Maternal worry of children contracting COVID-19 predicts vaccine uptake in young children in Vermont.

Background: Young children, 6 months to 4 years of age, were the last population for whom the COVID-19 vaccines became available and remain the group with the lowest uptake. Scarce information exists on drivers of vaccine uptake in young children. The relationship between parental perceived risk of infection and child COVID-19 vaccination is unknown. Objective: Examine the association between perceived risk of infection and early childhood vaccination. Methods: In June 2020, perinatal women in Vermont were enrolled in a longitudinal survey study assessing life changes during the pandemic. Surveys included worry of infection, Parents Attitude about Childhood Vaccines (PACV), intention to vaccinate children with the COVID-19 vaccine, and masking behaviors. Once vaccines became available, surveys also included child vaccination status. A demographic-adjusted stepwise logistic regression was conducted to assess the relationship of worry of infection and vaccine hesitancy on child vaccination status. Results: 85 women completed baseline and follow up surveys. Participants were highly adherent to adult COVID vaccines with 93 % at least partially vaccinated and only 3 % demonstrated general childhood vaccine hesitancy on the PACV. However, in this highly adherent population, only 61 % of young children are vaccinated. In univariate [OR = 7.35 95 % CI (2.70 to 20.02)] and demographic adjusted [OR = 6.03 95 % CI (1.30 to 27.90)] models, current worry about child infection was associated with higher odds of child vaccination. Previously established predictors, vaccine hesitancy [OR = 0.91 95 % CI (0.84 to 0.99)] and younger maternal age [OR = 1.33 95 % CI (1.07 to 1.65)] were again associated lower odds of child vaccination. Conclusion: Among vaccine adherent parents, worry of infection was a strong predictor of vaccine uptake. Continued efforts to articulate the potential morbidity of COVID in young children, along with established methods to address general vaccine hesitancy may aid in COVID vaccine uptake in this population.

COVID-19 infection and a repeated false positivity effect in HIV testing: A case report.

Several reports in the literature have described the association between SARS-CoV-2 infection and false positive HIV testing results. We present a case of a cisgender male who has sex with men with a false positive HIV test after fully recovering from COVID-19 14 days prior. Initial 4th generation HIV 1 and 2 antibody/antigen testing was positive twice, but confirmatory antibody testing was negative. HIV viral load was persistently undetectable. Most of the previously published case reports describe concurrent testing and positivity for HIV and COVID-19. Our report stands out due to the implication of a potentially prolonged association that could persist for several weeks.
