The health ministry stated the suspension will be effective until the results of an investigation of the four deaths by a group comprising medical experts, expected to be released on 8 March, reports The Wall Street Journal.
Pfizer’s Prevnar is a pneumococcal conjugate vaccine that protects against a bacterium that causes meningitis, while ActHIB is a type b Haemophilus influenzae vaccine that protects against a bacterium that causes meningitis and pneumonia.
Pfizer told The Wall Street Journal that the health ministry has raised certain questions and the company is in the process of preparing responses. As per the company’s evaluation, the vaccine doses administered in the four cases were from three separate lots.
Sanofi stated that it is awaiting the findings of the expert panel and is not planning to recall ActHIB at present.
