Suthar and his research team at Emoryâs Vaccine Center found that the immunity from the Moderna COVID-19 vaccine dips after six months, but not so much so that the vaccine becomes ineffective. Both Moderna and Pfizer's COVID-19 vaccines have a high efficacy rate against the South African virus variant, according to health experts. That said, Moderna said in February that it is currently starting trials for a third COVID-19 vaccine that would protect against the variant discovered in South Africa, as I wrote for the Deseret News.

Moderna's research letter in the NEJM on its COVID-19 vaccine showed a sixfold drop in antibody levels against the South Africa strain, the newspaper said. The company is also advancing an emerging variant booster candidate (mRNA-1273.351) against the variant first identified in South Africa. The UK Government has purchased 17 million doses of the Moderna vaccine â enough to vaccinate 8.5 million people, but the first doses are not expected to arrive in the country until the spring.
