Health officials fear 4th wave of COVID-19 cases due to spring breakers, variants

Health officials say they are worried about a potential fourth wave of COVID-19 due to people traveling for spring break.
Spring breakers have descended on Florida en masse and the beaches and restaurants have filled up to the point that a state of emergency was declared in Miami and are instituting a curfew.
Health officials say they're afraid of these people getting infecting and then flying home.
That's what's happened in many parts of Europe, where they are going through lockdowns again.
One advantage the U.S. has over Europe is that the U.S. is ahead in coronavirus vaccinations.
The CDC says more than 121 million doses have been administered in the U.S. and about 43 million people have been fully vaccinated.
According to local infectious disease specialist Dr. Harish Moorjani, the U.S. still needs to get that number up, especially with the variants spreading so quickly.
Right now about 25% of the U.S. population has had at least one shot. Health experts believe we need to be closer to 80% fully vaccinated before we reach herd immunity.
