Covid-19: Moderna plans booster doses to counter variants

Moderna has announced that it is developing two new booster approaches to the vaccine schedule to address emerging variants of covid-19 after studies showed that its vaccine had a reduced level of neutralising titres to the South African variant.

SPS commentary:

In the UK variant, neutralising antibody titres were high and were generally consistent with the neutralising titres seen with prior variants.
