booster jabs are still being rolled out. this year, though, the nhs is really trying to get those groups who are much harder to reach, people who might not have good access to a gp, or to health care in general. this part of essex is home to a community of 2,000 showmen, running fun fairs across the country. relax. at a mobile service near the site, 19—year—old maddison is having her second jab. we've got the fun fair rides, so we're always out, dealing with hundreds of people, day in, day out. if everyone doesn't get the vaccine then we're just going to keep back in the same circle we've been going into for the past two yea rs now. s, life's got to carry on and we've got to get the vaccine, haven't we, i suppose. the nhs staff here say that for communities like this, access to a gp is a major barrier to getting vaccinated, but it is also about correcting some of the myths spread on social media. we're always going to have someone that doesn't want it. we, you know, we can try our best, we can put the messages out there,
