After-school programs provide a range of support for students. During school closures due to the COVID-19 pandemic, many after-school programs were also forced to close or to find new ways to provide services to youth, such as through virtual after-school programming. We surveyed 244 youth who participated in virtual after-school programs about their access to virtual programming as well as their experiences. We considered their pre-closure experiences as well. We also surveyed 8 program directors of after-school programs who were providing virtual programming. We found that Internet access hindered the ability of more than 1 in 4 students to access the programs. Pre-closure program experiences, including ongoing relationships with program staff and positive peer relationships contributed to more positive experiences with virtual programming. Whenever students were able to access the programs, they generally reported positive experiences. This work has implications for after-school program providers, parents, and policymakers.

One hundred and twenty healthy volunteers were recruited for a study to evaluate the reactogenicity and serological response of differing doses of the 1986/87 World Health Organization-recommended influenza viral strains. Each vaccine was prepared by Institut Merieux and contained A/Mississippi/1/85, A/Chile/1/83 and B/Ann Arbor/1/86. One vaccine was formulated as a 10/10/10 micrograms HA and the other as a 15/10/15 micrograms HA. No significant advantage could be found with the 15/10/15 micrograms HA combination and it was recommended, therefore, that a 10/10/10 micrograms HA formulation was to be preferred. This vaccine demonstrated a minimal cross-sensitivity to the A/Singapore/6/86 influenza strain. In view of the prevalence of the A/Singapore strain, a second study was subsequently undertaken with a monovalent A/Singapore/6/86-like vaccine in a further 62 volunteers. This demonstrated an overall sero-conversion rate of 90%. Local side-effects with both vaccines were lower than in a similar study in 1984 and this may reflect a reduction in endotoxin levels achieved by a minor modification in the manufacturing technique. These studies confirmed the efficacy of a trivalent A/Mississippi, A/Chile, B/Ann Arbor influenza vaccine and the efficacy of, and necessity for, an additional A/Singapore vaccine.
