Jeshan Posted September 19, 2021 Report Posted September 19, 2021 Like the Delta strain, unforeseen contingency when the original vaccines were invented. What if Covid repeatedly produces new virus strains? Will we need to repeatedly invent annual vaccinations to handle that issue? Hypothetical situation, but what if? Quote
BubberMiley Posted September 19, 2021 Report Posted September 19, 2021 Don't we already do that with the flu? Has that been a big deal? Quote "I think it's fun watching the waldick get all excited/knickers in a knot over something." -scribblet
Boges Posted September 20, 2021 Report Posted September 20, 2021 100% COVID is not the measles. It will mutate and immunity will wane. A vaccine is the safest way to build up an immunity against a virus that'll be with us for sometime. Quote
500channelsurfer Posted September 25, 2021 Report Posted September 25, 2021 Very generally, viruses morph and spread to be less dangerous and less deadly to their hosts. Biologically, species that kill off their prey too fast cause their own extinction. Over the very long-term, Covid strains will therefore become less virulent to the point where a vaccine may no longer even be needed; most active Covid strains will eventually become just like a common cold, if they do not fizzle out altogether like the 1918 flu strain. In the meantime, yes, I do agree a few more vaccines might be developed as some Covid strains might still be dangerous and potentially deadly. Quote
