Why are COVID-19 vaccine booster shots necessary?
[Three illustrated doctors are next to a graph. The graph’s y axis is immunity and x axis is time. A line animates on the graph. It shows how a person’s level of immunity changes over time after getting a vaccine. The immunity starts high.]
Medical researchers have been monitoring how long protection from the COVID-19 vaccines remains high.
[We focus on the graph, as time continues, the line showing level of immunity starts to slowly decline.]
COVID-19 vaccines continue to be highly effective at reducing the risk of severe illness, hospitalization, and death ... but new data suggest that protection against infection decreases over time.
[An icon for a booster vaccine appears on the immunity line. The immunity line rises, returning to a high level of protection.]
Like many other routinely administered vaccines, COVID-19 vaccines need booster shots to maintain a higher level of protection over time.
[A new graph appears. The graph’s y axis is immunity and x axis is time. There is a line showing immunity over time and there is an icon indicating when a booster vaccine was given. The timing of booster vaccine sways forward and back. The immunity line on the graph is reacting, showing different outcomes of immunity depending on the timing. A green checkmark appears.]
The recommended timing is based on research showing when boosters are most effective at increasing immunity.
[The scene changes. A vaccine booster icon appears and a link is read aloud.]
