A year to vaccinate the high risk group sounds way overblown. Maybe it's taking into account people who won't accept it right away? The vaccine is being rationed because of high demand. The moment demand drops, it no longer makes sense to ration it the same way. Also keep in mind that distribution speed will increase over time as procedures and protocols are put in place and learned by everyone. I suspect the majority of people who want to be vaccinated in europe will have their shot by september 2021. This is all off napkin math though.
