Out of an abundance of caution, the County of Ventura is following the recommendation of the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) to pause the use of Johnson & Johnson vaccine after reports that 6 women between the ages of 18 and 48 developed unusual types of blood clots 6 to 13 days after receiving the vaccine. This pause will last until the FDA and CDC complete their review, which is expected to take several days.
