Effective compared to Pfizer and Modena ↓, better than flu vaccine
Rapid increase in mutant virus infection also affects urgent approval ↑
British health authorities approved the urgent use of a new vaccine against coronavirus infection (Corona 19) jointly developed by the world’s first multinational pharmaceutical company, AstraZeneca, and the University of Oxford on the 30th (local time).
However, Yonhap News reported on the 31st, citing foreign media such as Reuters, that the AstraZeneca vaccine has yet to apply for approval from the European Medicines Agency (EMA) and the United States Food and Drug Administration (FDA). .
The AstraZeneca vaccine is reportedly expected to be approved after at least February 2021 before vaccinating the general public in the European Union (EU) and the United States.
The vaccine developed by the University of Oxford and produced by AstraZeneca was the most promising candidate vaccine against Corona 19 in the early days of vaccine development. The first developed in the world was AstraZeneca.
However, this vaccine has been noted as a major weakness compared to other vaccines due to the controversial immunity effect of rubber band and the omission of key data and information.
The Pfizer vaccine has an immunological effect of 95%, and Modena also reaches 94.5%, while AstraZeneca has an average of 70.4%.
However, the preventive effect of participants who received half the dose of AstraZeneca vaccine first and then received the correct dose about a month later rose to 90%. On the other hand, the preventive effect of those who received the full dose at both times was reduced to 62%. In this regard, more research and investigations are needed.
Consequently, the UK health authorities approved the use of the AstraZeneca vaccine twice in a full dose.
The prevention effect of this method is low at 62%, but the prevention effect is known to be high with increasing the interval between 1 and 2 doses. In particular, none of the people infected with COVID-19 after the vaccine had worsened to a serious condition.
In addition, the World Health Organization (WHO) determined that it could be used if the preventive effect of the Corona 19 vaccine was at least 50%, and Anthony Pouch, director of the National Institute of Allergy and Infectious Diseases, also said that it is fine. use it if it has a 50-60% preventive effect. It has been revealed.
Also, the AstraZeneca vaccine is somewhat ineffective compared to Pfizer, Moder, and vaccines, but it has the advantage of being cheap and easy to distribute.
Pfizer vaccine should be transported at minus 70 ° C ± 10 ° C, but if the vaccine is thawed at the site of dosing, it can be stored for up to 5 days at 2-8 ° C.
Vaccination is also delayed in countries that have approved Pfizer vaccines, such as Germany and Spain, due to storage and transportation difficulties. The UK, which launched the world’s first Pfizer vaccination on the 8th, also vaccinated 800,000 people over 20 days.
On the other hand, the AstraZeneca vaccine is very inexpensive and can be transported, stored and administered for at least 6 months at a normal refrigerator temperature of 2 to 8 degrees Celsius.
In addition, due to the easy storage method, it is expected that more than 1 million people can be vaccinated per week if the vaccine can be vaccinated not only at the vaccination center, but also at the regional health doctors (GP) and pharmacies that do not have separate storage facilities. .
Notably, the AstraZeneca betrayal has already sold 100 million doses as a domestic vaccine (a vaccine based at the University of Oxford in the UK and in the UK and Sweden). Of these, 40 million servings will be available by the end of March next year, according to British health authorities.
Furthermore, the number of people infected with Corona 19 is increasing rapidly in the UK recently due to the emergence of the Corona 19 mutation.
The number of new confirmed cases per day registered 41,385 on the 28th, surpassing 40,000 for the first time in history. On the 29th, in a single day, the number of new confirmed cases exceeded 50,000, reaching 53,135.
Countries around the world have banned or restricted entry to the UK for the first time the mutant virus was found. In this situation, the UK government seems to have analyzed that only large-scale vaccines with the approval of the AstraZeneca vaccine can prevent rapid spread.
