A vaccine booster is meant to increase levels of immune responses after they have naturally waned. Just like the weather, viruses are constantly changing, and the COVID-19 virus is no exception. According to the CDC, viruses change constantly through mutation and sometimes these mutations result in new variants of the virus.
New variants of the virus are expected to occur and will continue to emerge. Currently, there are two main variants of concern, Omicron and Delta, both of which spread more easily than other variants.
Because of the changing variants, public health experts started seeing reduced protection over time against infection or severe illness. Clinical trial data shows a vaccine booster increases the immune response and helps prevent severe disease or hospitalization.
Getting boosted is the best way to slow the spread of COVID-19 and to prevent infection by Delta, Omicron or other variants. Schedule your appointment today at any of our pharmacies or health department.
