Duration of protection of CoronaVac plus heterologous BNT162b2 booster in the Omicron period in Brazil

Primary CoronaVac vaccination followed by a BNT162b2 booster dose confers protection against some SARS-CoV-2 variants but its effectiveness against Omicron is unknown. Here, the authors show that this combination confers a high level of protection against severe outcomes for up to 120 days, with evidence of waning for those aged 80 or older.

Vaccine effectiveness of CoronaVac against COVID-19 among children in Brazil during the Omicron period

There is limited evidence of the effectiveness of the CoronaVac vaccine for children against the Omicron SARS-CoV-2 variant. Here, the authors use data from Brazil for children aged 6–11 years and estimate effectiveness of 40% against infection and 59% against severe disease at least two weeks after the second dose.

Vaccine effectiveness of heterologous CoronaVac plus BNT162b2 in Brazil

A test-negative case–control analysis of data from Brazil shows that vaccine effectiveness against SARS-CoV-2 infection and severe COVID-19 outcomes declines after two doses of CoronaVac but increases after a booster dose of the BNT162b2 vaccine.
