Coronavirus: Antibodies cannot inhibit virus transmission, study finds


According to a study in England, people who were previously infected with coronovirus and who protected themselves by antibodies can still carry the virus and infect others.

The study, titled “SARS-COV-2 Immunity and Reinforcement Evaluation” (SIREN) and conducted between June 18 and November 24, 2020, also found that when re-creation is possible, it appears to be rare, After being ill for at least the first five months.

The study was published for the first time last weekend. It was written about the peer reviewed magazine BMJ And science journal NatureAmong other publications. Those participating in the study who were already ill (about 6,600), were confirmed by only 44 (less than 1%) viruses. In other words, the immune response from the first infection reduced the risk of the virus reverting to 83%.

Of the approximately 14,000 people who had not been infected in the first study, 318 tested positive for the virus (2.3%).

Researchers do not know how long conservation lasts beyond the study timeframe.

In addition, those who were inoculated usually did not suffer from serious illness. Only 30% reported any symptoms with possible recombination, compared to 78% of those who contracted the virus for the first time.

But, as noted, sometimes those who were recovered and then reinforced had a higher viral load, meaning that there was still a high probability that they would transmit the virus to others.

Last week, during a ceremony marking the vaccination of Israel’s two million citizens, Prime Minister Benjamin Netanyahu said he negotiated with the health minister and other professionals to make the green passport scheme a success at the earliest, “Joe Will allow us to start bringing life back to normalcy. “But he said,” When we do, we still have to wear masks for younger populations and those who are not vaccinated. “The study was not meant to provide information about the vaccine’s effects. In addition, researchers Stated that the goal was not to determine whether symptoms were better or worse during the second infection, and this question requires further evaluation. The subjects were mostly young, middle-aged women who compared older people anyway Has less severe symptoms.
Finally, the study was conducted before the British mutation, which may change the dynamics of its results. Some have suggested that the existence of the mutation will reduce the effectiveness of the immune response, but more research will be required. This is not the first study published on reinfection. A separate study that was published in November also found in England that people who had the virus are unlikely to contract again for at least six months after the first infection.
