Article Title: How well do different COVID-19 vaccines protect against different viral variants? A systematic review and meta-analysis.
Article Snippet: The AstraZeneca Viral Vector Vaccine and the Johnson & Johnson Viral Vector Vaccine also demonstrated protection against the Alpha variant, with RR values of 0.29 (95% CI 0.22 to 0.38) and 0.25 (95% CI 0.15 to 0.42), respectively (Figure 4 B). .. While the Pfizer-BioNTech Nucleic Acid Vaccine, Clover Biopharmaceuticals Protein Subunit Vaccine, Johnson & Johnson Viral Vector Vaccine and Novavax COVID-19 Vaccine continued to show important protection against infection with the Beta vari- ant, this was not the case for AstraZeneca Viral Vector Vaccine (RR = 0.79; 95% CI 0.43 to 1.44) (Figure 4 C). ..
