Background The relationship between postvaccination symptoms and strength of antibody
responses is unclear. The goal of this study was to determine whether adverse effects …

Adverse reactions after vaccination with COVID-19 mRNA vaccines are common; however,
the association between adverse reactions and humoral responses is uncertain. To …

Objectives To assess the antibody response to BNT162b2 mRNA COVID-19 vaccine in a
cohort of health-care workers (HCW), comparing individuals with previous severe acute …

Objectives: The BNT162b2 mRNA COVID-19 vaccine has been found to be highly effective
in preventing COVID-19 but is associated with increased reactogenicity. We aimed to …

Background Safe and effective vaccines against COVID-19 are critical for preventing the
spread of SARS-CoV-2, but little is known about the humoral immune response more than 9 …

Objectives This study aimed to determine antibody responses in healthcare workers who
receive the BNT162b2 mRNA COVID-19 vaccine and identify factors that predict the …

Background SARS-CoV-2 vaccines are an invaluable resource against COVID-19. Current
vaccine shortage makes it necessary to prioritize distribution to the most appropriate …

Abstract Background Since July 13, 2021, a third SARS-CoV-2 vaccine BNT162b2 was
approved in Israel to immunocompromised and seniors 60 years of age or older. We aimed …

Although antibody levels progressively decrease following SARS-CoV-2 infection, the
immune memory persists for months. Thus, individuals who naturally contracted SARS-CoV …

Background: The effect of post-vaccination adverse events on immunogenicity is unknown.
We aimed to explore relationship between post-vaccination adverse reactions and antibody …
