Shield

i finally got my Covishield, it's got a tony Oxford tag. 

Hope it helps my English, and my accent just a tad! 

It's made by an equine farmer, who mates mare and stud! 

Dare i pray for magic side-effects, a makeover from dud? 

With the hype and paraphernalia, the spacey moniker AstraZeneca, 

I want more than not to cough, even a fatal pyrexia's panacea. 

'Shield, it's time to give me energy, redoubled cheer, and joy in plenty, 

And please a mental deletion of the pernicious pandemic of 2020!
