Risk, uncertainty and fear of failure: Why scientists aren't celebrating a coronavirus vaccine yet
Scientific community wrestling with how to deal with both public hesitancy and overblown expectations for a potential jab
De säger i princip exakt det jag säger hela tiden. Och sluta med dina halmgubbar. Det finns ingen som säger att vaccinet är en bluff.
Risk, uncertainty and fear of failure: Why scientists aren't celebrating a coronavirus vaccine yet
Scientific community wrestling with how to deal with both public hesitancy and overblown expectations for a potential jab

One of the most basic issues is that, while early trials have delivered positive results, a vaccine is still very far from being guaranteed to work.
Speaking about the Oxford and Moderna trials in the UK and US, Professor Peter Jay Hotez, a professor at Baylor College of Medicine in Texas who is working on a separate, affordable vaccine for middle-income countries, said: "Yes, they had good responses in the 10 or so volunteers who received two doses of the vaccine. But to go from that to 'we're going to vaccinate the world', or vaccinate the UK or the US, is a big leap.
"There needs to be someone out there explaining this."
Once those vaccines are tested on tens of thousands of people in Phase III trials, there is plenty of potential for failure.
One of the greatest setbacks could be caused by "antibody-dependent enhancement" (ADE), also known as disease enhancement or immune enhancement, a rare phenomenon in which the presence of antibodies in an individual can trigger a worse infection. Efforts to develop vaccines for Sars and Mers, two other coronaviruses, found evidence of ADE in animals.
In other cases, it has been a major setback. Prof Bar-Zeev pointed to the case of a vaccine developed in the late 1960s for RSV, a common childhood illness, in which ADE was suspected as the cause of its failure.
"The vaccine was withdrawn from the market 51 years ago and we still don't have a good RSV vaccine … and the reason is because of enhanced disease," he said. It's an issue, he added, that the "entire Covid-19 vaccine community is keenly aware of… the safety of a Covid-19 vaccine is absolutely essential".
Even if Phase III trials are passed with flying colours, manufacturing to scale could take a long time and there is always the possibility of a RotaShield-type event, which would call for a serious ethical debate.
Just as concerning as safety issues is the still unanswered question of efficacy. It may be that, while candidate vaccines turn out to be quite safe, they aren't anywhere near effective enough to be worth using.
Vaccines can have the very useful effect of reducing the severity of infection, but the holy grail for a coronavirus vaccine would be to prevent transmission as well. Given the still uncertain nature of immunity to Covid-19 and how long-lasting it is, that could be an unachievable goal.
"If the immunity is short-lived then I think it's a little bit futile because to mount a massive campaign every few months to vaccinate God and the world against this virus is not going to be sustainable," explained Prof Kampmann. Such a vaccine would not be useless as it would protect the individual, but it's a long way from the notion some seem to have that "all we need is this one vaccine and the show is over".
