The British government said in a statement that the Medicines and Healthcare Products Regulatory Agency (MHRA) has authorized the Oxford University/AstraZeneca Covid-19 vaccine “after rigorous clinical trials and comprehensive data analysis by MHRA experts.”
The statement added that the vaccine has reached “strict safety, quality and effectiveness standards.”
“The NHS has developed a clear vaccine delivery plan and has decades of experience in implementing mass vaccination programs. It has vaccinated hundreds of thousands of patients with Pfizer/BioNTech vaccines and will continue to promote it. Now , The NHS will begin to widely promote the preparation of the Oxford University/AstraZeneca vaccine.”
Andrew Pollard, the lead researcher of the Oxford Vaccine Trial, said: “It’s exciting to find that one of our dosing regimens may be about 90% effective. If you use this dosing regimen, you can The planned vaccine supply will vaccinate more people.” November.
This vaccine was developed by the University of Oxford in the United Kingdom and is much cheaper than other vaccines, and it is crucial that since it does not need to be stored at freezing temperatures, it is easier to transport and distribute in developing countries than its competitors. Much.
Azra Ghani, chair of infectious disease epidemiology at Imperial College London, told CNN: “I think this is the only vaccine currently available in these environments.”
The Oxford/AstraZeneca vaccine can be stored at a refrigerator temperature of 2 to 8 degrees Celsius (36 to 46 degrees Fahrenheit) for at least six months. Moderna’s vaccine must be stored at minus 20 degrees Celsius (4 degrees Fahrenheit)-or at refrigerator temperature for up to 30 days-Pfizer/BioNTech vaccines must be stored at minus 75 degrees Celsius (103 degrees Fahrenheit)) and at high temperatures Use within 5 days of refrigeration.
Garni said: “Pfizer and Moderna need a cold room, but in many cases they don’t.”
“Cold chain” refrigeration is the standard storage facility used globally to transport vaccines from central locations to local health clinics. Garni added that so far, AstraZeneca’s vaccine is “the only vaccine that can definitely be provided to these systems.”
Vaccines are based on different technologies. AstraZeneca’s products-such as Johnson & Johnson’s vaccine and Russia’s Sputnik V-use adenovirus to bring the genetic fragments of the coronavirus into the body.
