Immunity After a COVID-19 Infection May Not Be Lasting

If the virus that causes Covid-19 always circulates, will it always have the capacity to make us so sick? Experts see four scenarios. https://t.co/ErULTDwu89

Health Editor’s Note: Two more cases of re-infection with COVID-19 have come to light in Belgium and the Netherlands. Earlier this week, we had a man in Hong Kong who demonstrated a re-infection with COVID-19. He fully tested negative and then became positive again with a slightly different COVID-19 strain, four and one half months after being declared COVID-19 free.
Re-infection cases are probably going to be quite rare, but deserve to be look at when preparing a vaccine. The second time these people had tested positive, the second infection is a slightly different strain of COVID-19, not identical to the first one they contracted.
These three people had a first and then a second infection after clearing the first infective virus from their bodies. All three have a different type of COVID-19 virus than their first infection.
The clear fact that these people could be re-infected is concerning for two reasons. If you can become reinfected, that means the first infection did not leave you with an immunity and the second is that the COVID-19 vaccine may not be to be made as effective as it needs to be. I would propose a third scenario, where COVID-19 mutates slightly, as viruses easily do into another form of the COVID-19 virus, which the person previously infected has not already had, thus no immunity to this new form. Currently the typical yearly flu does this every flu season/every year and it is guesswork to put together a flu vaccine that will be effective for the next year’s type of flu. COVID-19 is just completing this process at very high speeds…Carol
