• The one-shot Johnson & Johnson COVID-19 vaccine is reported to have 66% efficacy, but the information from the company is "muddled" and the data have not been released yet.

• The Johnson & Johnson vaccine is not as effective against the South African variant. The company reported 72% vaccine efficacy in the United States but only 57% in South Africa.

• The Moderna and Pfizer vaccines probably would not show 95% efficacy against the South African variant either.

• Individuals will eventually need to get booster shots directed toward the new strains. But people should not wait for boosters; get the vaccine as soon as you can because some protection is better than none.

• The United Kingdom's more contagious B.1.1.7 strain is likely to become the dominant strain in the United States, unless vaccine distribution speeds up and people adhere more strictly to mask-wearing and social distancing.
