The indirect effect of mRNA-based COVID-19 vaccination on unvaccinated household members.external icon Salo et al. medRxiv (May 29, 2021).
Key findings:
After 1 dose of mRNA vaccine, effectiveness increased over time for both vaccinated individuals and their unvaccinated spouses (Figure).
Among vaccinated individuals, the relative risk reduction was 26.8% (95% CI 7.5%-42.1%) 2 weeks later and 69.0% (95% CI 59.2%-76.3%) 10 weeks later.
Among unvaccinated spouses, the relative risk reduction was 8.7% (95% CI -28.9%-35.4%) 2 weeks later and 42.9% (95% CI 22.3%-58.1%) 10 weeks later.
Methods: Data from a mass vaccination program in Finland between December 2020 and March 24, 2021 looking at the effectiveness of mRNA-based COVID-19 vaccines in reducing the cumulative risk of infection among vaccinated healthcare workers (n = 95,138) and their unvaccinated spouses (n = 52,766).
Effectiveness estimates were reported by follow-up week after receiving the first dose. Limitations: The extent of contact of spouses with SARS-CoV-2-infected individuals is unclear.
Implications: mRNA-based vaccines not only prevent SARS-CoV-2 infections among vaccinated individuals but lead to a substantial reduction in infections among unvaccinated household members.

That’s good to know...I’ll make an appointment for my wife to take the jabs.
