Needle Fear among Children during Mass Measles Rubella (MR) Injectable Vaccination Campaign in North India: an Observational Study

The cross-sectional observational study evaluated the prevalence and predictors of needle-fear among school-going children during mass Measles-Rubella (MR) immunization campaign (year 2017) in the north Indian city of Chandigarh. Fear of needle was assessed using a single-item self-report global question, anxiety was assessed using the Likert scale (score 1-5) and the standardized "Children Faces Scale" where facial responses were graded from 0 to 4. Out of a total sample of 2568 school children, 1225 (47.7%) reported needle fear (95% CI: 45.8%-49.6%) on a global single item assessment. On an anxiety related Likert scale, 52.3% did not respond (mainly younger children) and among those who responded, 42.6% (523/1226) showed significant anxiety (score of >= 3 on Likert scale of 1 to 5). Finally, 17.4% children (95% CI: 15.9%-18.9%) (n = 446/2568) scored 2 or above (indicating significant needle fear) on the 'Children Faces Scale' during the actual vaccination procedure. The needle fear were significantly increased among girl students as compared to boys (adjusted OR 2.58; 95% CI: 2.05-3.24, p < 0.001) as well as children accompanied by their parents (adjusted OR 2.05; 95% CI:1.57-2.69, p < 0.001). On the other hand, needle fear was significantly lowered in children studying in private schools as compared to public school children (adjusted OR 0.45; 95% CI: 0.28-0.74, p = 0.002). The needle fear, which was an overriding concern in the minds of girls, children accompanied by their parents, and public-school students, must be proactively addressed for successful mass vaccination campaigns. These findings assume further importance with recent international roll out of COVID 19 vaccine.
