In the new study, Dupont and fellow researchers examined convalescent sera from 38 individuals, representing a mixed cohort of patients and healthcare workers, all of whom were infected in wave 1.

A previous study by some of the same team showed SARS-CoV-2 antibody levels beginning to drop after reaching peak levels at about three to five weeks POS, and it wasn't known if the drop kept happening beyond the three-month point POS. Hopes that wave of infections had peaked fade July 22, The overall number of estimated cases is 60,, which indicates that new cases are still on the rise in the UK.

Furthermore, the researchers found evidence that a past infection with one of four human coronaviruses that cause the common cold may provide some protection against infection with SARS-CoV-2, the virus that causes COVID Stay informed with live updates on the current COVID outbreak and visit our coronavirus hub for more advice on prevention and treatment.

Governments around the world are doing this through mass vaccination. These antibodies can then inactivate SARS-CoV-2 if exposed to the virus, either reducing the severity of an infection or stopping it entirely. While vaccines are crucial in turning the tide of the pandemic, people also develop antibodies following a SARS-CoV-2 infection. Given that this is the case for millions of people around the world, scientists are interested in better understanding how long the SARS-CoV-2 antibodies may be effective.

Determining this could inform vaccine development and help governments better manage the spread of SARS-CoV-2 in the future. Scientists are also interested in whether antibodies developed in response to one of the common cold coronaviruses may offer protection against SARS-CoV Speaking to Medical News Today , Dr.
