CDC vaccine advisers to revisit Johnson & Johnson Covid-19 vaccine recommendation
"The source said because of TTS, and because the vaccine is not as effective against Covid-19 as Pfizer or Moderna vaccines, "J&J hasn't lived up to its billing as 'one and done.'"
"Thrombosis and thrombocytopenia syndrome has been linked to both the Johnson & Johnson vaccine and AstraZeneca vaccine, which is
not available in the United States, but is widely used around the world and uses similar technology."
"The FDA said Tuesday that cases of TTS after the Johnson & Johnson vaccine "have been reported in males and females 18 years of age and older, with the highest reporting rate of approximately 1 (one) case per 100,000 doses administered in females 30-49 years of age; overall, approximately 1 out of 7 cases has been fatal," the agency added."
