Almost a year after the first Covid-19 jab was administered, the most at risk are now being asked to get the third vaccine.
Those who are currently eligible for getting a third dose of the Covid vaccine are people are “most at risk from Covid-19 who have had a second dose of a vaccine at least is months ago,” according to the NHS.
Currently, this includes people who are aged 50 and over, people who live and work in care home, frontline health and social care workers, people aged 16 and over with health condition, and people aged 16 and over who live with someone who is more likely to get infections.
What are the side effects of the booster vaccine?

As with any vaccine, side effects can occur and vary from person to person.
The most common Covid-19 vaccine side effects are muscle and joint pain in the arm where the jab was injected, fever, chills fatigue and a headache.
More specifically, side effects from the Covid vaccine booster shots are similar to those felt after the second dose, and are more likely to affect younger people, according to Pfizer.
Pfizer submitted the findings, which involved a study of 300 participants, to the US Food and Drug Administration.
The study fond that 63/7% of the participants, who were aged 18 to 55, experienced fatigue after getting their booster jabs.
