Scotland’s Vaccine Rollout Suggests Delaying the 2nd COVID-19 Shot Is a Bad Idea

February 26, 2021

(Business Insider) – The UK’s strategy of delaying second coronavirus vaccine doses up to 12 weeks to give more people a first shot may carry serious risk. On Monday, Scottish researchers released data from their vaccination campaign, including more than 1 million people who’ve been immunized, that suggests protection from a single dose peaks and then declines after about five weeks. The Scottish data hasn’t been published in a medical journal or reviewed by independent scientists. The results were posted as a preprint on Monday.
