The BA.5 variant is continuing to grow in the U.S., almost entirely pushing out other forms of the virus. Some experts fear that the highly transmissible variant could fuel yet another summer Covid surge - a third in as many years - while others think there is enough immunity in the population to continue on life as normal.The strain now makes up 78 percent of sequenced COVID-19 cases, according to data revealed Tuesday by the Centers for Disease Control and Prevention (). It is a rapid increase from the 55 percent of cases it made up only two weeks ago.Federal officials' response to the virus thus far has focused on the rollout of vaccines, hoping that repeated shots could shore up protection long-term and reduce its ability to cause severe hospitalization or death. Another vaccine will soon join the lineup as well, with the CDC officially recommending the vaccine to U.S. adults this week.
