A new study from China reveals the unsettling news that antibodies against the novel coronavirus COVID-19 don’t last very long.
According to Business Insider, coronavirus antibodies dwindled to undetectable levels after just two or three months for 40% of asymptomatic people.
Of the study subjects who did show symptoms, the antibodies completely disappeared for 13% of them in the same time period.
Overall, asymptomatic people showed “a weaker immune response” in the months after they were exposed to the coronavirus.
For those trying to develop a vaccine, a poor immune response from people who have recovered from the virus is unwelcome news.
Dr. Anthony Fauci said earlier this month that immune responses to the coronavirus are inconsistent between different patients.
I have examples of people who were clearly infected, who are antibody-negative. Dr. Anthony Fauci National Institute of Allergy and Infectious Diseases
He added that those people likely have antibodies — just not enough for the test to detect. Other recovered patients, meanwhile, show high antibody counts.

Seven Leon County sheriff’s deputies have now tested positive for coronavirus. 

On Wednesday, LCSO reported that two deputies had tested positive. The department noted that others who came in contact with the two were self-isolating and would also be tested.

Monday evening, the department reported that five more deputies had tested positive for the virus.

The sheriff’s office says all seven deputies are “self-isolating at home.” Other deputies and staff who came into contact with them also are in isolation and will be getting tested, the office said in a news release. 

It was not clear how many deputies and staffers are in isolation.

Meanwhile, the Tallahassee Fire Department reported Monday that an administrator has tested positive. The department notified employees who work closely with the administrator and sent them to get tested. All employees who were tested came back with negative results.

Spokeswoman Sarah Cooksey did not identify the employee in an emailed statement to the Tallahassee Democrat.

TFD did not say when the administrator had tested positive, but according to a screenshot of an email sent to the Democrat, the administrator appears to have tested positive sometime last week.

The department says the positive-testing employee did not have any known work interactions with the general public.

“While most employees were not in close contact with the individual, we took steps to notify all the members of our department as to keep everyone well informed and up to date on the importance of our ongoing practice to take precautions related to reducing transmission of the COVID-19 virus,” Fire Chief Jerome Gaines said in a statement.

“The health and safety of our members and the public is our top priority.”
