CURRIE, SCOTLAND - JANUARY 07: A healthcare worker holds a vial of AstraZeneca coronavirus disease (COVID-19) vaccine at the Pentland Medical Practice on January 7, 2021 in Currie, Scotland. The UK aims to vaccinate all over-70s, front-line health workers, and the most clinically vulnerable by mid February, when its current lockdown rules will be reviewed. That would require around 13 million covid-19 vaccinations. As of Tuesday, the country had vaccinated more than 1.3 million people.
You need to take the second shot of the vaccine a few weeks after the first jab was administered. The vaccinated people should get some degree of protection within two weeks of the first jab.
