Q. How to transport and store?
Ease of storage is the biggest advantage of the AstraZeneca vaccine.
It can be stored for up to half a year if it is kept refrigerated between 2 and 8 degrees.
It is said that it can be easily stored and vaccinated anywhere in most local clinics.
On the other hand, Pfizer vaccines, which begin vaccination tomorrow, are difficult to store.
The vaccine is easily damaged at room temperature because it is developed using the advanced mRNA method.
It must be kept in a cryogenic condition of -70 degrees Celsius throughout the entire process from transportation to storage.
For this reason, the government has also deployed cryogenic freezers at each vaccination center for Pfizer vaccine.
Pfizer vaccines must also be processed prior to vaccination, such as thawing and dilution during vaccination.
Q. Effect · What is the inoculation interval?
AstraZeneca vaccine has been tested in the UK and Brazil with only 60% preventive effect.
This is less than the 95.1% Pfizer vaccine.
However, when it comes to the prevention of severe infections, the AstraZeneca vaccine reached 94%, higher than the 85% level of Pfizer.
Both vaccines need to be taken twice, which will increase the preventive effect.
The first and second vaccination intervals were 3 weeks by Pfizer, while the AstraZeneca vaccine was 8 to 12 weeks, and the AstraZeneca vaccine showed the best effect at 12 weeks.
AstraZeneca vaccine can be administered to 10 people per bottle and Pfizer vaccine can be administered to up to 6 people if the remaining vaccine is minimized using a special syringe.
