Two Doses Of Pfizer Vaccine Induce Good Antibody Response Against SARS-CoV-2 Variants

Two doses of the Pfizer COVID-19 vaccine induce a “very good” antibody response against the SARS-CoV-2 variants, according to a study on 180 health care workers in Finland. The research, published in the journal Nature Communications on June 28, found that the immune response was as strong against the Alpha variant first identified in the UK, as against the original virus found in Wuhan, China in 2019. The immune response was somewhat decreased against the Beta variant first found in South Africa, but the vaccine generated neutralizing antibodies that give relatively good protection against the variant. A neutralizing antibody is responsible for defending cells from pathogens. The researchers, including those from the University of Turku and University of Helsinki, studied the immune response induced by the coronavirus vaccinations, which started in Finland in December last year. They analyzed vaccine responses in 180 health care…
