Vaccine effectiveness & Omicron
Expert studies have shown that the risk of severe illness from Covid-19 is reduced by 90 percent or more among people who are fully vaccinated.
While there are breakthrough cases of Covid among people who are vaccinated, they are rare.
In the event of a breakthrough case, victims are highly unlikely to be hospitalized with severe or deadly symptoms from the virus.
Health officials have advised that the Omicron variant is more infectious and could lead to further breakthrough cases.
Yet the spread can be offset by all vaccinated Americans receiving a booster shot.
Current vaccines are expected to protect against severe illness, hospitalizations, and deaths due to infection with the Omicron variant.
With other variants, like Delta, vaccines have remained effective at preventing severe illness, hospitalizations, and death.
Studies have also shown that side effects from the vaccine are extremely rare.
