of mRNA doses given out and the tracking Health Organizations have done, we already know the side effects. It's a pity that Mark persists, but he's a fellow forum member an we try to help.
btw, mRNA vaccines have been in development for decades...and that includes voluminous testing...the technology is well understood...thank heaven we've been able to use it successfully because we're likely to need it again before too long.
Anyone who questions or complains about mRNA vaccines at this point is just trying to muddy the waters...only they can answer why they're doing it, because the biological science doesn't support them.
