I include in the Record an article from the University of California San Francisco regarding COVID-19 vaccines reducing transmission. [From the University of California San Francisco, Jan. 2, 2023] Covid-19 Vaccines, Prior Infection Reduce Transmission of Omicron (By Laura Kurtzman) Vaccination and boosting, especially when recent, helped to limit the spread of COVID-19 in California prisons during the first Omicron wave, according to an analysis by researchers at UC San Francisco that examined transmission between people living in the same cell. The study demonstrates the benefits of vaccination and boosting, even in settings where many people are still getting infected, in reducing transmission. And it shows the cumulative effects from boosting and the additional protection that vaccination gives to those who were previously infected. The likelihood of transmission fell by 11% for each additional dose. vaccines reduce risk of serious illness from omicron infection In dense populations such as prisons, vaccines were shown to significantly reduce the risk of hospitalization and death from Omicron infections. Of over 20,000 confirmed Omicron infections in California prisons, there were 31 hospitalizations and no deaths attributed to COVID-19 infection. Vaccinated residents with breakthrough infections were significantly less likely to transmit them: 28% versus 36% for those who were unvaccinated.…
