Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles.
I am sure I am not the only person who is asking why the Moderna vaccine which I understand is similar to the Pfizer vaccine has only been approved as 2 doses 28 days apart whereas the Pfizer vaccine has been approved as being effective after the first dose with a 12 week interval between doses, for which Pfizer have stated there is no current evidence.
