WHITHER HERD IMMUNITY?

It’s the tail end of the Ox year
Covid-19 is still rampant here
No sign of herd immunity
Due to virus’s mutating propensity

13 variants so far did it spawn
Ranging from Alpha to Omicron
In a short span of only two years
5.4m dead, more mortality fears

Despite travel restrictions and orders
Variants easily penetrate borders
Making them diffiicult to eliminate
In one swift blow….how unfortunate!

Vaccines provide some protection
But only for a certain duration
‘Cos antibody response wanes
Depends on type and virus strains

Shown to evade previous immunity
Even full vaccination is no guarantee
So boosters are periodically needed
Woe betide one if advice isn’t heeded
