Single dose of AstraZeneca vaccine could result in 96.7% immunity in 4 weeks
A study of 61 patients shows that people who received the first dose of the AstraZeneca COVID-19 vaccine have achieved 96.7% immunity within a month, compared to those who had recovered from the disease for 1-2 months, who have 92.4% immunity.
The study results were published by Dr. Yong Poovorawan, an expert virologist from Chulalongkorn University, on his private Facebook page.
According to the study, female patients gain higher immunity than male patients, while those under 60 years old gain higher levels of immunity.
For this study to be completed, however, there must be more information about patients who have received the second dose, which experts predict, will keep their immunity very high.
Dr. Yong said that, based on this information, the immunity, after only one dose of AstraZeneca vaccine, is considered impressive.
Dr. Yong suggested that the inoculation process should cover as many people as possible, even with only one dose of vaccine. He added that, if 10 million people are inoculated each month, at least 30 million people would have immunity against the disease within three months.
