There is so much information coming out almost daily regarding immunity to covid19. Immunity is a big public concern since there have been conflicting reports of whether the antibodies protect us from future infections. If we are unable to become immune, the fear is that we will be reinfected multiple times.
According to a recent article in the NY Times, even if the antibodies in someone who had an asymptomatic infection go away, your immunity is there to stay, at least for a while as shown in a new study.
It is normal to build up immunities to many different bacteria and viruses we come in contact with daily. Our bodies fight most of these off and we develop immunity. Our cell phones and many other common things that we touch are filled with bacterium and viruses that we adapt to.
The science is now suggesting that you maintain immunity for at least a year even if the antibodies have gone away. This is based on a study published in Nature Medicine. Antibodies — protective proteins made in response to an infection — may last only two to three months, especially in people who never showed symptoms while they were infected. This does not mean you will get reinfected, since even low levels of powerful neutralizing antibodies may still be protective, as are the immune system’s T cells and B cells.
Scientists do know that immunity to SARS and MERS can last a year or more, although the idea of immunity certificates as certain people such as Governor Cuomo has suggested is a good idea.
It is also important to realize that immunity may involve more than T cells and B cells and may develop genetically as well within the cells of your body, although this article does not cover that aspect of how we develop immunity to SARS2 otherwise known as covid19.

You May Have Antibodies After Coronavirus Infection. But Not for Long.
Antibodies to the virus faded quickly in asymptomatic people, scientists reported. That does not mean immunity disappears.

It’s a question that has haunted scientists since the pandemic began: Does everyone infected with the virus produce antibodies — and if so, how long do they last?
Not very long, suggests a new study published Thursday in Nature Medicine. Antibodies — protective proteins made in response to an infection — may last only two to three months, especially in people who never showed symptoms while they were infected.
The conclusion does not necessarily mean that these people can be infected a second time, several experts cautioned. Even low levels of powerful neutralizing antibodies may still be protective, as are the immune system’s T cells and B cells.
But the results offer a strong note of caution against the idea of “immunity certificates” for people who have recovered from the illness, the authors suggested.
