COVID-19-mRNA vaccine induces good immune response against coronavirus variants

(University of Turku) A new Finnish study shows that 180 health care workers who had received two doses of the Pfizer and Biontech vaccine have very good antibody responses against the SARS-CoV-2 virus. The immune response was as strong against the alpha variant (formerly the UK variant) but was somewhat decreased against the beta variant (formerly the South Africa variant).
