Brnabić: Rekla sam Kriznom štabu da ne verujem u mere, vakcina je jedini izlaz https://t.co/LXdfeyA2P6

Premijerka Ana Brnabić izjavila je da je epidemiološka situacija "katastrofalna" i da je jedini izlaz vakcinacija, navodeći da će se Krizni štab za borbu protiv korone sastati iduće sedmice.

„Da uvedemo sada restriktivne mere smirilo bi se i imali bi ponovo katastrofalnu situaciju. Jedini način je vakcinacija i podrška čitavog našeg društva procesu vakcinacije. Država je svoj posao uradila na najbolji način“, rekla je Brnabić.

„Medicinski fakultet nije uveo kovid sertifikate već samo pre ulaska u kliniku treba da se dostavi potvrda da student nije nosilac infekcije, tj. potvrda o vakcinaciji, o preležanoj bolesti, ili da je student negativan na virus. Dakle nema nikakvih kovid propusnica već samo provere“, rekla je za RTS Kisić Tepavčević, koja je i članica Kriznog štava za suzbijanje korona virusa.

28.9. (dan za koji se poklapa statistika hospitalizovanih i na respiratoru iz te objave): 8142 zvanično preminula od početka pandemije
18.8. (41 dan pre, broj dana unazad za koji on tvrdi da nije bilo nijednog vakcinisanog preminulog): 7183 zvanično preminula od početka pandemije
https://www.b92.net/info/koronavirus/statistika.php

959 zvanično preminulih tokom 41 dana, a navodno nijedan vakcinisan među njima u državi sa preko 40% vakcinisane celokupne populacije, toliko nijedna vakcina u istoriji čovečanstva nije štitila.

Dakle, definitivno fejk.

Kažu ljudi da je taj Blagojević posle toga kao u zemlju propao, ne odgovara na postove i poruke u kojima ga ljudi pitaju za izvor ovih podataka i više uopšte nije aktivan u toj grupi u kojoj je bio administrator.

Od 251 na respiratoru nema revakcinisanih, svi su nevakcinisani.

Do drastične ali i najbitnije razlike dolazi se u delu istraživanja koji su oboleli od kovida morali na lečenje u bolnicu. U slučaju nevakcinisanih to je 75.2 odsto, a vakcinisanih 24.8 odsto. Još uočljivija razlika je kada je reč o intezivoj nezi i stavljanju na respirator - odnos je dva vakcinisana pacijenta u odnosu na 33 nevakcinisanih.

SVE VEĆI BROJ LJUDI NA RESPIRATORIMA Ovo je broj novoobolelih od kovida tokom poslednja 24 sata, pozitivan SVAKI TREĆI TESTIRANI

Discussion

We have investigated a nosocomial COVID-19 outbreak involving the SARS-CoV-2 Delta variant among a highly vaccinated population. The attack rate among exposed individuals reached 23.3% in patients and 10.3% in staff, with 96.2% vaccination rate among exposed individuals. Moreover, several transmissions probably occurred between two individuals both wearing surgical masks, and in one instance using full PPE, including N-95 mask, face shield, gown and gloves.

In a recent publication by Bernal et al., the effectiveness of full vaccination with the Comirnaty vaccine against the Delta variant was high, although lower than against the Alpha variant (88% vs 93.7%) [9]. This was not the experience in Israel, with a rapid increase in cases since June 2021 despite a high vaccination rate [1].

Although reports of breakthrough infections are increasing [10-12], this communication emphasises several points. It challenges the assumption that high universal vaccination rates will lead to herd immunity and prevent COVID-19 outbreaks. This was probably true for the wild-type SARS-CoV-2 virus, but in the outbreak described here, 96.2% of the exposed population was vaccinated. Infection advanced rapidly (many cases became symptomatic within 2 days of exposure), and viral load was high. Another accepted view is that, when facing a possible mismatch between the SARS-CoV-2 variant and vaccine or waning immunity, the combination of vaccine and face mask should provide the necessary protection. Although some transmission between staff members could have occurred without masks, all transmissions between patients and staff occurred between masked and vaccinated individuals, as experienced in an outbreak from Finland [12]. We cannot rule out that protection measures were not optimally implemented, however, transmissibility in summer 2021 differs from our experiences in the previous 18 months. Whether this can be attributed to the low Cq and high transmissibility of the Delta variant is not clear. Of note, in our cases, in particular case patients, the time from vaccination was considerable. The shortest interval was 142 days (5 months), and many of our case patients advanced to severe disease. Data from Israel imply that the main reason for the increase in COVID-19 cases in summer is indeed waning immunity, and a third vaccine dose, 5 months after the second dose will possibly result in trend reversal [13,14].

Conclusion

This nosocomial outbreak exemplifies the high transmissibility of the SARS-CoV-2 Delta variant among twice vaccinated and masked individuals. This suggests some waning of immunity, albeit still providing protection for individuals without comorbidities. However, a third vaccine dose may be needed, particularly in individuals with risk factors for severe COVID-19. Appropriate use of masks, especially in high-risk settings is advised.
