What are the main features of the AstraZeneca-Oxford vaccine for Corona’s new virus causing COVID-19 and why further studies have been carried out, and is it effective against the new corona strain?
These and other questions we answer here.
How does the AstraZeneca vaccine work?
The vaccine mainly uses a safe way to trick the immune system and make it believe that it deals with a serious infection, generating immune response and memory that can be activated if the body encounters the real virus that causes the disease.
The AstraZeneca-Oxford vaccine uses the so-called “viral carrier”, using genetically modified viruses to deliver genetic shipments to cells and give instructions on how to fight against ‘SARS Cove 2 ‘, such as ‘Trojan horse’.
How effective is it?
The general manager of AstraZeneca said that their vaccine protects 100% of the severe forms of “COVID-19” virus. This effectiveness is important, because it means conditions that are severe and require hospitalization, which are usually high in mortality rates, and put pressure on the health system.
The French newspaper “Le Figaro” said that the British drug manufacture group AstraZeneca discovered, after intensive researches, the “successful and effective equation” of the vaccine directed to fight “COVID-19” virus, which was developed in cooperation with Oxford University.
AstraZeneca laboratory – scheduled to approve the vaccine in the United Kingdom within the coming days – confirmed that it found “the winning formula” to be effective like its competitors “Pfizer-Biontech” and “Moderna”.
In this context, the general manager of AstraZeneca Pascal Soriot said in an interview with “Sunday Times”, “We believe that we reached an effective successful equation”, confirming that the vaccine protects 100% of the severe forms taken by “COVID-19” virus.
Why was an additional study conducted?
Clinical trials of the AstraZeneca-Oxford vaccine showed a 70% efficacy in November, but one protocol, which was mistakenly tested by the British laboratory on a small group of volunteers, showed a 90% effectiveness, prompting the company to conduct an “additional study.”
What is its price?
The AstraZeneca-Oxford vaccine is cheaper, with a dose cost of about €2.5 ($3), compared to about $20 for Pfizer’s vaccine dose, and about $30 for our vaccine dose, indicating that these prices vary according to the volume of orders, news sites reported.
What temperature is needed to store it?
The AstraZeneca vaccine can be stored in the normal refrigerator, at 2 to 8°C, so the AstraZeneca vaccine makes vaccination easier. The “Modrna” and “Pfizer-Bionetech” vaccines pose logistical challenges, because their long-term storage needs to be kept at temperatures below 20 for the first and 70 below zero for the second.
Is the vaccine effective against the new Corona?
According to time, Suriot said researchers believe their vaccine will be effective against the new kind of Corona virus that leads to a rapid increase in injuries in Britain.
When will it begin to be distributed?
“The government has agreed today (Wednesday) to the recommendation of the Drug and Health Product Regulatory Agency to allow the use of the University of Oxford-AstraZeneca vaccine against” the virus, a health ministry spokesman said.
On his part, British Minister of Health Matt Hancock said that the vaccine of Oxford University and AstraZeneca for prevention of Covid-19, which was approved by Britain today, Wednesday, provides an opportunity for survivors from the pandemic by spring.
“The National Health Authority will be able to provide doses to inject people as quickly as they produce,” he told Sky News.
“I am very confident now that this morning we will be able to vaccinate enough people at risk of infection by spring, which will allow us to get out of this pandemic,” he said.
Media reports at the beginning of the week mentioned that Britain will start distributing AstraZeneca vaccine starting from the fourth of January.
