The Oakland Coliseum, home of MLB's Oakland A's, has been used as a vaccination site. Health officials believe as many as 6,300 people visiting the Coliseum site may have received less vaccine in their shots than they were supposed to, but the weaker dose was still considered strong enough to defend against the virus, the officials told FOX 2. After those recipients receive their second vaccine shot, that will make up for the weaker first shot, they said. FOX 2 first learned of the problem with the dosages when two paramedics who requested anonymity contacted the station. The error was attributed to Coliseum vaccination staff being provided a different type of syringe that wasn’t fully pushing out the vaccine into people’s arms, according to FOX 2.
