Will vaccines work against the new virus?

Most experts think the newly developed vaccines will still work against the novel U.K. variant. When vaccines stimulate the immune system, the body builds an arsenal of cells to bind to many different parts of the virus. Mutations in a handful of spots will likely not be enough to make the vaccine less effective, according to the CDC.

Given that 99% of the proteins on the new variant are identical to the strain the Pfizer-BioNtech mRNA vaccine targets (the Moderna vaccine is very similar), it is highly likely that the vaccine will work, BioNTech CEO Uğur Şahin said at a news briefing.

It's possible that over time a variant could emerge that will evade some of our vaccines, similar to how the flu vaccine needs to be updated every year. However, the new mRNA vaccines could be updated to reflect new mutations in about six weeks, Şahin told the Financial Times.
