Heterologous Oxford And Pfizer Covid-19 Vaccines Induce Strong Immune Response And T Cell Reactivity Against Multiple SARS-CoV-2 Variants

▫️Researchers From Germany Recently Analyzed A Cohort of 26 Individuals In The Age Range of 25 to 46 (Median 30.5) Years Who Had Received A ChAdOx1 nCoV-19 (Vaxzevria, Oxford-AstraZeneca) Prime Vaccine Followed by A BNT162b2 (Comirnaty, BioNTech-Pfizer) Boost Vaccine After A 56-day Interval Due To Changing Vaccine Recommendations In Germany.
▫️There Were 16 Females And 10 Males In The Cohort, And They Were Assessed For Immune Responses, Reactogenicity, And T Cell Reactivity. This Study is Published on The medRxiv PrePrint Server.
▫️The Results Show That, Neutralizing Activity Against The UK Variant B.1.1.7 In Individuals Receiving Heterologous Vaccination Was 3.9-Fold Greater Than That In Individuals Receiving Homologous BNT162b2 Vaccination.
▫️Neutralizing Activity Was 2-Fold Reduced for The South African Variant B.1.351 And Was Similar for The B.1.617 Variant.
▫️To Summarize, The Heterologous ChAdOx1 nCoV-19 - BNT162b2 Prime-Boost Vaccination Regimen Did Not Cause Serious Adverse Events And Elicited A Potent Humoral Immune Response And T Cell Reactivity.

UK Study Finds Vaccines Offer High Protection Against Hospitalisation from Delta Variant

▫️Covid-19 Vaccines Made by Pfizer And AstraZeneca Offer High Protection of More Than 90% Against Hospitalisation from The Delta Coronavirus Variant, A New Analysis by Public Health England (PHE) Showed on Monday.
▫️PHE Said That The Pfizer-BionTech Covid-19 Vaccine Was 96% Effective Against Hospitalisation from The Delta Variant After Two doses, While AstraZeneca's Offered 92% Protection Against Hospitalisation by Delta.
▫️PHE Said That Those Levels Of Protection Were Comparable To That Against The Alpha Variant, First Identified In Kent, Southeast England.
▫️The Analysis Adds To Evidence That, Although The Delta Variant Reduces The Effectiveness of Vaccines Against Symptomatic Infection, Two doses of Covid-19 Vaccine Still Protect Against Severe Disease.
▫️The PHE Findings Follow A Scottish Study Which Showed That Two doses of A Covid-19 Vaccine Among People Who Tested Positive Cut Their Risk of Hospitalisation by 70%, Although There Were Not Enough Hospital Admissions Reported To Compare The Vaccines.
