Therefore, adequate support should be offered to enhance knowledge levels in schools and in the community to provide an adequate environment which influences adolescents to make decisions competently. The strengths of this study include that we focused on adolescents who are a key population at this time following recent announcements internationally authorizing booster doses in this population. more than 5 months ago. Participants and their guardians performed self-reported questionnaires regarding reasons for receiving the booster. A 30 ug booster dose of BNT162b2 was offered. AS-605240 Immunogenicity was evaluated by a surrogate virus neutralization test (sVNT) against the Omicron variant, and anti-spike-receptor-binding-domain IgG (anti-S-RBD IgG) taken pre-booster and 14-days post-booster. From March to April 2022, 120 healthy Thai adolescents with a median age of 15 years (IQR 14C16) were enrolled. sVNT against Omicron pre- and post-booster had 11.9 (95%CI 0C23.9) and 94.3 (90.6C97.4) % inhibition. Geometric means (GMs) of anti-S-RBD IgG increased from 837 (728, 953) to 3041 (2893, 3229) BAU/mL. Major reasons to receive the booster vaccination were AS-605240 perceived as vaccine efficacy, reduced risk of spreading infection to family, and safe resumption of social activities. A booster dose of BNT162b2 elicits high immunogenicity against the Omicron variant. Motivation for receiving booster doses is to reduce risk of infection. = 60)= 91)= 31)Post-Booster (= 31) 0.001). For the 31 samples in the paired group, pVNT against the Omicron variant was performed. The results showed that, post-booster vaccination, neutralizing antibodies against the Omicron variant could be detected at a very high level with a pVNT50 value of 912 (622C1507). 3.3. Attitudes toward COVID-19 Infection and Factors Involved in Getting COVID-19 Booster Vaccination of Adolescents and Their Parents The attitudes toward COVID-19 infection and vaccination of adolescents and their parents are summarized in Table 3. Perception of COVID-19 as a serious disease among the guardians was AS-605240 88.3% compared to 73.3% among adolescents ( 0.01). Guardians more actively searched for COVID-19 vaccine information (85.8%) and thought that the information about COVID-19 vaccines they received was reliable (90.0%), when compared to adolescents at 53.3% ( 0.01) and 80.0% ( 0.05), respectively. Overall, 98.3% of guardians intended for their children to get booster vaccinations against COVID-19, while 89.2% of adolescents intended to get vaccination for themselves ( 0.01). Similar proportions of guardians and adolescents thought that COVID-19 booster vaccines are necessary for children and adolescents (94.2% vs. 98.3%, 0.05). There was no significant difference between guardians and the adolescents opinion about COVID-19 vaccines safety and efficacy in preventing infection. Table 3 Guardians and adolescents attitudes toward COVID-19 disease and COVID-19 vaccines. = 0.03). We decided to group two options together: family or friends recommendation and people in community obtaining COVID-19 vaccination for adolescents and combined them into influences from others as we found a highly significant difference for influences from others as a higher choice in adolescents, compared to guardians (14.2% of adolescents, 1.7% of guardians; 0.01). Table 4 Top three reasons underlying intention to receive the BNT162b2 booster dose in guardians and adolescents. 0.001) stated their reason for a booster dose was the influence from those around them such as friends, family, and the greater community. Several theories exist that hypothesize adolescent decision making is different to that in adults due to their decision-making process being heavily modulated by social influence [45,46]. Therefore, adequate support should be offered to enhance knowledge levels in schools and in the community to provide an adequate environment which influences adolescents to make decisions competently. The strengths of this study include that we focused on adolescents who are a key population at this time following recent announcements internationally authorizing booster AS-605240 doses in this population. Additionally, we used laboratory markerssVNT and pVNTand determined the immunogenicity of a Rabbit Polyclonal to TACC1 BNT162b2 booster against Omicron, the dominant strain at the time we carried out this study. Additionally, we evaluated both adolescent and guardian underlying intentions to get the booster vaccination. Limitations include that we used an in-house surrogated viral neutralizing antibody AS-605240 rather than the conventional or pseudo virus neutralization test as we tested the pVNT only in post-booster samples of the paired group. However, this test has been trialed and revealed good correlation with conventional and pseudo virus-based methods. Our acceptance rates of the vaccine might have an underlying bias as almost all of study participants knew they would receive a booster dose in this study and therefore those not wanting a booster dose at the time did not sign up and were not included in our study. This also translates to their intentions for getting the vaccine as they might already think the vaccine is safe and effective to prevent infection before signing up to the study. Furthermore, socio-demographic data show that participants came from higher income households with parents who attained a high degree of education. Here, 67.5% of participants had a household income of USD 1500 a month, and 73.3% of parents.
