Varför har ni inte vaccinerat er mot Covid-19 ?
Jag mindes fel, de hade kontakt med varandra. Dödligheten bland ovaccinerade hönor som "umgicks" med vaccinerade ökade och de vaccinerade hönorna spred extremt mycket mer virus än ovaccinerade.BirgitS skrev:

"Read’s group started their investigation by exposing vaccinated and unvaccinated Rhode Island Red chickens to one of five Marek’s disease strains that ranged from hot to cold. The hottest strains killed every unvaccinated bird within 10 days, and the team noticed that barely any virus was shed from the feathers of the chickens during that time. (The virus spreads via contaminated dust in chicken coops). In contrast, vaccination extended the lifespan of birds exposed to the hottest strains, with 80 percent living longer than two months. But the vaccinated chickens were transmitting the virus, shedding 10,000 times more virus than an unvaccinated bird.
“Previously, a hot strain was so nasty, it wiped itself out. Now, you keep its host alive with a vaccine, then it can transmit and spread in the world,” Read said. “So it’s got an evolutionary future, which it didn’t have before.”
But does this evolutionary future breed more dangerous viruses?
This study argues yes. In a second experiment, unvaccinated and vaccinated chickens were infected with one of the five Marek’s disease strains, and then put into a second arena with a second set of unimmunized birds, known as sentinels. In particular, the team was interested in a middle-of-the-road strain called “595” and whether it would become hotter.
It did. The virus spread to sentinel birds nine days faster if it came from a vaccinated chicken versus an unvaccinated one. In addition, sentinels died faster when exposed to vaccinated chickens versus unvaccinated chickens.
“One way to look at that experiment is that shows vaccinating birds kills unvaccinated birds. The vaccination of one group of birds leads to the transmission of a virus so hot that it kills the other birds, said Read said. “If you vaccinate the mothers, the same thing happens. The offspring are protected by the maternal antibodies of the mother and that allows the virus in the chicks to transmit before they kill the host. So they transmit and kill the other individuals.”
En egenskap hos vaccinet mot Marekvirus som spelade stor roll är att vaccinet hindrade viruset att ställa till med skada i värddjuret men det hindrade inte viruset att reproducera.
Gäller något liknande för covidvaccinen och SARS-CoV-2?

Man bör nog vara lite skeptisk till allt folk säger. Har nog aldrig hört just detta från honom vad jag minns. Men det finns många andra världen över som hävdar att man ska undvika dessa oljor. Synd att folk som försöker vara hälsosamma går på budskapen om dess nyttighet.P pmd skrev:

Som redan sagts så är det inte likt covidvaccin alls. Man har sett att när folk covidvaccineras så sjunker andelen som blir smittade och de som trots allt blir smittade smittar mindre än ovaccinerade. Så den där kycklingsviruset och -vaccinet är inte relevant i det här sammanhanget.S Surly skrev:Jag mindes fel, de hade kontakt med varandra.

Amerikanska smittskyddsmyndigheten CDC har från 4 april till 17 juli (deltavariantens uppgång) gjort en studie och kommit fram till att följande gäller efter att folk har smittats:

- De som inte är fullvaccinerade har mer än 10 gånger högre risk att läggas in på sjukhus än fullvaccinerade.
- De som inte är fullvaccinerade har 11 gånger högre risk att dö än fullvaccinerade.

En av de som skrev artikeln om vaccinet mot Mareks sjukdom hos höns har kommenterat diskussionen gällande studien och dess tillämplighet vid vaccination mot Covid-19. Jag rekommenderar läsningen. Det är alltid väldigt intressant och lärorikt att lyssna på när forskarna bakom en studie själva sätter sina resultat i olika perspektiv.S Surly skrev:Jag mindes fel, de hade kontakt med varandra.

Ny studie. Risken för att avlida i Covid-19 är 11 ggr större för den som är ovaccinerad.

Som jag skrev förut idag #4204 så pågick studien fram till 17 juli och enligt rapporten så dominerade delta från 20 juni. I tabellen är resultaten uppdelade på perioden för och efter den 20 juni så man behöver inte tänka sig utan det går bra att läsa.Ulltand skrev:

Du tänker fel. Den påbörjades i april och speglar alltså inte alls den smittan vi har nu med i stort sett bara Delta.
