Vaccinating premature babies is always fraught with danger. Their bodies are not mature enough to develop 'proper' antibodies - even if you accept that antibodies are an indication of immunity (which I don't). But study after study has linked vaccination according to birth date to be dangerous as opposed to vaccination according to gestational age.
This story is so sad because not only were these premature tiny twins vaccinated according to their birth date (and one of them had needed resuscitation at birth!), but they were given NINE VACCINES in one day and one of them subsequently became ill and died.
It is not surprising that she died. It is also not surprising that doctors deny any involvement in her death.
Accountability for its errors has never been a strong point of Western medicine.
