How is it possible that an effective vaccine will be produced? Sorry if I'm totally misunderstanding the connection (no science background whatsoever...barely scraped my Science GCSE back in the day!), but all these reports coming out of South Korea that recovered covid 19 sufferers have caught the disease again has got me wondering how a vaccine would work if no meaningful or long lasting antibodies are produced? Hoping someone can explain!
From what i have read they believe immunity at best could be 2 to 3 years and they expect seasonal out break like the flu so could be a new programme of vaccines like they do with flu but it is all early days yet so its very hard to to know exactly what they are dealing with.
