COVID-19 after Vaccination
COVID-19 vaccines continue to be highly effective at protecting people against severe illness and death, including disease caused by Delta and other variants circulating in Clark County. Getting vaccinated is the best way to slow the spread of COVID-19 and prevent more variants from developing. No vaccine is 100 percent effective, and breakthrough infections among vaccinated people are expected. Because vaccines are not 100 percent effective, as the number of people who are fully vaccinated goes up, the number of breakthrough cases will also increase.
