With some infections, like measles for example, once you get them, you rarely get them again. Whereas with others, like tetanus, one often does not develop immunity.
SARS-CoV-2 [the virus that causes Covid-19] is only one of five coronaviruses affecting humans — the other four cause common colds in adults and we don’t seem to develop good long-term immunity to any of them. Whether it will be the same for Covid‑19 remains unclear. Only time will tell. Unfortunately there is insufficient information to inform this critical question.Prof Lynn Morris of the NICD
Since Covid-19 is a new disease, there has not been an opportunity to study this. This is important to understand because Covid-19 is likely to become endemic and occur annually, like seasonal influenzaThe expectation from an infection disorder that you have survived would be that you would have mounted a response to it and fended it off. The human response would be the development of antibodies.
We already know about hundreds of reinfections in South Korea that occurred about 2 months ago, don't we?
Damn, so why are we waiting for a vaccine then? But my question is, if one gets this Covid19 and recoveres from it, can that person still get a vaccine?
