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

First, the vaccine introduced that the immune effect increased by up to 80% when an interval of 12 weeks and 3 months was placed between the first and second doses.

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

The vaccine has been approved for use in people over the age of 18, and it says pregnant women or mothers could vaccinate it with greater potential benefits.

However, he admitted that the reason why the efficacy of immunity varies by dose is not fully proven.

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

However, over the course of the trial, if the first dose was given half the dose by mistake 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%.

The US Food and Drug Administration FDA has not explained why efficacy varies depending on the dose of the first and second vaccines, and it is negative to approve the use of the AstraZeneca vaccine.

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