficiency is 95%,
- For the Modern 94.5%,
- For AstraZeneca 82.4%,
For Johnson & Johnson:
- 72% in United States,
- 66% of Latin America
- y 57% of South Africa.
But what about efficiency?
In terms of efficacy, efficacy studies do not include vaccines in controlled trials comparing placebo vaccines. Provienen to create real-life evacuation campaigns, in which cases the vacancy populations are compared with the vacancies.
Israel and the United Kingdom are, among others, the countries with the most data on our vacancy rates. However, there are only vacancies for the persons, since he designed – and in parallel – studies that allow the effectiveness of the vacancy programs.
In this sense, an Israeli demonstration that the effectiveness of the Pfizer / BioNTech vaccine is:
- 94% to prevent the syntactic infection
- 92% to avoid the worst.
For its part, a British study, unpublished and realized by the AVONCap Foundation (funded by Pfizer) has agreed that a single dose of Pfizer / BioNTech vacancies from AstraZeneca could be very effective in preventing serious psychiatric illnesses. mayors of 80 years with multiple illnesses.
A single dose of Pfizer / BioNTech injection, which began to be administered in the United Kingdom on December 8, had an efficacy rate of 71.4%, 14 days after injection, and prevent patient hospitalization with an ointment the 87 years.
In the same way, a single dose of the AstraZeneca vaccine, which is expected to be administered in the United Kingdom as early as January 4, was 80.4% effective in preventing patient hospitalization with a medium age of 88 years.
It is clear that these dates of effectiveness of vacancies, calculated in real time, are very worrying, since they can show that both vacancies can prevent severe cases of high risk of complications, cases that can lead to hospitalization and death objective in which every person vacated puts his hope.
