Good news: COVID survivors may have four months of protection – Harvard Gazette

People who survive serious COVID-19 infections have long-lasting immune responses against the virus, according to a new study led by researchers at Harvard-affiliated Massachusetts General Hospital (MGH).

The study, published in Science Immunology, offers hope that people infected with the virus will develop lasting protection against reinfection. The study also demonstrates that measuring antibodies can be an accurate tool for tracking the spread of the virus in the community.

Four months. Because they have not yet been able to follow it for longer since it is a new virus. Another study finds “strong antibodies” after 5-7 months.

From comments made by experts, there is evidence of other forms of immunity present besides the antibodies measured in this study, and those other forms of immunity may last for years or decades. This is all very good news!

My doctor says I had symptoms of Covid-19 back in March and suggested in May that I get an antibody test. I declined because at that time, the accuracy of the test was unknown and the result was not actionable. With this new information, such a test would give an indication that I had some immunity, which would now be valuable to know.

On March 1st, I had the first inkling of a head cold. By the evening of March 3rd, I definitely had a head cold. This evolved quickly to low grade fever and body aches and, within a few days, and (unusual for me) a dry hacking cough that lasted until March 23d, went away’ish for about 3 days, then came back for a few days, and finally went away. Immediately prior to this I had been in close contact with Chinese citizens newly arrived (for education) from China; several of them were wearing face masks suggesting they were symptomatic of something. You may remember that China had a large outbreak of Covid-19 at the time. While air travel from China was allegedly shut down, in fact, hundreds of flights continued during the weeks after the “shut down”.

Update: The media loves big scary “re-infection” stories. Took 30 seconds to find studies reporting on “re-infection” of influenza and other viruses. While not common, this happens among other viruses. From the mediots reporting, you’d think that (a) CV-19 is the first time we’ve seen re-infection from a virus, (b) you have no immunity after you’ve had CV-19, and (c) CV-19 is the only virus to have asymptomatic cases (in reality, up to 75% of influenza cases have been reported as asymptomatic).

Mix the public health preference for fear mongering, inconsistent, contradictory and incoherent messaging with click-bait media morons and you get lots of false news reports.
