The idea of immune passports is not good, scientists say
The idea of immune passports, which some countries intend to introduce, is not good, say scientists from the University of Amsterdam. They doubt that the immunity associated with the construction of antibodies to coronavirus infection is lifelong, writes the Czech information site Lidovky.cz.
Researchers even fear that the temporary protection against infection may last only six months. They are based on a study of the behavior of the coronavirus over the past 35 years.
The document was published after the British government signed a 10 million contract for the supply of antibody tests that the patient could develop after being infected with a coronavirus and thus be immunized against the virus.
The British television server Sky News reported about this only a few days ago. The United Kingdom promises future profits after building group immunity, and now that the situation is not favorable – at least a way to release the restrictions. The facts found during long-term monitoring of coronavirus show a weakness in their strategy, the publication writes.
According to Sky News, for 35 years, researchers in Amsterdam have regularly tested 10 men for four types of coronavirus. Most participants between the ages of 27 and 66 became infected again within 3 years. They concluded the study with the conclusion that immunity to coronaviruses is short-lived.
“After 12 months, we saw reinfection in patients, and there was also a significant reduction in antibody levels six months after the initial infection,” the researchers said. Between 1985 and 2020, participants were tested at intervals of six or three months. Although researchers acknowledge some of the limitations of the study, they also question the reliability of the so-called immune passports. If the protective immunity is to be lost within six months of infection, they are meaningless, the researchers said.
The World Health Organization (WHO) released a scientific summary on April 24, noting that some states are planning “immune passports” for people who have recovered from the coronavirus. Such a document would allow them to move more freely and theoretically ensure that they cannot spread the virus. At the same time, the WHO has warned governments not to use “immune passports” to facilitate easing restrictions on a pandemic outbreak.
