Reduced immunogenicity of the mRNA vaccine BNT162b2 in patients with IPF

ABSTRACT

The emergence and spread of 2019 coronavirus disease (COVID-19) are causing a growing global public health crisis. Despite advances in treatment, vaccination remains the best way to contain the pandemic [1]. Vaccines are currently available by means of conditional marketing approval, full approval and emergency use authorization pathways [2]. Evidence suggest that immunocompromised individuals including solid organ transplants recipients and patients under immunosuppressive treatment may have increased mortality from SARS-CoV-2 infection despite double dose messenger RNA (mRNA) vaccine regimens [3]. This is partially attributed to blunted immune responses to vaccination since only 38–54% of kidney and liver transplant recipients developed detectable SARS-CoV-2 antibodies following the second dose of mRNA vaccines [3, 4].
