Delaying second Covid-19 vaccine doses can help reduce deaths: Study

The US study, published in the BMJ British medical journal, used a simulation model based on a "real-world" sample of 100,000 US adults and ran a series of scenarios to forecast potentially infectious interactions under different conditions.

Giving a first dose of Covid-19 vaccine but delaying a second dose among people younger than 65 could lead to fewer people dying of the disease, but only if certain conditions are met, a predictive modelling study showed.
