The D614G mutation emerged in eastern China early in the pandemic and then quickly spread around the world, displacing other coronaviruses that did not have the mutation.

The D614G mutation is thought to make the coronavirus more infectious, but it does not appear to make the disease more severe or help the virus escape vaccines.

The N501Y mutation arose independently in several variants of concern, including the B.1.1.7, B.1.351 and P.1 lineages.

The mutation is near the tip of the coronavirus spike, where it seems to change the shape of the protein to be a tighter fit with human cells.

The E484K mutation arose independently in multiple lineages, including B.1.351 and P.1. Scientists are also concerned that the mutation was recently found in some samples from the B.1.1.7 lineage from Britain. …
The mutation occurs near the top of the coronavirus spike, where it alters the shape of the protein. This change may help the spikes evade some types of coronavirus antibodies.

Interim Clinical Considerations for Use of mRNA COVID-19 Vaccines | CDC

February 5, 2021

QT:{{”

Persons should not be scheduled to receive the second dose earlier than recommended (i.e., 3 weeks [Pfizer-BioNTech] or 1 month [Moderna]). However, second doses administered within a grace period of 4 days earlier than the recommended date for the second dose are still considered valid. Doses inadvertently administered earlier than the grace period should not be repeated.

The second dose should be administered as close to the recommended interval as possible. However, if it is not feasible to adhere to the recommended interval, the second dose of Pfizer-BioNTech and Moderna COVID-19 vaccines may be scheduled for administration up to 6 weeks (42 days) after the first dose. There are currently limited data on efficacy of mRNA COVID-19 vaccines administered beyond this window. If the second dose is administered beyond these intervals, there is no need to restart the series.

Evidence Builds That an Early Mutation Made the Pandemic Harder to Stop

Scientists were initially skeptical that a mutation made the coronavirus more contagious. But new research has changed many of their minds.

How COVID unlocked the power of RNA vaccines

.@ElieDolgin’s great feature on the development of new mRNA vaccines highlights how important breakthroughs in lipid nanoparticles were. Interesting that a lot of the key research appears to be funded by @Darpa.
