Authors: David Axe Updated Oct. 16, 2022 A new subvariant of the novel-coronavirus called XBB dramatically announced itself earlier this week, in Singapore. New COVID-19 cases more than doubled in a day, from 4,700 on Monday to 11,700 on Tuesday—and XBB is almost certainly why. The same subvariant just appeared in Hong Kong, too. A highly mutated descendant of the Omicron […]

Authors: Kenji Yamamoto  Virology Journal volume 19, Article number: 100 (2022)  Abstract Recently, The Lancet published a study on the effectiveness of COVID-19 vaccines and the waning of immunity with time. The study showed that immune function among vaccinated individuals 8 months after the administration of two doses of COVID-19 vaccine was lower than that among the unvaccinated individuals. According to European Medicines […]
