1/5 ÚLTIMO MOMENTO: #SputnikV muestra una fuerte protección contra #Ómicron, más del doble de actividad neutralizante frente a Pfizer, en un estudio independiente realizado por el Instituto Spallanzani con sede en la UE @INMISpallanzani
LEER 👇
sputnikvaccine.com/esp/newsroom/p…
2/5 El estudio realizado en Inst. Spallanzani, en Italia, en muestras de suero comparables, muestra que Sputnik V induce anticuerpos neutralizantes 2,1 veces más altos que 2 dosis de Pfizer en total, 2,6 veces más alto 3 meses después de la vacunación

3/5 Gran rendimiento de Sputnik por:
• Amplio conjunto de anticuerpos frente a estructura estabilizada con prolina menos flexible de Pfizer que produce anticuerpos contra partes mutadas del virus
• 2 dosis distintas
• Vectores adenovirales imitan mejor la infección natural
4/5 Estudio de Spallanzani: entre el cuartil superior de personas con anticuerpos IgG específicos de RBD altos, el 100 % de los vacunados con #SputnikV pudieron neutralizar la variante Ómicron en comparación con el 83,3 % de las personas vacunadas con #Pfizer.
5/5 Según los datos del Inst. Spallanzani y los resultados de otros estudios, el refuerzo combinado con Sputnik Light es la mejor solución para aumentar la eficacia de otras vacunas y extender el período de protección contra #Ómicron

2/5 Study, conducted in equal lab conditions in Spallanzani Inst in Italy on comparable sera samples, shows Sputnik V induces 2.1x higher virus neutralizing antibodies titers than 2 doses of #Pfizer jab in total, 2.6x higher 3 months after vaccination

3/5 Reasons for Sputnik superb Omicron performance:

• Wide pool of antibodies vs Pfizer’s less flexible proline-stabilized structure producing antibodies to most mutated virus part

• Mix&match scheme with 2 different shots

• Adenoviral vectors better mimic natural infection

In recognition of quickly waning Pfizer vaccine efficacy US FDA recommends reducing interval for Pfizer booster shot from 6 months to 5 months. Instead, booster by other vaccines is needed to lengthen Pfizer vaccine protection particularly against #Omicron

Gamaleya Institute: “Russian Ministry of Health recommends Sputnik Light booster 6 months after vaccination to increase protection against #Omicron and other mutations.” Sputnik vaccines showed high level of virus neutralizing antibodies and T cells against #Omicron Image
Sputnik Light is a universal booster to other vaccines for fastest, strongest and longest protection against #Omicron and other mutations.
