Shortly after British health authorities approved the emergency use of the AstraZeneca vaccine, experts involved in the approval held a press conference.

First, it was introduced that the immune effect of this vaccine increased by up to 80% when a 12-week and 3-month interval was placed between the first and the second.

He explained that only 22 days after the vaccine was given, the partial immune effect would appear and last at least 3 months.

The vaccine has been approved for use in people 18 years of age and older, and says it could be vaccinated by pregnant or mothers with greater potential benefits.

However, he admitted that the reason why the immunity efficacy varies depending on the dosage is not fully proven.

Earlier, the AstraZeneca vaccine showed an average immune effect of 70.4% during clinical trials.

However, in the course of the trial, if by mistake the first dose was administered half the dose and the second dose was the full dose, the preventive effect increased to 90%.

The Pfizer vaccine was 95% effective and the Modena vaccine 94.5% effective.

The U.S. Food and Drug Administration’s FDA has not explained why the efficacy varies depending on the dose of the first and second vaccines.

However, British authorities say it is difficult to compare the results, as there have been no trials comparing Pfizer and AstraZeneca vaccines approved for use.
