I was thinking that the current booster would just tide us over until the mRNA vaccines are updated for omicron. Hopefully then we can get a fourth injection and have longer lasting protection.

 

Or am I dreaming?

 

No one knows to be honest so you could not dismiss this idea out of hand.

This vaccine held up well against the Ancestral wild strain in terms of longevity....even with a drop off in neutralizing antibodies the 1st gen vaccine still had a greater affinity for the wild strain spike protein therefore the efficacy percentage remained reasonable.

So perhaps an omicron vaccine would behave the same.

What is more important, is that a bespoke vaccine gives better herd type immunity across populations so wide use, everywhere all at once, might give us a chance of killing this thing off....which needs to start with slowing the rate of mutation.

Especially if omicron immunity is effective against Delta...because even if Omicron burns out...there will be pockets of Delta...so ideally a new vaccine would still work well against Delta.

Perhaps the new vaccine would be more effective from whatever mutant omicron throws out next too.....It does look as though we have to try a new vaccine.
