People are confused about why the second vaccine is being delayed. The theory is that you potentially could gain some efficacy by waiting longer. But there's a wrinkle depending on which of the vaccines you're talking about. And i think the debate really is just that we don't have hard evidence to show that it's still going to be as effective.
The science behind how and when to give vaccines doses.
As vaccines are rolled out, massive logistical challenges are leading scientists and policymakers to consider alternative dosing strategies.
But what does the science say? In this week’s episode of Coronapod, we discuss mixing and matching vaccines and lengthening the time between doses. Approaches like these could ease logistical concerns, but we ask what's known about their impact on vaccine efficacy – what is the science behind the decisions, and could they actually boost immune responses?
