AstraZeneca has figured out how to increase the effectiveness of the COVID vaccine

The vaccine against COVID-19, developed by the British-Swedish pharmaceutical company AstraZeneca and the University of Oxford, showed effectiveness after the first dose.

According to a new press release from the company, such results were obtained from a preliminary analysis of the third phase of clinical trials of the drug.

So, after the first injection, the vaccine was 76% effective in general and 100% protects against severe illness, hospitalization, and death. In addition, even if infected, the vaccine will reduce the likelihood of transmission of the virus by almost two-thirds.

The report also says that if you postpone the second injection in time, the effectiveness will increase. As it turned out, if the second dose is administered six weeks after the first, the effectiveness will be only 55%, but if this interval is increased to 12 weeks, the effectiveness rate will increase to 82%.

As a reminder, early studies showed AstraZeneca vaccine efficacy at 62% with two full doses and 90% with one and a half doses.

We also wrote that German doctors recommended using the AstraZeneca vaccine only for patients between the ages of 18 and 64.
