(Reuters) -The U.S. Centers for Disease Control and Prevention's outside expert panel will convene on Tuesday after a nearly two-month delay and expects to review guidelines for several vaccines including recommendations for the next generation of COVID-19 shots. The two-day meeting of the Advisory Committee on Immunization Practices also plans to discuss the ongoing U.S. measles outbreak that has infected over 700 people this year, mostly among unvaccinated people in Texas and New Mexico. The meeting was abruptly delayed in February just days after Robert F. Kennedy Jr., a long-time vaccine skeptic, became head of the U.S. Department of Health and Human Services.
