In all honesty, it still will be a few more years before the entire planet can get to some sort of pre-Covid-19 socio-economic normalcy, with or without herd immunity. Until that time, preventive measures should be appropriately practiced, as there will be many new treatments and updated vaccine versions developed, as more empirical data from both the survivors and fatalities, of that virus, are documented.
Based on that premise and in the short-term, I will still probably be practicing prevention and rely on the rapidly increasing number of treatments that are being discovered, should I have the misfortune of contracting the virus. In the long-term, I will most likely get vaccinated with the latest version, of the Covid-19 vaccine, at year five or later. In my projection, the availability of reliable global data regarding the virus, the survivors, and fatalities will be available, at that time. Hence, not saying the current iteration of the Covid-19 vaccine is not safe, but the researchers then will probably/hopefully be able to develop a much more safer and reliable vaccine with less potential side effects.
