Objectives: There is conflicting evidence as to whether the combined administration of two vaccines can lead to poorer immunogenicity and reactogenicity. The co-administration of the Omicron-adapted COVID-19 vaccine from Novavax (NVX-CoV2601) and a 20-valent pneumococcal conjugate vaccine (PCV20) has not been previously investigated.
Methods: In this randomised, double-blind, placebo-controlled, non-inferiority trial, immunocompetent participants aged ≥60 years were randomised in a 1:1:1:1 ratio to four groups: NVX-CoV2601 plus PCV20 (combination group); NVX-CoV2601 plus placebo (NVX-only group); PCV20 plus placebo (PCV20-only group); or placebo plus placebo (placebo group).

Despite high initial vaccination rates, Spain's current COVID-19 vaccination coverage in recommended groups does not meet WHO targets. For the upcoming season, challenges include revising vaccination age, updating risk groups, and unifying criteria with flu vaccine co-administration. European Commission's advance purchase agreements limit access to certain vaccines, and the need for vaccines effective against current variants adds administrative complexities.

While marked differences exist between influenza virus, respiratory syncytial virus (RSV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), there is substantial overlap in the vulnerability of populations most at risk for severe disease following infection, chief among them being advanced age, multiple comorbidities, and immunocompromise. Vaccination is an established and effective preventative strategy to protect against respiratory viral infections (RVIs), reducing morbidity and mortality, minimizing the potential for long-term complications, and mitigating exacerbation of existing health conditions. Despite the demonstrated benefits of immunization throughout the life course and recommendations by health authorities, coverage rates of at-risk populations against vaccine-preventable diseases remain suboptimal and vary considerably by country and demographic strata.

Background: Despite high COVID-19 vaccine coverage in Canada, vaccine acceptance and preferred delivery among newcomers, racialized persons, and those who primarily speak minority languages are not well understood. This national study explores COVID-19 vaccine acceptance, access to vaccines, and delivery preferences among ethnoculturally diverse population groups.
Methods: We conducted two national cross-sectional surveys during the pandemic (Dec 2020 and Oct-Nov 2021).
