Why you can't compare Covid-19 vaccines.

In the US, the first two available Covid-19 vaccines were the ones from Pfizer/BioNTech and Moderna. Both vaccines have very high "efficacy rates," of around 95%. But the third vaccine introduced in the US, from Johnson & Johnson, has a considerably lower efficacy rate: just 66%. The fourth one, from Astra-Zeneca, has an efficacy of about 67%.

Look at those numbers next to each other, and it's natural to conclude that one of them is considerably worse. Why settle for 66% when you can have 95%? But that isn't the right way to understand a vaccine's efficacy rate, or even to understand what a vaccine does. And public health experts say that if you really want to know which vaccine is the best one, efficacy isn't actually the most important number at all.

Would you advice a 78yr old woman with no known medical issues (except alzheimer's at early stages) to undertake the (any of these) vaccine?

It's better for her to get the vaccine, even if she gets a few side effects for a day or two, it's 'better' than the actual virus

The lady is family, so we decided to use her as a guinea pig.
From what I saw, sioni kama nitaendea hio vaccine willingly.
She almost died. And she's only 46. Now think of a 78-yr old.

Not covid symptoms, those are what are called Adverse Effects Following Immunization, AEFIs. Let him get in touch with the pharmacy department of the facility where he had it so that the same can be documented here https://pv.pharmacyboardkenya.org.

Personally when i had the vaccine slightly over a fortnight ago I ended up with joint pains/ weakness, fever, excessive sleeping that lasted about 3 days. Some of my colleagues had headaches, some even diarrhea, and yet others had none. The point is these AEFIs are largely idiosyncratic and we insist they must be reported and documented.

Specifically with the AZ vaccine, the young seem to suffer those AEFIs more than the elderly. I hag some of my relatives and friends' parents vaccinated in the last several days. I've been following them up and, to the last man and woman, none has experienced any AEFI.
