San Mateo County health officials have urged residents six months or older to get the seasonal flu vaccine as well as the COVID-19 vaccine, which has been updated and was approved this week by the U.S. Centers for Disease Control and Prevention (CDC).
Fall and winter mark the traditional flu season, as more indoor activities take place and holiday travel increases. However, COVID-19 is more transmissible in confined spaces, so there is a higher risk of respiratory viruses during this period.
