“All indications are that Omicron can spread rapidly among both vaccinated and unvaccinated individuals,” said Ferrer. “Early data suggests that many of those fully vaccinated do not experience serious illness, reminding us that one of the most critical steps to take right now is to urgently get vaccinated if not yet protected or boosted as soon as you are due for the additional dose.”
