Lite mer pre-vaccine nostalgi.
Från maj 2020, när experter fortfarande kunde saker. Vi visste redan då att vaccinet inte kommer skydda mot smitta. Vi visste redan då att naturlig immunitet skyddar inte mot smitta.
Välkommen till idiocracy.
Michael Mina, an infectious diseases epidemiologist at Harvard’s T.H. Chan School of Public Health, thinks achieving sterilizing immunity with a vaccine will not be possible for Covid-19. Experience with human coronaviruses — and with multiple pathogens that cause colds — shows immunity that develops after infection with respiratory tract infections is not lifelong. In some cases, the duration is measured in months, not years.
“If [infection with] natural coronaviruses doesn’t do it, I don’t think that we should necessarily expect or have the anticipation that we’ll be able to get there with the vaccine,” said Mina, who is also associate medical director of clinical microbiology at Boston’s Brigham and Women’s Hospital.
Munster agreed trying to develop vaccines that confer sterilizing immunity would be a heavy lift with this coronavirus. “I think we really need to focus on what are the fastest achievable true public health goals of the vaccine, which is protecting the vulnerable people against pneumonia and protecting health care workers as well,” he said.
Earlier this week Moderna, the Cambridge, Mass.-based biotech, said eight people in a Phase 1 trial of its Covid-19 vaccine developed neutralizing antibodies to the virus.
Neutralizing antibodies should protect against severe Covid-19 disease, Kanta Subbarao, a vaccine expert who is director of the World Health Organization’s influenza collaborating center in Melbourne, Australia, recently wrote in a commentary in the journal Cell Host and Microbe.
But Subbarao told STAT she wouldn’t be surprised if neutralizing antibodies don’t protect against infection in the upper airways. Like Munster, she doesn’t think that’s reason not to pursue these vaccines.
“Converting this infection to a upper respiratory illness would be, I think, quite a lot better than where we are today,” said Subbarao, who worked on vaccines for SARS, a closely related coronavirus that caused an international outbreak in 2003.
Subbarao said setting public expectations of what these vaccines will be able to achieve is critical.

Jag kommer ihåg hur Michael Mina i början av pandemin föreslog ett covid-snabbtest som med hyffsat hög träffsäkerhet kunde visa huruvida man var smittsam eller inte.
Observera, inte huruvida man var infekterad eller inte, utan huruvida man var infekterad OCH smittsam.
Man skulle göra ett billigt test varje morgon hemmavid, och var det positivt så skulle man inte gå ut den dagen.
Men den abstraktionen är ju naturligtvis för svår för dom flesta IQ <90 personerna som skriver i den här tråden.
"ööh vaddå 80% skydd. Antingen skyddar det eller så skyddar det inte. Jag har en granne som fick covid trots han var dubbelvacinerad. Det bevisar att vaccinet har 0% effektivitet".
Det kanske skulle funka i några länder i Asien, där folk har högre IQ, men i Sverige är IQnivån för låg. Vi kan ju inte ens förstå hur munskydd kan vara effektiva i den här pandemin.
