President Joe Biden on Monday called the coronavirus variant omicron a "cause for concern, not a cause for panic" as he urged Americans to get vaccinated against COVID-19. Biden plans to outline Thursday a "detailed strategy" on how the administration will fight COVID-19 in the coming winter. "Not with shutdowns or lockdowns," he said. "But with more widespread vaccinations, boosters, testing and more." Biden's remarks came on the day travel restrictions from South Africa and seven other countries begin. Biden announced the travel rules Friday, days after the variant was first reported to the World Health Organization by South Africa. WHO has urged countries not to impose flight bans on southern African nations. “Travel restrictions may play a role in slightly reducing the spread of COVID-19 but place a heavy burden on lives and livelihoods,” the organization said in a statement Sunday. But Biden said the restrictions are necessary to give Americans more time to get their first vaccines or to get booster shots. "It gives us time to take more action, to move quicker, to make sure people understand you have to get the vaccine," he said. Tap the link in bio to read the full story.
