Timothy Harrington discusses his inured son with RFK Jr. Timothy's 21-year-old son suffered severe heart inflammation after receiving his second shot. Justin Harrington, whose school required him to get it in order to attend classes in the fall, experienced flu-like symptoms followed by heart pain within eight to 12 hours of receiving the vaccine. Justin’s father, Timothy Harrington, said his son felt different after the second shot. “Every time his heart beat it hurt and he felt pressure,” Harrington said. “Then he developed heart pain down both arms.”
