ზუსტად ერთი წლის წინ ვთქვი, რომ საქართველოში ჩინური ვაქცინების გამოყენება უნდა შეჩერდეს-მეთქი, ვინაიდან უკვე არსებობს არაერთი კვლევა, რომ ეს ვაქცინები დაბალეფექტურია, განსაკუთრებით, კოვიდის ახალი შტამების წინააღმდეგ (დელტა/ომიკრონი).
სამწუხაროდ, დღესაც ამ ვაქცინებს იყენებენ საქართველოში… ვადა არ გასდის? თუ უვადოა? წყაროები მითითებულია… ჯანმრთელობას გისურვებთ …

Findings: A total of 1800 individuals who have received two doses of BBIBP-CorV were enrolled, of which 899 participants received a heterologous boost of NVSI-06-07 and 901 received a homologous boost for comparison The heterologous BBIBP-CorV/NVSI-06-07 prime-boosting vaccination may be valuable in preventing the pandemic of Omicron. The optimal booster strategy was the heterologous boost with NVSI-06-07 over 6 months after a priming with two doses of BBIBP-CorV.

BEIJING, Jan 7 (Reuters) – A protein-based COVID-19 vaccine made by Sinopharm, when given as a booster after two doses of an earlier shot from the Chinese firm, elicited a stronger antibody response against the Omicron variant than a third dose of the original, a study showed.
-
An earlier study showed a BBIBP-CorV booster had weaker neutralisation against Omicron than against an older coronavirus strain from the central Chinese city of Wuhan
-
inopharm’s NVSI-06-07 protein-based vaccine, approved for emergency use as a booster in the United Arab Emirates in December, adopts a different technology than the BBIBP-CorV shot that contains an inactivated form of the coronavirus.
-
Among 192 healthy adults vaccinated with two BBIBP-CorV doses for six months or longer, the neutralising antibody level against Omicron in those later given a NVSI-06-07 booster was “significantly higher” than that in those who received a BBIBP-CorV third dose, researchers said in a paper.
-
The authors of the study, which was published on Tuesday and had not been peer reviewed, included researchers from Sinopharm’s units and Sheikh Khalifa Medical City in Abu Dhabi. They cautioned that it remained unclear for how long Sinopharm’s NVSI-06-07 booster’s effect would last. Sinopharm’s NVSI-06-07 protein-based vaccine adopts a different technology than the BBIBP-CorV shot that contains an inactivated form of the coronavirus.

BEIJING, Dec 20 (Reuters) – A COVID-19 booster shot produced by China’s Sinopharm had “significantly lower” neutralising activity against the Omicron variant, Chinese researchers said in a paper, although they added the vaccine’s efficacy against Omicron remained unclear.

The neutralising antibody activity of a Sinopharm BBIBP-CorV booster against Omicron showed a 20.1-fold reduction, compared with its activity against a Wuhan strain, according to the paper published on Saturday.
