WASHINGTON (CNN) – “Save our children!” The cries of the millions of Americans who are concerned about vaccines as the Centers for Disease Control and Prevention prepares to announce its evaluation of the 2018 vaccine safety report have reached Joe Biden’s home, right in the heart of his city.
Activists with the Center for Disease Control and Prevention’s Advisory Committee on Immunization Practices protested his chief of staff during one of his Washington home runs Sunday, September 29. Their signs said things like “Dr. Biden: You’ve got to vaccinate,” and “CDA 574: Our 574 is not a big number.”
The protest is the culmination of two years of mounting opposition from anti-vaccination activists to the CDC’s suggestion that Americans over age 18 should get their children vaccinated against hepatitis B. The 11% of Americans without a child vaccinated compared with the 88% of children in the United States who are vaccinated is a big risk for outbreak of the virus.
The hepatitis B vaccine — which contains thimerosal — is included in childhood vaccines, but has also been available off-label for adults. They include people who were over 18 years old when they got the original thimerosal-containing vaccine, which some believe resulted in immune system defects, according to the protest.
The protesters want to see thimerosal removed entirely from childhood vaccines and a vaccine to prevent whooping cough, which affects both boys and girls, because the CDC says that the rate of that disease among adolescents has skyrocketed in recent years.
“The CDC recommends everyone at least age 11 and 12 be vaccinated against whooping cough, which can lead to permanent respiratory infections, pneumonia and death,” the group said in a statement. “But there is growing opposition to vaccinating adolescents, as many families believe that childhood vaccines are too strong and that autism is a ‘myth.’ “
The group of protesters showed up at Carino Golf Course, and asked several of Biden’s staff to come with them. It was also able to shout at 10 of Biden’s neighbors.
“This is a public health emergency,” said one protester, Karon Maitland. “The people we want to get vaccinated are low-income or teens living in communities. We want them to know that we’re not going away and they need to do something about it.”
As he played with the neighbors, the protesters yelled out Biden’s name and told the family if they didn’t want to come to the protest “to don’t feel ashamed.”
CNN reached out to Biden’s office about the protests, but could not immediately obtain a response.
