CDC urges Americans to embrace mRNA vaccinesSee also:
The US health agency has recommended that people seeking vaccination for Covid-19 receive Pfizer or Moderna mRNA-based shots rather than the Johnson & Johnson vaccine, due to the risk of blood clots.
The Centers for Disease Control and Prevention (CDC) backed the recommendation of its advisory panel to designate the mRNA-based Covid-19 vaccines from Moderna and Pfizer/BioNTech the "preferred" vaccination option, citing newly-released data on the incidence of a severe but rare blood clot disorder in the adenovirus-based shot from Johnson & Johnson.
The drug behemoth has insisted that the benefits of its shot outweigh the risk of blood clots, and a company representative argued that while the maximum protection delivered by the vaccine comes later than that delivered by the mRNA shots, it also lasts longer.
