@JamesConran1 @n_hold @wsbgnl @BillHanage Before near-universal immunity (of some degree), it was easier to measure, but Alpha was probably the last variant where it was easy to measure transmission advantage. One animal study (w/non-immune population) suggested Delta more transmissible than Omicron.
