The AstraZeneca/Oxford Covid-19 vaccine maybe 85% to 90% effective in preventing symptomatic disease in the real world. This was revealed in the data released by the United Kingdom.
Preliminary results released by Public Health England (PHE) highlight for the first time the effectiveness of two doses of the AstraZeneca vaccine in real life.
However, the results said that the efficacy could not be relied on yet and more evidence needed to be gathered for verification. The Public Health England Weekly Report estimates the effectiveness of the AstraZeneca vaccine at 89%.
According to the report, this vaccine developed by Oxford University is as good as the Pfizer vaccine to prevent the disease of Covid symptoms which is 90% effective.
Nadhim Zahawi, the UK’s vaccine minister, said the new data showed the amazing effects of the two doses of the AstraZeneca vaccine, which can provide up to 90 percent protection against the disease after a second dose.
Preliminary results were also welcomed by AstraZeneca. The company spokesman said, Large and real-world data add to the evidence that our vaccine is effective against Covid -19.
The United Kingdom is the first country to introduce the AstraZeneca vaccine. Pfizer and AstraZeneca vaccines have been used there since December 2020 and January 2021, and Moderna was approved in April.
Public Health England reported that a slight decrease in the effectiveness of the Pfizer vaccine 10 weeks after the first dose occurs before the second dose.
Pfizer vaccine doses in the UK are being given a 12-week break, although the company warned that there was no evidence of a procedure other than a 3-week break.
