It was not the vaccines that caused the deaths of two babies and the hospitalization of 29 more in Chiapas last Friday, says the chief of the Social Security Institute, IMSS.
José Antonio González Anaya said tests have revealed the vaccines that were administered to 52 infants in the village of La Pimienta were not defective. The evidence, he said, points instead to an error in their handling.
“What we know is that at some point in the process the vaccine became contaminated. We don’t know the source, it could be anything.”
González Anaya said tests conducted on the surviving children, 14 of whom are still in hospital in Tuxtla Gutiérrez and four of those in serious condition, revealed the presence of bacteria. “This means there was external contamination,” he said, which could have occurred at the time of preparing the needles.
The investigation will continue in order to determine where that contamination came from. The institute, meanwhile, will strengthen its protocols in the vaccination program.
Medical personnel administered vaccines for tuberculosis, rotavirus and Hepatitis B in the Chiapas mining town on Friday morning. By nightfall, two had died.
