Even if the AstraZeneca vaccine remains in the hospital, there are not many people who will get it. There have been reports of side effects and that it is more susceptible to delta mutations than other vaccines, but it is not necessarily so.



What is the reality, medical reporter Cho Dong-chan will explain in detail.



<Reporter> In



Korea, the number of breakthrough infections confirmed after completion of vaccination is 65.7 cases per 100,000 Janssen, 31.4 cases from AZ, 12.2 cases from Pfizer, and 4 cases from AZ-Pfizer cross-inoculation.



Although there are differences between vaccines, the total combined is only 0.02%.



This time, it's a delta mutation prevention effect.



Even in the UK study, AstraZeneca was slightly lower at 67% compared to Pfizer's 88% on a two-dose basis.



However, with respect to the delta mutation that drives the fourth wave, there is an evaluation that comparing the effect with the prevention rate is meaningless.



A study by a US research team found that the severity of the delta mutation is much more important than whether it is a breakthrough infection.



This is because seriously ill patients infected with the delta mutation are much more contagious than the conventional virus.



A study conducted by the UK Health Authority showed that Pfizer, Moderna and AstraZeneca were all over 85% effective in preventing severe delta mutations.



There are also results that AstraZeneca has greater benefits for young people.



[Jeong Eun-kyung/Director of the Korea Centers for Disease Control and Prevention: In Australia, as the quarantine situation has changed due to delta mutation, the recommended age for vaccination has been lowered to 18.] In



fact, as a result of an analysis in Australia last June, the fatality rate of coronavirus was 0.05% for 40s and 0.013 for under 30. was %.



On the other hand, the mortality rate from blood clots after receiving the AstraZeneca vaccine was lower for all age groups.



Based on this, Australia lowered the age at which the AstraZeneca vaccine can be vaccinated in the middle of last month, before the Moderna vaccine supply insecurity.
