Summary

New Covid-19 variants have emerged, including B.1.526 in New York, which contains a mutation that may allow the virus to escape some immune responses. Vaccines developed against the original virus have been found to be less effective against some variants, such as B.1.351. Several vaccines have been approved or rolled out, including those from Pfizer, Oxford-AstraZeneca, Moderna, and others, with varying levels of effectiveness against symptomatic disease and safety profiles. Some manufacturers are updating their vaccines to target new variants. The rollout of vaccines is ongoing, with varying success in different countries, including Israel, where a study showed a 94% reduction in symptomatic cases with the Pfizer-BioNTech vaccine, and Germany, where there has been hesitancy to use the Oxford-AstraZeneca vaccine due to concerns over its effectiveness in older people.
