I agree with him and you, but all vaccines have been brought out with limited testing and I beleive science has improved over the years so given the timescale we have to take a chance. Its very age related a 70yr old can't wait 20yrs for a long term test where a 20 yr old canThink I understand where he's coming from,
The virus/antibodies continues to exist in the body for a time but nobody knows how long, could be 6months, 6 years etc. We are all crash-test dummies because, arguably, we had no other option. No doubt we will also find out in time that it varies depending upon your historical DNA - Denovian etc or what Zombie plaster mix you prefer. Time will tell, a lifetime test.
Conceivably, the anti-bodies might turn around and attack our own bodies - that has already happened to some who caught the real thing - who knows? Lots of youngsters have been test hamsters for E's at raves without knowing the long term effects, You takes yer shot, or not, and takes yer chances.
