This is a very important point. We don't know enough about long term effects yet.
In the same vein, we do not even know if herd immunity really is a thing here, and what thing it would be. E.g. the guy from Hong Kong who got reinfected (first time severe symptoms, second time no symptoms) was probably infectious the second time again. Herd immunity only works if the people who are immune are not infections and therefore cannot (re-(infect each other and more importantly the vulnerable population.

- ceejayoz 6y agohttps://en.wikipedia.org/wiki/Herd_immunity https://en.wikipedia.org/wiki/Herd_immunity > Herd immunity was first recognized as a naturally occurring phenomenon in the 1930s when A. W. Hedrich published research on the epidemiology of measles in Baltimore, and took notice that after many children had become immune to measles, the number of new infections temporarily decreased, including among susceptible children. (To be clear, though, I don't think the herd immunity strategy is a good one for COVID-19.)
- chillwaves 6y agoThe concept makes no sense. As soon as a carrier hits a group that does not have widespread immunities, you will get a disease cluster. Not only do you have to have a huge portion of the population exposed to the disease, you need to maintain that proportion indefinitely AND will still deal with occasional flair ups among vulnerable communities. That's not what most people think when they hear the word "immunity".

- latchkey 6y agoI guess I should have said 'Successful herd immunity'. The sentence after what you quoted is: "Mass vaccination to induce herd immunity has since become common and proved successful in preventing the spread of many infectious diseases."
