The effectiveness of the AstraZeneca vaccine is greater when the second dose is given 12 weeks after the first. These are the findings of a new study published in the scientific journal The Lancet.
The news is likely to be welcomed by countries facing a new wave of new variants of the virus and trying to vaccinate as many people as possible with the first dose and postpone the second.
According to a study published in the authoritative journal, three months after the first dose of AstraZeneca, its effectiveness is 76 percent. The survey confirms the data announced by the manufacturer from the beginning of the month.
Thus, the effectiveness is 81% after the second dose if the interval is 12 weeks and 55% if it is given after six weeks. The study also confirms the recommendations of the British health authorities for a longer interval between dosing and those of the World Health Organization.
Meanwhile, British Prime Minister Boris Johnson has promised that by the end of July, all Britons over the age of 18 will have access to the first dose of the Covid-19 vaccine. Mass vaccination is also starting in Australia. There are not many coronavirus infected people in the country compared to the rest of the world.
And nearly 40 homeless people, including the disabled, have been vaccinated against Kovid-19 in St. Petersburg. A similar initiative, supported by local authorities, was recently launched in Moscow.
