Early data suggests three doses of Pfizer and BioNTech's COVID-19 vaccine provides protection against the new Omicron variant, the companies say.

Pfizer and BioNTech announced Wednesday that a third dose of its COVID-19 vaccine offers a similar amount of protection against the new Omicron variant as two doses of the vaccine does against the original strain of the coronavirus, NBC News reports. The companies also said, however, that preliminary studies indicate two doses "may not be sufficient to protect against infection with the Omicron variant," and a third dose provides "more robust" protection.
