omiljeni Posted April 8, 2021 Posted April 8, 2021 1 hour ago, Halvard said: U Poljskoj 954 umrlih juče poremetilo im se brojanje, verovatno zbog Uskrsa. u ponedeljak i utorak su imali samo po 60, pa je zbog toga danas veći broj.
Jozef K. Posted April 8, 2021 Posted April 8, 2021 Pa da li je taj brazilski soj postao negde dominantan osim u Brazilu?
Halvard Posted April 8, 2021 Posted April 8, 2021 14 minutes ago, Jozef K. said: Pa da li je taj brazilski soj postao negde dominantan osim u Brazilu? Ubrzano se širi po Južnoj Americi. U Urugvaju u poslednjih nedelju dana ima preko 250 smrtnih slučajeva, što je oko 20% umrlih tokom čitave epidemije. U Čileu uprkos jako uspešnoj vakcinaciji ponovo idu u lockdown jer su im brojke novozaraženih u poslednjih nedelju dana sustigle one sa vrhunca najgoreg talasa iz juna prošle godine. Peru je pre nedelju dana oborio rekord po broju novozaraženih, a juče po broju umrlih. 1
omiljeni Posted April 8, 2021 Posted April 8, 2021 pre par dana sam na espn sajtu video vest da je u Kanadi ceo hokejaški tim imao pozitivan test i da je kod svih ta brazilska P1 vrsta korone Vankuver tim u NHL
omiljeni Posted April 8, 2021 Posted April 8, 2021 piše 21 igrač i 4 trenera. valjda im samo 4 igrača nisu inficirana. Quote The P.1 variant has seen a spike in the Vancouver region over recent weeks. On Tuesday, the province announced 1,068 new cases of Covid-19, including three deaths and 207 new cases from variants of concern.
Dankan Ajdaho Posted April 9, 2021 Posted April 9, 2021 (edited) Šta kažu najnovija istraživanja u vezi P1 i postojećih vakcina? Tj, koja se najbolje nosi sa njim? Edited April 9, 2021 by Dankan Ajdaho
Amos Posted April 9, 2021 Posted April 9, 2021 Sad jedno potpuno naivno pitanje. Ukoliko brazilski soj ima veću smrtnost, da li to znači i da će brže da nestane? Po onoj teoriji da virusi sa većom smrtnošću prebrzo ubiju svoje hostove da bi se suviše širili. Ili to kod Covida nema veze zbog mnogo duže inkubacije nego kod virusa sa velikom smrtnošću poput Ebole?
vememah Posted April 9, 2021 Posted April 9, 2021 Da, po onome što se pisalo ogromna većina pacijenata nije zarazna kad dođu u teško stanje, tako da to hoće li se oporaviti ili umreti gotovo uopšte ne utiče na širenje zaraze. 1

Fajzer i AstraZeneka po jednom još nerecenziranom istraživanju na bazi seruma navodno lepo rade, otprilike kao za britansku varijantu. Veliko pitanje je za Sinovak koji se koristi u Brazilu. Quote We next performed neutralization assays using serum collected from individuals who had received either the BNT162b2 Pfizer-BioNTech or ChAdOx1 nCoV-19 Oxford-AstraZeneca vaccine Figure 7 (Supasa et al., 2021;Zhou et al., 2021). For the Pfizer BioNTech vaccine serum was collected 4-14 days following the second dose of vaccine administered three weeks after the first dose (n=25). For the Oxford-AstraZeneca vaccine serum was taken 14 or 28 days following the second dose which was administered 8-14 weeks following the first dose (N=25). Geometric mean neutralization titres against P.1 were reduced 2.6-fold (p<0.0001) relative to the Victoria virus for the Pfizer-BioNTech vaccine serum Figure 7A,C and 2.9-fold (P<0.0001) for the Oxford-AstraZeneca vaccine Figure 7B,D Table S4. Neutralization titres against P.1 were similar to those against B.1.1.7 and only a minority of samples failed to reach 100% neutralization at 1:20 dilution of serum, considerably better than neutralization of B.1.351, where titres were reduced 7.6-fold and 9-fold for the BNT162b2 Pfizer and ChAdOx1 nCoV-19 AstraZeneca vaccines respectively. Figure 7 Neutralization of P.1 by vaccine serum. (A) Pfizer vaccine, serum (n=25) was taken 7-17 days following the second dose of the Pfizer-BioNTech vaccine. FRNT titration curves are shown with Victoria, B.1.1.7 and B.1.351 as comparison (Supasa et al., 2021;Zhou et al., 2021). (B) AstraZenca vaccine, serum was taken 14 or 28 days following the second dose of the Oxford-AstraZeneca vaccine (n=25). (C-D) Comparison of FRNT50 titres for individual samples for the Pfizer and AstraZeneca vaccine between Victoria, B.1.1.7, B.1.351 and P.1, the Wilcoxon matched-pairs signed rank test was used for the analysis and two-tailed P values were calculated, geometric mean values are indicated above each column. https://www.biorxiv.org/content/10.1101/2021.03.12.435194v2.full.pdf Edited April 9, 2021 by vememah 2
