My opinion is that there is very little attempt to show risk/reward of vaccine vs risk/reward of virus by age. Not to mention risk/reward of treatment, which I feel is non-existent in SA. I don’t think there is any serious attempt to calculate risk of adverse events versus risk of virus by age. I imagine as you get younger the risk of vaccine exceeds the risk of vaccine, most especially in children, not so?Younger population. Less testing can be an issue because people can die undiagnosed. Later COVID doesn't always show up on nasal swab.
Natural antibodies may or may not work. It's not that everyone who has had previous COVID doesn't get it again. You can see there are reinfections on the WC dashboard.
However, you can get natural immunity AFTER you vaccinate too. If the prevalence rate in the community is high, you will have constant exposure.
It is exceptionally irrational to want to avoid vaccine because of a very low risk of side effects when even a handful of covid hospitalisations and there are right now people from Langa, Kaya, Gugs etc in WC hospitals, so even one or two days of this will cancel out your fears of annual vaccine related deaths.
