Thanks mike for sharing . My buddhist friend was almost not able to walk after second jab . Now he refused to take further booster dose . But the interval between second jab and now is only 3 over months . Another friend father passed away after the first jab , he was an athelete .mikenz66 wrote: ↑Wed Nov 03, 2021 7:52 pm
I'm not expert, but vaccines are not drugs in the sense of penicillin, etc. They work by inducing the body to produce antibodies to target particular cell/viruses/proteins. When you have a new vaccine, whether it's for flu (flu vaccines get changed every year to keep up with variants) or covid, the body will produce more antibodies. Since different vaccines will induce the response in different ways, it may well be useful to use a different vaccine for a booster.
Also, as I understand it, the difficulty we have at present is that the vaccines are not effective at preventing someone being infected by the delta strain (it prevents infection with the original), because the delta variant uses a slightly different protein to bind to cells that it attacks. It's still effective at significantly reducing the severity of the infection, however, as it induces antibodies that can kill the infected cells (as I understand it - I'm not familiar with all the details, but had a chat with an expert a couple of days ago). Presumably boosters will soon have modifications (which understand have already been developed, but not rolled out yet) to make them effective against delta (and other new variants). This is the strategy with flu vaccines.
